CONVENTIONAL BREEDING ENHANCES GENETIC DIVERSITY IN PISUM SATIVUM L DETECTED THROUGH SDS PAGE
In the present study, twenty homozygous segregante of edible pea were developed through conventional breeding (20042015) The seed storage proteins were extracted from the seeds of each line and run through Slab vertical gel Electrophoresis. After staining and de staining the Electrophoregram was divided into two zones (R I and R II) The R 1 was consists of five bands (B 1, 2, 3, 4 5) ranging from 180KDa to 34KDa, which calculated 1% genetic diversity (GD) Out of which B 1, 2 and 3 were polymorphic, while B 4 and B 5 were monomorphic. Due to strong genetic association and low level of GD, the R I divided the total germplasm into two clusters. Similarly, R II was comprised of nine bands ranging from 33KDa 10KDa. All the loci were polymorphic and showed >39% genetic diversity. The R II divided the total lines into four clusters. In cluster plating, 43.74% lines were grouped in C 03, 30.43% in C 01, 13.39% in C 04 and 8.69% in C 02. Variation in bands profile and multiple clustering authenticates that conventional plant breeding enhances the level of genetic variation in seed storage protein profile in pea germplasm detected through SDS PAGE.
