Abstract: Heterotic performance of fifty one F1s and their 20 parents were evaluated in randomized complete block design with three replications. Significant differences were observed among parents, hybrids and hybrids versus parents for most of the yield and yield related characters. On the basis of SCA effects, crosses UPRI 2008-6 × Pant Dhan 23, UPRI 2012-10 × Pant Dhan 26, Kharif 2011-SNo-1423 × Pant Dhan 26, Kharif 2015-SNo-1414 × Pant Dhan 4, Pant Dhan 18 × Pant Dhan 23 showed significant standard heterosis for various traits. These crosses can be included in future breeding programme to achieve better heterotic output for grain yield and most of the quality traits. For grain yield per plant, Kharif 2015-SNo-1414×Pant Dhan 4 (16.608) exhibited highly significant positive standard heterosis over Govind (339.177) and Pant Dhan 4 (145.226) having Good × Poor gca effect of parents followed by Kharif 2011-SNo-1423×Pant Dhan 26 (13.348) with significant standard heterosis over Govind (316.463) and Pant Dhan 4 (132.543) having Good × Good gca effects of parents. Both the crosses exhibited high F₁ mean (72.170) and (68.437), respectively.
