Abstract

Twenty eight crosses combinations were developed by 8 × 8 diallel analysis during rabi 2007–08 and evaluated 28 F1’s and 8 parents during rabi 2008–09 under late sown condition. Seven crosses out of 28 crosses manifested significant positive heterobeltiosis for grain yield per plant. The range of heterobeltiosis for grain yield was wide (22.30% to 82.54%). The hybrid GW 02–51 × VDW 99–176 (82.54%) expressed the highest heterobeltiosis. The cross combination GW 1139 × GW 1240 expressed highest level of heterosis over better parent (10.78%) for grain protein.
