A study was carried out to estimate the general and specific combining abilities, as well as heterosis for seed yield and yield associated traits in pea lines.
Twenty-eight cross combinations were generated using half-diallel mating design with eight parental lines. The mean values of seed yield and its contributing traits of parental lines and their offspring for each replication were used for statistical analysis viz., GCA, SCA and Heterosis.
The GCA and SCA were significant and indicating the presence of both additive and non-additive types of gene actions. AP-3, VL-7, Kashi_Nandini and PC-531 were identified as promising parents due to significant GCA effects on seed yield and other traits. Among the crosses Kashi_Nandini × PC-531, VL-7 × PMR-53, Arkel × Vl-7 and VL-7 × Kashi_uday hybrids were the most promising, with significantly higher SCA effects for seed yield and yield related traits. Seed yield showed significantly high heterosis ranged from -2.00% to 8.77% (AP-3 × PC-531 and Arkel × PMR-53, respectively) and relative heterosis ranged from -0.75% to 14.10% (Kashi_uday × PC-531 and Arkel × PMR-53 respectively) significantly exhibited positive heterosis for seed yield over better parent and mid-parent.
