Abstract:

Experiment was conducted to study heterosis for different morphological traits i.e. days to fifty per cent flowering (DFF), plant height (PH), chlorophyll content (CC), tillers per plant (TPP), relative water content (RWC), panicle length (PL), grains per panicle (GPP), 1000 grain weight (1000-GW), harvest index (HI) and yield per plant (GYP) under drought conditions with Randomized Block Design (RBD) at DRPCAU, Pusa Samastipur Bihar in 2016 Our results indicates that the maximum standard heterosis under drought condition i.e. 119.05% was recorded in (P2 X P8) for tillers per plant followed by 109.86% in (P4 x P10) for grain yield per plant, 73.53% in (P4 x P10) for grains perpanicle, 39.92% in (P3 x P7) for chlorophyll content, 27.72% in (P1 x P2) for harvest index, 27.08% in (P3 x P5) for 1000- grain weight, 24.40% in (P3 x P6) for panicle length and 10.78% in (P1 x P3) for relative water content. Some hybrids had good heterosis for specific traits such as tillers per plant, 1000 grain weight and yield per plant that can be used for the development of new hybrid rice varieties. It can be concluded that our recent genotype has great potential that can be used for development of new varieties.
