Abstract :

Knowledge of genetic diversity and relationships between genotypes is mainly important for selection of parental genotypes. Moreover, assessing diversity across and within crop varieties is important to improve the description of collections in gene banks and in on-farm conservation practices. In order to evaluation and study of genetic diversity in the bean in normal condition, forty-five bean genotypes (15 genotypes of each white, red and chiti beans) were planted in a randomized group balanced block design with three replications under the non-stress condition and Twenty-four traits were recorded. The results showed that traits such as R7 (the number of days to stage podding), Bush type, 100 seed weight, bush height, height of internodes and steam diameter in white, red and chiti bean were significantly different (p<0.01). Furthermore, in the number of days to appearance of first three leaves let, pod/plant, seed/pod and seed/plant there were significant differences (p<0.05). According to simple correlation analysis of traits, the yield had a positive and significant correlation (p<0.01) with the length of the highest pod (r= 0.93). Moreover, in p
