All possible crosses excluding reciprocals were made among 10 diverse genotypes of field and table pea. General and specific combining ability variances were significant for all the traits in both F1 and F2 generations. Higher values of variance due to gca for days to flowering, days to maturity, plant height, pod length, number of developed ovules per pod, shelling percentage and green pod yield per plant showed presence of additive gene action while it was non additive for number of productive branches per plant and number of pods per plant based on both the generations. Parents ‘KS-226’, ‘KS-225’, ‘KS-136’, ‘Azad P-1’ and ‘Azad P-3’ were good general combiners for green pod yield based on both the generations. The average performance of table pea parents were better than field pea parents. Cross combinations namely ‘KPMR-184 × KS-136’, ‘Rachna × KS- 225’, ‘KS-195 × AP-3’, ‘KPMR-184 × Mutant pea’ and ‘Mutant × KS-136’ in F1, ‘KS-195 × KS-225’, ‘KPMR-184 × AP-3’, ‘Mutant × KS-226’, ‘KS-226 × AP-1’ and ‘KPMR-65 × KS-226’ in F2 were found as good specific combinations for green pod yield. The majority of these crosses falls in the high x low general combiners. The crosses between table x field pea gave higher yield than table x table or field x field pea.
