Abstract

An experiment was conducted to evaluate heterosis for seed yield and its components in pigeon pea. Twelve parents and 35 F1’ s produced from Line x Tester mating design in randomized block design were evaluated for for thirteen quantitative characters. All the crosses showed positive heterosis over mid parent and better parent for seed yield per plant showed by crosses positively significant for mid-parent heterosis observed for ICP7376 X ICPL 87119 followed ICP7376 X ICPL-87, ICP7382 X UPAS-120, ICP7406 X UPAS- 120, ICP7382 X ICPL-87, ICP7004 X JKM-189, ICP7406 X JKM-189 and 12.26 ICP7406 X ICPL 87119. The significant positive heterobeltiosis were observed for seed yield per plant for crosses ICP7382 X UPAS-120 and ICP7004 X JKM-189. The hybrids showed heterosis for one or more yield related traits indicated that hybrid vigour in small magnitude for any one yield component may have additive effects on seed yield. The parents with good cross value could be further used in the future hybridization programmes.
