This research was carried out to investigation the genetic structure of the 36 F1 garden pea hybrids established from 12 female parents (Line) and three male parents (Tester), to determine parents showing general combining ability (GCA) and determine crosses showing specific combining ability (SCA). Broad genetic variability was observed among the genotypes. Estimates of variance due to GCA and SCA and their ratio revealed predominantly non-additive gene effects for all studied traits. While line KS-156 and KS-256 were the best general combiners among the parents, KS-175 X E-6 was the best cross for seed yield. Hybrids generally showed grater yield potential than their parental genotypes.
