Seed Storage Protein Profile of Rice Varieties Commonly Grown in Pakistan

Abstract

Present research was aimed at studying seed storage protein profi les of eleven released varieties / genotypes of rice (Oryza sativa) in Pakistan using SDS-PAGE analysis. Lower - medium level of genetic polymorphism (G.D. = 0 - 0.8) was estimated in the material. Six comparisons sh owed co mplete homozygosity (G.D. = 0%) for seed storage protein profile while one comparison (Basmathi - 385 - Local rice from Swat) s howed maximum gene tic di fference (G.D. = 80%). Re maining comparisons showed varying degree of genetic differences ranging from 20-70%.
