Analysis of variance showed significant differences for all characters especially for grain yield performance. Indices of drought tolerance were calculated based on the yield under three environments in two cases. Principal component analysis in both case reduced five indices down two components. Correlation analysis among grain yield in three environments, indices and also biplot analysis, revealed that GMP, MP and STI are the superior criteria for selection of high yielding genotypes. Kohdasht, Nestor and Maroon genotypes with less grain yield fluctuation in three condition were introduced as drought tolerant genotypes.

Result of analysis of variance indicated that there were significant differences among the genotypes in the majority of traits. The results of correlation analysis showed that grain yield had positive and significant simple correlation with number spike per square meter, harvest index, biological and straw yield, and negative correlation with spike length and awn length. The highest positive correlation was obtained between biological yield and grain yield. Using stepwise regression, 1000 kernel weight, number of spike per square meter, kernel per spike and harvest index was the most important yield component. Path analysis for grain yield showed that the number of spike per square meter and harvest index had positive direct effect on grain yield.

Genetic diversity of 40 wheat genotypes was assessed using 30 SSR primers that all of them were generated scorable bands. Totally 71 alleles (ranged between 2 to 4 alleles per each locus) was distinguished. Polymorphic information content (PIC) for all SSR primers was calculated. The highest (0.77) and the lowest (0.13) value of PIC was pertained to Xbarc352 and Xcfd56 Primers, respectively. According to similarity matrix, genetic similarity value ranged from 0.18 to 0.95 with an average of 0.48. The lowest and highest genetic similarity was observed between the Sistan and Arg (Bread wheat, No 27 and 28), Karkheh and Behrang (Durum wheat, No 35 and 38) genotypes respectively. Unweighted pair group method of the arithmetic average (UPGMA), based on Jaccard similarity clustering form a dendrogram with three genotypes group. Clustering somewhat was distinguished durum and bread wheat's. Principle co-ordinate Analysis (PCA), 2D plot was confirmed the results of cluster analysis. Cophenetic correlation showed that molecular data and cluster was corresponded. It was concluded that SSR marker was suitable for evaluated of genetic diversity in wheat genotypes and this genetic diversity can be used in wheat breeding programs.
