Abstract

A field experiment was conducted at Agricultural Research Station Mughad, for screening of 11 rice hybrids, in comparison with local check, under modified method of System of Rice Intensification (SRI). All hybrids showed significant difference for specific yield attributing characters. Among them MGD101 showed highest plant height (80.13cm), GK-5003 took less number of days to 50% flowering, Sahyadri-4 recorded highest number of total tillers per plant (22.25), while GK-5003 recorded highest Productive tillers (19.37), Panicle Length (23.45cm), Panicle weight (4.00g), Seed weight per plant (33.96g), Higher 1000 seed weight (24.68 g),Total Number of spikelet's (189.17),Number of filled spikelet's (166.14).Lower unfilled spikelet (34.57),Grain yield (2923.16 g/plot and 9.74 t/ha).
