ANALYSIS OF GENETIC VARIETY AND PHENOTYPE CLASSIFICATION OF BEANS (PHASEOLUS VULGARIS L.) UNDER DROUGHT STRESSSaeid Bakhtiari, Mohammad Reza Bihamta, Islam Majidi Herawan, Farrokh Darvish
An experiment was conducted in order to determine the genetic variability and relationships of common bean at drought condition. Two complete randomized designs with three replications carried out in ordinary and stressed water conditions separately. Factor analysis showed that in drought condition, 4 factors controlled more than %73.043 of data variations. The first and second factors which controlled more than %50.606 of variations were included pod width, 100 seed weight, seed width, seed length, number of pod, pod length, pod weight and seed yield per plant. These two factors recognized as yield and yield components factors. Genotypes 4, 8,10, 13,14, 22,23, 27, 30, 31,32,33, 35,36,37,38,39,41,42,43 and 45identified as drought tolerant genotypes. Cluster analysis of morphological traits, classified genotypes in 4 groups. The first and forth groups of genotypes showed the highest yield and yield components. Most of genotypes in these two groups selected by scatter plots of bi-plot analysis. Cluster analysis showed that crossing between genotypes from group one and four results in high yield hybrids.
