Relationships of some Economically Important Traits with Storage Proteins in Common Bean (Phaseolus vulgaris L.)

In order to evaluate the genetic diversity of common bean (Phaseolus vulgaris L.) and the relationships between studied characteristics with seed storage proteins, 60 genotypes with three colors (white, red and pinto bean) were studied using an augmented design with three blocks and four varieties as controls. The majority of studied traits were significantly different between large and small seeded beans. Significant and positive correlations were observed between number of pods per plant, 100 weight and number of seeds per pod and grain yield. Seed storage proteins were prepared by consecutive extraction of salt soluble proteins and the proteins were separated by SDS-PAGE procedure and two different banding patterns were observed. Analysis of variance and multivariate method of Hoteling,s T2 test showed that there were significant differences between presence and absence of some proteins for 100 seed weight, number of seeds per pod and other characteristics of seed and pod. Cluster analysis, using UPGMA procedure, based on seed storage proteins banding pattern in 60 genotypes formed two groups. First group contained all genotypes of white and red beans except two genotypes and second group contained all genotypes of pinto bean with two genotypes of red bean.
