Magnitude of heterosis in some inter - Varietal crosses of Rice (Oryza sativa L.)

Author(s): Bineeta Devi
Abstract: Heterosis in rice was studied in a set of seven line and three testers with twenty one hybrids. The magnitude of heterosis varied from cross to cross for all the quantitative traits using L x T analysis. Among the parents, M1-10-29VL and TM07280 were the best performing parents for seed yield per plant and its components traits. Cross combinations IR777629-72-2-1-3 X IR64, Basmati 370 X CR2703, Sonam X NDR118 and IR7734-4-0 X CR2703 exhibited high significant effects with high per se performance and standard heterosis over PHB71. High magnitude of heterobltiosis and standard heterosis were observed for almost all characters. Cross combinations M1-10-29 VL X NDR118, Basmati 370 X CR2703, TM07280 X NDR118, IR77629 -72-2-1-3 X IR-64 and TM07280 X IR-64 exhibited highly significant heterosis over PHB71.
