ABSTRACT
In present investigation, A wide range variation in estimates of heterobeltiosis and standard heterosis in positive and negative direction was observed for grain yield per plant. In case of grain yield per heterobeltiosis ranged from -26.87 (NDRK5096/F1) to 10.78 (IR2-9-B-1-5/F1) and standard heterosis varied from -22.18 (NDRK5096/F1) to 7.03 (IR2-9-B-1-5/F1) over SV1. NDRK 5026/Jaya, NDRK5026/CSR10, NDRK5026/F1, NDRK5096/F1, NDRK5088/F1, and CSRS (C) 52-1-1/F1 were found highly significant over standard variety SV2 (CSR10), while, NDRK5096/Jaya, NDRK5096/CSR10, NDRK5088/Jaya and NDRK5088/CSR10 were significant over SV2 for grain yield per plant.
Keywords: Heterosis and yield.
