Abstract

The results were indicated that, out of sixty 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.
