Identification of heterotic hybrids for seed yield and its attributing traits in pigeonpea

Heterosis for seed yield and its components were estimated in 40 crosses obtained by crossing 4 female lines with ten male testers in LXT fashion. BSMR-736 and ICPH-2671 were used as standard checks. The analysis of variance revealed significant differences among the parents and hybrids for all the characters studied. Non-additive gene effects were predominant for all the characters, except for days to 50% flowering. The crosses ICPL-3406 x BSMR-23, ICPL-20106 x ICPR-3477, ICPL-3450 x AKT-9913 were best crosses showed high heterosis over mid parents and better parent for grain yield/plant respectively, with 144.98 and 61.31 over the standard check BSMR-736 and ICPH-2671 respectively for grain yield plant.
