Abstract:
The results were indicated that, out of 60 crosses, the most desirable five crosses showing high significant positive heterosis over better parent for grain yield per plant were IR 79156A X NDR 370132 (72.19%), IR 68888A X NDR 370132 (66.69%), IR 68897A X NDR 370131 (43.33%), IR 58025A X CR 2499 (40.71%) and IR 79156A X NDR 2701 (35.80%). Eighteen crosses showed positive and significant heterosis over standard variety and the best five crosses among them were IR 58025A X NDR 1127 (20.78%), IR 79156A X IR 27723 (14.87%), IR 68888A X IR 27723 (14.81%), IR 58025A X Sugandha 5 (12.84%) and IR 68897A X NDR 2701 (12.46%). The cross, IR 58025A X NDR 1127, showed highest mean performance (28.70g), heterobeltiosis (22.48%) and standard heterosis (20.78%) for grain yield per plant while highest yielding parent, NDR-359, produced mean grain yield 23.78 g.
