Abstract With the continuous growth of the global population and the increasing demand for sustainable food security, bread wheat (Triticum aestivum L.) plays a vital role as one of the major sources of calories and protein for a large portion of the world’s population. However, its production in temperate and arid regions such as Iran is severely constrained by abiotic stresses, particularly terminal drought and heat stress. Earliness is an important agronomic trait in wheat that enables plants to escape such end-season stresses. The present study aimed to evaluate the genetic diversity among 48 bread wheat genotypes (40 lines and 8 checks), identify early-maturing and high-yielding lines, and assess the genetic structure of phenological and yield-related traits under the environmental conditions of Kermanshah, Iran. The experiment was carried out during the 2023–2024 cropping season at the Research Farm of the Faculty of Agriculture and Natural Resources, Razi University of Kermanshah, using a randomized complete block design (RCBD) with three replications. The seeds were selected from advanced lines derived from crosses among nationally released cultivars. Phenological, agronomic, and biochemical traits were recorded. Analysis of variance (ANOVA) revealed highly significant differences among the genotypes for all studied traits, indicating considerable genetic potential for use in wheat breeding programs. Genotypes 10, 5, and 22 were identified as the earliest lines, while genotypes 1 and 24 were the latest. The highest grain yields were recorded for genotypes 32 (770.37 g/m²), winter backcross ‘Roshan’ (766.40 g/m²), 30 (760.15 g/m²), and 10 (696.79 g/m²). Grain yield showed significant positive correlations with spike weight per square meter, harvest index, and spike number per square meter, emphasizing the importance of these traits in yield improvement. Principal component analysis (PCA) extracted six principal components explaining 81.29% of the total variance, with the first component mainly associated with phenological traits and the second with yield-related traits. Cluster analysis grouped the genotypes into five clusters, among which cluster III comprised the earliest-flowering and earliest-maturing genotypes, characterized by the highest mean spike number, grain yield, and biological yield. These findings confirm the presence of sufficient genetic diversity for the improvement of phenological and yield-related traits in bread wheat. Identifying early-maturing, high-yielding lines (particularly those in cluster III) represents an effective strategy for developing stress-tolerant cultivars and improving water-use efficiency in future wheat breeding programs.

The Poaceae family plays an important role in human and animal nutrition. Oat, as a cereal and high-quality forage, has special significance. Increasing forage production is required due to livestock demand and resource limitations. This study evaluated the morphological, phenological, forage, and chemical diversity of 40 hexaploid oat genotypes with the aim of identifying genotypes possessing desirable forage and agronomic traits. The experiment was conducted during the 2022–2023 cropping season at the Research Farm of the College of Agriculture and Natural Resources, Razi University, Kermanshah Province. A randomized complete block design (RCBD) with 40 treatments, consisting of forage-type genotypes selected from previous trials, was applied with three replications. Analysis of variance revealed significant differences for all traits except plant height. The results of this study showed that there were significant differences between the studied genotypes in terms of most agronomic and qualitative traits. The RYHTI, CHINESE, HOUDAN and STORMONT IRIS genotypes were superior in quantitative traits such as fresh forage weight, harvest index and grain yield, number of spikes and straw yield, while the JARLE, VENTURA, RUBIDA and ALASKA genotypes were distinguished by qualitative traits such as ash content, crude fat percentage, crude protein percentage and crude fiber percentage. Phenologically, the KENT genotype was introduced as the earliest and the SUPPORT genotype as the latest, which are suitable for regions with short and long growing seasons, respectively. The results of cluster analysis also confirmed the findings of the mean comparison and introduced the JARLE and FORWARD genotypes as well as ACACIA and CHINESE genotypes as superior in terms of a set of agronomic and qualitative traits. The correlation study of traits showed that some quantitative traits had a negative correlation with qualitative traits, while there was a positive correlation between some qualitative traits, indicating that genotypes focused on a group of traits. Finally, using the ideal genotype selection index, the ACACIA genotype was introduced as the superior genotype for continuing breeding programs.

   The Zagros forests are the second largest forested region in Iran, predominantly composed of oak trees, which is why these forests are referred to as the Western Oak Forests. A portion of the Zagros forests is located in Kermanshah Province, where two oak species, Quercus brantii (Persian oak) and Quercus infectoria, are distributed. The objective of this research was to investigate the quantitative and qualitative characteristics of oak seeds in Kermanshah Province. For this purpose, seed samples were collected from various locations within the province's forests and tra  orted to the laboratory. In the laboratory, quantitative traits of the seeds such as the weight and length of the whole fruit, length, weight, diameter, and volume of the nut (achene), as well as the weight and thickness of the cupule were measured for both species. Subsequently, after determining the moisture content and pest infestation rate of the seeds, the concentrations of iron, copper, zinc, manganese, phosphorus, and nitrogen, along with the protein content of the seed coat (pericarp) and kernel, were analyzed. Finally, statistical software was used to analyze the quantitative and qualitative data of the seeds. The results revealed that all quantitative and qualitative characteristics of the seeds from both species, collected from different locations across the province, exhibited statistically significant differences both intra species and inter species.    Keywords: Chemical elements, Oak seed, Quercus infectoria, Quercus brantii

  Oat is one of the most important cereals in the world, essential for both humans and animals due to its significance as a key food source. With increasing public awareness of healthy dietary habits, oats have attracted more attention from scientific researchers and industries. Since limited efforts have been made by researchers to identify high-yielding varieties, there is an urgent need for breeding and identifying improved oat cultivars with high nutritional value. To achieve suitable genotypes or varieties for autumn and spring cultivation, an experiment was conducted during the 2022–2023 growing season at the research farm of the College of Agriculture and Natural Resources, Razi University, located in Kermanshah Province. The experimental design was a randomized complete block design with 44 treatments, including selected grain genotypes from previous experiments, conducted in three replications. After seed preparation, oat planting was carried out manually in both autumn and spring at a density of 400 plants per square meter. The results showed that the genotypes 291sv955057-35 and Brusher had the highest grain yield in autumn, producing 1505 and 1510 grams of grain per square meter, respectively. In the spring season, the genotypes Wandering (1183 g/m²), Carrolup (1152 g/m²), Quoll (1152 g/m²), Bannister (1149 g/m²), and Wintaroo (1131 g/m²) had the highest grain yields among the tested genotypes. The lowest grain yield in both autumn and spring was observed in the Titus genotype. A significant difference was observed between oat genotypes in terms of thousand-kernel weight across different cultivation seasons. The Wallaroo and Paramo genotypes had the highest thousand-kernel weights in autumn and spring, respectively, while the Dolphin97 genotype recorded the lowest thousand-kernel weight in both seasons. The longest spike length in both autumn and spring was observed in the Dalyup genotype. Regarding plant height, Dolphin97 and Mitika recorded the tallest and shortest plant heights, respectively, in both seasons. Biological yield results were entirely different, as the Oh1022 genotype had the highest biological yield in both autumn and spring cultivation. Conversely, the La Pervision and WA-oat genotypes recorded the lowest biological yields in autumn and spring, respectively. This indicates the strong adaptability of the Oh1022 genotype to different environmental conditions. Therefore, this study suggests the possibility of achieving high-yielding oat genotypes under spring cultivation conditions. If these results are repeated, the identified genotype(s) could be recommended to farmers.

   In order to study agronomic evaluation of recombinant inbred lines resulting from the wheat cultivars crossing, 450 recombinant inbred lines (RILs, F6) derived (three populations) from the crossing of Gascogen × winter backcross of Roshan, Marvdasht × MV17, Marvdasht × Shahpasand were evaluated. The experiment was carried out as an augment design in Research Farm of the Campus of Agriculture and Natural Resources, Razi University, Kermanshah, in 2020. The control treatments included five bread wheat cultivars (Roshan, Shahpasand, Morvdasht, Kraichov, MV17, Gascogen), the augment design was in the form of randomized complete block design (RCBD) with eight replicates, and the lines were randomly placed inside them.The results obtained from the correlation analysis showed that kernel yield per square meter had a highly significant positive correlation with straw yield, plant height, peduncle length, flag leaf length, spike length, spike weight, number of kernel per spike, weight of kernels per spike, thousand seed weight, number of spike per m2, weight of spike per m2, weight of stem and leaf per m2, biological yield and harvest index. The results of path analysis showed that number of spike per m2 had the highest correlation and also highest direct effect on kernel yield. According to the results obtained from factor analysis, five main components justified 76.70 percent of the total variation among data. Cluster analysis divided the genotypes into five groups. Generally, the results showed that the lines of the first group were superior to the other groups in terms of the most of the evaluated traits. Therefore, the lines in the first group could be sugessted for further breeding expriments. Key words: Augment, bread wheat, cluster analysis, recombinant inbred lines.

      Abstract: Considering the increasing rate of the world's population and the increasing demand for agricultural products, the cultivation of greenhouses in order to increase the production per unit area is very important. Environmental stresses such as high temperature, severe cold, drought, salinity and heavy elements have a negative effect on plant metabolism. Salinity is one of the most common environmental stresses that affects the growth and development of plants. Seeds are highly vulnerable to stress during the planting stage until the seedling is established. Biofertilizers have microorganisms that can help improve plant nutrition by methods such as fixing nitrogen, dissolving phosphate, releasing potassium ions, or providing iron and other required elements. In order to investigate the characteristics of greenhouse cucumber seeds (Nagin) under salinity stress conditions, a factorial experiment was conducted in the form of a completely randomized design with three repetitions, three levels of potassium (control, 100 and 200 mg/liter with potassium sulfate), two levels of fertilizer. Biology (control and bacillus sativa bacteria (CFU/ml) and three levels of salinity stress (control, 7 and 14 dS/m with sodium chloride) were carried out. The seeds were cultivated in Petri dishes and the treatments were applied and the germination percentage, germination speed, Average germination and seed strength index were calculated. Increasing the concentration of potassium in high salinity created positive effects in all the investigated traits. The interaction of treatments applied on greenhouse cucumber seeds increased seed vigor index, radicle length, seedling wet weight, shoot and seedling dry weight. However, biofertilizer in the laboratory did not have a significant effect on the examined traits.

   This research was conducted to investigate the effects of probiotics B. subtilis, B. coagulans, S. cerevisiae, and whey powder on some quantitative and qualitative characteristics of egg, blood parameters, and histomorphological characteristics of ileum in Lohmann LSL-lite laying hens in two experiments. In both experiments, there were six repetitions and there were 6 birds in each repetition, for 12 weeks. The first experiment was conducted with 288 Lohmann laying hens. The experimental diets consisted of a basal corn-soybean meal, the factors examined in this research were: B. subtilis 109 CFU at the rate of one gram/kg, whey powder at the rate of one gram/kg, and S. cerevisiae at the rate of 3 grams/kg. The control group received a standard diet without any additives. The other groups received a standard diet with B. subtilis, WP, S. cerevisiae, or a combination of them. No synergistic effect was found between WP, B. subtilis, and S. cerevisiae in studied parameters other than malondialdehyde level. The triple interaction effects of whey powder, S. cerevisiae, and B. subtilis in the diet reduced the amount of malondialdehyde compared to the group that received whey powder or B. subtilis alone or a mixture of them (P < 0.05). In the birds receiving whey powder, the length of villus (ileum) increased significantly compared to the control group, as well as the egg weight and specific gravity increased significantly compared to the control group.In the birds receiving Bacillus subtilis, the length and width of the villus (ileum) increased significantly compared to the control group, and the calcium, total protein and TAC levels in the serum increased significantly compared to the control group. Egg weight (at week 81-86) was improved in the group that received S. cerevisiae compared to the control. The birds that received whey powder and B. subtilis simultaneously tended to increase the length of the villi compared to the control group. A synergistic effect on egg weight and mass, and an improvement in their serum calcium levels was observed. In the second experiment, 144 Lohmann laying hens were used. The birds were fed a basal diet (control, CON), the basal diet supplemented with 1 g/kg WP, 1 g/kg B. coagulans (4*106 CFU) probiotic, and 1 g/kg WP plus 1 g/kg B. coagulans probiotic. Hens fed B. coagulans exhibited greater villi width and yolk color than Hens not fed it, however, their shell thickness and percentage of shell decreased. Birds receiving whey powder and B. coagulans had a significant synergistic effect on performance (egg production and mass). They also showed a tendency to decrease FCR. In light of these results, the simultaneous use of the these factors investigated in this experiment has no harmful effects on production performance, egg quality, and blood parameters in Lohmann's laying hens.

Abstract The present study was conducted with the aim of investigating the reaction of different wheat cultivars to the Un1 and Gi1 strains of Xanthomonas translucens, the bacterial leaf sterak (BLS) of wheat in Kermanshah province. At first, proving the pathogenicity of the strains was done by the pathogenicity test. In the next step, 17 wheat cultivars were planted in plastic pots containing a mixture of sand and gravel in a factorial method in a completely random design in three replications. Then, at the stage of two or three leaves, they were inoculated with a suspension of Xanthomonas translucens bacteria, with a concentration of 107-106 (CFU/g) by injection under the epidermis. The percentage of leaf surface contamination was noted and evaluated two weeks after contamination. Also, in all the experimental treatments, the weight of one hundred seeds was measured as one of the performance indicators. Data analysis was done by SAS software and comparison of means was done using Duncan's test. According to the results, the reaction of the studied cultivars to Xanthomonas translucens strains was different. So that the reactions were different and varied from sensitive to tolerant. The number of cultivars with high sensitivity such as Pishgam and Marvdasht were less than those with semi-sensitive and moderate sensitivity. In addition, the number of seeds per spike and hundred-seed weight of cultivars infected with Un1 and Gi1 strains were significantly lower than control cultivars (inoculated with distilled water). Overall, none of the studied cultivars had complete resistance to UN1 and GI1 BLS strains.

   Abstract This research was conducted to investigate genetic diversity and identify markers associated with agronomic traits in oat genotypes. For this purpose, 361 oat genotypes (Avena sativa L.) received from the Australian Grain Gene bank (AGG) were evaluated within a square lattice design in two replications in the cropping year (2017-2018) under irrigation conditions in the experimental farm of Razi University, Kermanshah in terms of agronomic and molecular traits. Eleven agronomic traits, including biological yield, grain yield, straw yield, harvest index, plant height, panicle length, number of panicles per m2, number of seed per panicle, thousand seed weight, days to 50% flowering and days to physiological maturity were measured. The results of the analysis of variance showed that there is a significant difference between the genotypes for all the investigated traits, which indicated the existence of high genetic diversity among the studied genotypes. Correlation coefficients showed that traits of biological yield, straw yield, harvest index, plant height, number of panicles per m2, number of seeds per panicle, and thousand seed weight had a positive and significant correlation with grain yield. Based on the results of path analysis, the number of seeds per panicle and then the number of panicles per m2 showed the most direct and positive effect. The biggest negative indirect effect on the grain yield was due to the number of panicles per m2 through the number of seeds per panicle. Cluster analysis based on the agronomic data using Ward's method grouped the genotypes into four clusters. The greatest genetic distance was observed between clusters 1 and 4. Based on the principal component analysis, 63% of the total variation was justified by the first two main components. Bi-plot obtained from principal component analysis confirmed the grouping results of cluster analysis. A molecular study was performed on 148 oat genotypes with independent pedigrees using 12 SCoT primers. A total of 135 bands were produced, of which 84 bands (61.75 %) were polymorphic. The highest values of the number of polymorphic bands, polymorphism percentage, marker index, effective polymorphism ratio, and resolution power were obtained for the SCoT1 primer, which can indicate the appropriate efficiency of this primer in differentiating oat genotypes. The genetic similarity of the studied genotypes varied from 0.32 to 0.87 using the Jaccard similarity coefficient. The highest genetic similarity was observed between genotypes 360 (DUNNART) and 361 (HOUDAN), and the lowest genetic similarity was calculated between genotypes 239 (WESTON) and 277 (STORMONT IRIS). Cluster analysis based on SCoT marker data, based on the UPGMA method and Jaccard similarity coefficient, divided oat genotypes into six groups. The results of the principal coordinate analysis confirmed the cluster analysis results. The study of the population structure showed the existence of three possible subpopulations (K = 3) for oat genotypes. The results of the association analysis based on the general linear model (GLM) and the mixed linear model (MLM) identified 111 and 38 significant relationships between genomic locations and studied traits, respectively. In total, the results obtained from the present study showed that there is a wide range of genetic diversity among oat genotypes, and it provides the possibility of using them in breeding programs. Also, It has been found that SCoT markers are useful and powerful tools for evaluating genetic diversity and identifying genomic regions related to the studied traits in oat genotypes. Therefore, they could be used in the selection of genotypes as parents for crossing and marker-assisted selection (MAS) to be used in plant breeding programs.

  Abstract:Aim:Seedling establishmentis one of the most important stages of crop cultivation.Using seeds with highvigor is a suitable way.From the past until now, the standard germination testis used as a primary test to determine the seed quality.But its result canrarely determine the seedling establishment in the field.If the farm conditionis far from the optimum, the obtained results in the laboratory and in thefield will show more difference.Today, to prevent this problem, seed vigortests are used.Studying the relationship between laboratory tests and seedlingestablishment in the field is one of the most important researches in the seedtechnology.The purpose of this study was to evaluate different seed vigor testsin the laboratory for oat varieties to predict the seedlings establishment inthe field and determine the most suitable test.Materials and methods:Inthis study, eight oat seed lots (belonging to four varieties new produced in2019 and old produced in 2012) were used.The research was conducted in thelaboratory and research farm of Razi University during 2019-21.In thelaboratory section, various seed vigor tests such as standard germination test,cold test, osmotic stress test, water imbibition test, electrical conductivitytest and accelerating aging test were performed on eight oat seed lots.In thefield section, the percentage and rate of seedling emergence were alsomeasured.Finally, the correlation among the results of the laboratory tests andthe field test were measured.Results:Oat seed lots weredifferent in terms of vigor.Among the seed lots, Qual and then Potoro varietieshad higher seed germination, seedling, vegetative and reproductive growth thanEuro and Tarahomara varieties.As the seeds aged, the amount of seed vigor decreasedsignificantly.Standard germination test, cold test, osmotic stress test,electrical conductivity test and water imbibition test were able to predict thepercentage and emergence of oat seedlings in the field.In the standardgermination test, the germination rate had the highest correlation with thepercentage and rate of seedling emergence in the field, but in the cold test,the highest correlation was obtained in the seedling vigor index of the normalseedlings.In the osmotic stress test, plumul length and seedling weight had thehighest correlation with the seedling emergence percentage; but radicle weightand seedling vigor index of the normal seedlings had the highest correlationwith the seedling emergence rate in the field.According to the correlationcoefficients in the electrical conductivity and the water imbibition tests,these tests were also able to predict the seed vigor in the field.Conclusion:Based on theresults of the experiment, the osmotic stress test and then the cold test are recommendedto determine the oat seed vigor and predict the seedling establishment in thefield.In other words, these tests have a high potential in separating strongand weak seeds.Keywords:Accelerated agingtest, cold test, electrical conductivity test, osmotic stress test, standardgermination test, water imbibition test.  

   In order to study the genetic diversity of 361 oat genotypes in terms of different agronomic and morphological traits, an experiment was conducted in the form of a square lattice design with two replications in 2019-2020 cropping year in the Research Farm of Razi University, Kermanshah. The results of analysis of variance showed the existence of diversity for all traits at the 1% probability level. The results of correlation coefficients for grain yield showed that this trait had a positive correlation with harvest index, number of   panicle per m2 , thousand grain weight, biological yield and hectoliter weight. In factor analysis, 76.05% of the data variations were justified by three factors. The results of stepwise regression analysis showed that76.2% of the variations in grain yield were justified by number of panicle per m2, thousand grain weight, number of grain per panicle, biological yield, days to physiological maturity, plant height and hectoliter weight. Based on the results of path analysis, biological yield followed by number of   grain per panicle and thousand grain weight had the most positive direct effect on grain yield, respectively. The most positive indirect effect on grain yield was shown by number of panicle per m2   throught day to physiological maturity. Cluster analysis divided the studied genotypes into ten groups. Based on the results of cluster analysis and the Selection Index of Ideal Genotype (SIIG), genotype number 285 (220-NMO-758) was recognized as a high-yield genotype among 361 studied genotypes.

   Abstract: In order to Evaluation of the factors affecting yield grain and herbages of 16 genotypes Vicia ervilia Under stre   and non-stress conditions, experiments in the research farm of Razi University of Kermanshah, in years 2016-2017 and 2017-2017 in tow Completely randomized block   design with three replications . Each year, diversity terms of morphological traits, yield and yield components. have been studied. The results of combined analysis of each year in both stre   and non-stress conditions as well as combined analysis of traits in two years in both conditions showed that the genotypes were significantly different from most of the studied traits. Based on the results of comparison of means, yield and yield components in all genotypes were reduced by applying water shortage stress in stress conditions and the percentage of reduction was not the same in all genotypes. The results showed that in the non-stress place of genotype 4 with the highest number of pods per plant, the number of seedlings per plant and 1000-seed weight had the highest grain yield (922.4 kg / ha) and in the dryland genotype 6 had the highest grain yield.According to the results of biplot chart in stre   and non-stress conditions, grain yield had a positive and high correlation with plant height, yield components, harvest index and negative correlation with the number of days to flowering. according to the results of Causal analysis in both years, in non-stress conditions, the number of seeds per plant and in stress conditions, biological yield had the most direct and positive effect By factor analysis, three factors were identified in both environments that explained 71.62 and 71.74% of the data diversity, respectively. Based on the evaluation of drought tolerance indices, stress intensity (SI) was equal to 0.34. Grain yield in non-stress conditions had a high correlation with SSI, TOL, MP, GMP and STI indices but grain yield in stress conditions showed a significant negative correlation with SSI and a positive correlation with GMP and STI. Therefore, due to the correlation of grain yield in both non-stre   and stress conditions with GMP and STI indices, these two were the best indices for selecting and determining drought tolerant cultivars for 16 Vicia ervilia genotypes. Genotype 15 with the highest value of these two indices was identified as a drought tolerant genotype in this study.

Evaluation of the plant growth promoting rhizobacteria (PGPR) role on alleviation of salinity stress in tomato(Solanum lycopersicum)

  The role of plant growth promoting rhizobacteria (PGPR) on reduction of drought stress in tomato (Solanum lycopersicum).

     In order to evaluate water deficit tolerance and genetic variation of 16 bitter vetch genotypes, two field experiments were conducted using randomized complete block design with three replications under non-stress and water deficit stress conditions at Research farm of Razi University, Kermanshah.   Days to flowering, days to maturity, grain filling period, plant height, number of branches, number of pods per plant, number of seeds per pod, number of seeds per plant, thousand seed weight, grain yield, biological yield and harvest index were measured in the both environments. Analysis of variance in each environment revealed significant variation among genotypes Combined variance analysis of the data showed that the effect of environment on most traits was significant. Different stress tolerance indices including stress susceptibility index (SSI), tolerance (TOL), geometric mean production (GMP), mean production (MP), stress tolerance index (STI), yield index (YI), yield stability index (YSI) and harmonic mean (HAM) were calculated based on yield data in the both coinditions. MP, GMP and STI indices showed positive significant correlation with yield in the both conditions, and YI and HAM indices were correlated with yield in stress conditions. Therefore, they were appropriate indices for selection of superior genotypes. Based on the biplot of the first two main components, genotypes 2, 3, 13 and 16 were identified as suitable entries for the both conditions. Genetic parameters were estimated for all the   measured traits. As a whole, phenotypic correlations were more than genetic correlations, indicating the effect of environment on the genotypes.Keywords: Genetic Diversity, Water Deficiency Stress, Bitter Vetch

In order to evaluate the effect of different seed priming methods and exogenous application (spraying) of some plant hormones on flower initiation and yield of pumpkin (cucurbita pepo L.). an experiment in educational and research farm of campus of Agriculture and Natural Resources of Razi University of Kermanshah/Iran as completely randomized design and complete block design respectively with four replications in 2013-2014 season were conduct. Priming treatments were include: sytokinin 100ppm, auxin 100ppm,   ilica at level 1mM, salicylic acid at level 1mM, hydro priming and control (non-priming). plant spraying were include: sytokinin 100ppm, auxin 100ppm, salicylic acid 1mM, and control (non-spring). The results showed interaction effects of priming and spraying had significant effect (p?%1) for all studied traits except 1000 seed weight. Also mean compare results showed that, when spraying by cytokinin accrue, priming by salicylic can increase yield and its components. Mean while during spraying by salicylic acid, priming by auxin can raise yield characters. In case of priming without spraying, using silica was more useful and increased yield and its components. For male and female flowers, priming by silica and spraying by auxin and salicylic acid produced more female flowers.  

  An experiment was conducted to evaluate callus induction and regeneration in some oat genotypes, in Plant Tissue Culture Lab, Agriculture and Natural Resources Campus, Razi University in 2013-2015. Experiments were callus induction on matured embryo and anther explants and indirect regeneration on matured embryo explant. Factorial experiment was conducted based on completely randomized design (CRD) with three replications. Callus induction experiment on matured embryo explant was applied on MS medium supplemented with different concentrations of NAA and 2,4-D (1, 2 and 4 mg/l) plus 0.1 mg/l kinetin with control medium (basal medium), and callus induction experiment on anther explant was tested on MS medium with two concentrations (0.5 and 1 mg/l) of 2,4-D plus 0.1 mg/l kinetin with control medium. In this study, the evaluated traits include days to callus induction (DCI) (just done for embryo culture experiment), callus induction percentage (CIP), callus diameter, callus growth rate (CGR) and Magoer rate (just done for embryo culture experiment). Indirect regeneration experiment was performed just for obtained callus of matured embryo. This experiment was tested on MS medium with different concentrations of BAP (1, 2 and 4 mg/l) on three different kinds of calli which obtained from 4mg/l NAA, 2mg/l 2,4-D and 4mg/l 2,4-D. Days to regeneration and regeneration percentage were evaluated traits. Results from callus induction on matured embryo showed that callus induction amounts will be increased with increasing amount of growth regulators. So that, a combination of Mortlock with 4mg/l 2,4-D had the highest amount of callus induction percentage (76.66%). In regeneration test, increasing of BAP caused increasing in responses, which in a treatment combination of Wintaroo, 13ZOP95,IA91098-2 and Brusher genotypes in 4mg/l BAP obtained from calli of 4mg/l NAA medium (with means of 100%), and a treatment combination of Tarahumara genotype in 4mg/l BAP obtained from calli of 4mg/l 2, 4-D medium (with mean of 100%) had the most amount of regeneration percentage. Results of cluster analysis showed that Swan,42ZOP95, Mortlock, Brusher and UFRGS948886 in a cluster had the highest amount of CIP and callus diameter and the lowest amount of DCI. According to callus induction on anther explant results, callus production has more depended to genotypes than growth regulators. For example, a treatment combination of Echidna genotype in 0.5mg/l 2,4-D had the highest CIP (with mean of 18.33%).
