Relationship Between Storage Protein Patterns with Agronomic and Morphological Characters in Common Bean (Phaeolus vulgaris)

In order to study the relationship of protein diversity with morphological and agronomic traits in Phaseolus vulgaris, 70 genotypes were evaluated. Samples of seed proteins were prepared by two consecutive extractions of 0.2 and 1 M NaCl of salt soluble proteins. Most of the genotypes showed two different protein patterns. Hotteling T2 for comparison of two groups with or without a special band based on agronomic and seed morphological characters showed significant differences for some protein bands. In low salt soluble proteins (0.2 M), genotypes having bands with the Rf of 7, 38 and 40 had higher 100 seed weight whereas genotypes with the bands of 38 and 40 had lowerseed numbers in comparison with genotypes presented Rf of 30 and 32. In high salt soluble proteins(1 M), 54% of genotypes had bands with Rf of 8, 24 and 26 and 46% with the Rf of 7 and 30. In his test, genotypes with lower 100 seed weight and higher number of seeds and pods per plant, had bands with the RF of 8, 24 and 26 and 7 with the RF of and 30 were associated with the genotypes having higher 100 seed weight and lower seed and pod number per plant. The largest difference between the two protein patterns were obtained for 100 seed weight which seems this charactercorresponds to the identification of two centers of diversity for P. vulgaris.
