Özet
This research was carried out to investigation the genetic structure of the 24 F-1 pea hybrids established from eight exotic female lines and three local winter hardiness male testers, to determine parents showing general combining ability (GCA) and determine crosses showing specific combining ability (SCA.), and to evaluate the heterosis. 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 PS9830S329 (female) and H (male) were the best general combiners among the parents, PS9830S329 x B-12 was the best cross for seed yield. Hybrids generally showed greater yield potential than their parental genotypes. Heterosis was observed in some hybrids for each trait studied.
