Abstract/Description: | It is imperative to know the degree and direction of hybrid vigour of a cross for its commercial exploitation. Experiment was conducted to study heterosis for different morphological traits i.e. days to 50% flowering, plant height, ear bearing tillers, panicle length, total dry matter production, harvest index, sterility, plot yield under drought stress condition with Randomized Block Design (RBD) at Central Rice Research Institute, Cuttack in 2012. Grain yield, manifested highly significant heterobeltiosis and standard heterosis in ten and thirteen crosses respectively. The highest heterotic effect among the yield components were observed for total dry matter, harvest index, panicle length and tiller number. The following crosses Mahulata x Ratna, Mahulata x Dandi, Mahulata x Swarna, Mahulata x Sahbhagi, Mahulata x Abhishek, Mahulata x Annada, Mahulata x IR 20, M55419-04 x Sahbhagi, M55419-04 x MTU 1010 showed positive significant in mid parent heterosis, heterobeltiosis and standard heterosis under water stress condition. Therefore, these crosses may be exploited for hybrid rice production and furtherit concluded that, our recent germplasm has great potential for developing new rice varieties for moisture stress condition. |
