Abstract
Twenty-eight pigeonpea hybrids resulting from 8 × 8 diallel mating design excluding reciprocal were evaluated in randomized block design with three replications for twelve different characters to study the magnitude of heterosis. The heterosis over mid parent, better parent and standard check were ranged from-38.05 to 33.02 per cent, -54.05 to 27.61 per cent and -48.50 to 13.75 per cent respectively, for seed yield per plant. Three cross combinations viz., UPAS-120 × GT-103, BSMR-853 × Banas and BSMR-853 × GT-1 showed significant and desirable heterosis for seed yield per plant over mid parent and two hybrids viz., BSMR-853 ×Banas and BSMR-853 × GT-1 showed significant and desirable heterosis for seed yield per plant over better parent. The best hybrids with significant positive heterosis over standard check were ICPL-87119 × GT-103 (13.75) and ICPL-87119 × AGT-2 (13.48). The best crosses selected on the basis of perse performance and heterosis for seed yield per plant were ICPL-87119 × GT-103 and ICPL-87119 × AGT-2 which could be utilized for their large-scale testing and general adaptability.
