In order to achieve more high- yielding chickpea genotypes than the existing cultivars that have suitable traits such as seed yield, more number of pods per plant, coarseness of seeds , early maturity and other desired agricultural traits, 16 advanced chickpea genotypes selected from advanced tests comparing crop year yield 2015-2016 along with Adel and Azad witness figures for three crop years (2016-2019) in Gachsaran, Gonbad, Khoramabad and Ilam were planted in the form of a completerandomized block design with three replications. Composite variance analysis showed a significant effect of genotype, environment and genotype interaction in the environment (GEI)., Therefore, Biplot method was used to analyze the genotype × environment interaction. The first two principal components explained 32/50 percent (26.12 and 24.2%, respectively) of the total GEI changes. The polygon view of Biplot showed that genotypes 18, 9, 17 and 16 with higher than average performance and near the origin of Bioplate were genotypes with high general stablity. Also genotypes 5, 12 and 11 showed adaptation to many environments. The average tester view of Biplot also showed that genotypes 12, 18 and 9 were the closest genotypes to the ATC axis and therefore the most stable and also had high average yield in different environments. The ideal genotype view of Biplot showed that genotypes 5 and 12 at the closest distance from the Biplot origin were the best genotypes and genotypes 1, 2 and 13 were the most unfavorable genotypes in terms of seed stability and yield.According to the results, genotypes 5, 9, 12 and 16 were selected as promising genotypes and candidates for introduction.

Co-inoculation of plant growth promoting bacteria and biological control agents, is a strategy to improve health, yield and quality of crop production. The objective of the present study was to evaluate interactions of two bacterial strains, Bacillus amyloliquefaciens UTB96 and Azospirillum oryzae NBT506, on growth promotion of wheat and control of the causal agent of Fusarium head blight, Fusarium graminearum. The results showed that single and co-culture of these strains inhibit mycelium growth of F. graminearum by direct inhibition and volatile organic compounds. In germinator assays, different wheat growth features were increased and disease index was decreased. Results showed that co-inoculation or single application of the bacteria in the soil significantly enhanced root length (14-80%), root fresh weight (18-167%), root dry weight (4-110%,), shoot length (17-61%), shoot fresh weight (47-169%) and shoot dry weight (up to 90%). In addition, a significant decrease in disease index (62-100%) was observed in different single and co-culture treatments. In conclusion, the studied two bacterial strains showed synergistic effects on wheat growth promotion and fungal growth inhibition.
