Abstract

This research was conducted to study yield and yield component of 20 rice genotypes. The genetic material of the genotypes was used to measure days to 50% flowering, days to maturity, panicle number/plant, panicle length (cm), number of mature seeds/panicle, number of empty seeds/panicle, grain yield/plant, 1000 seed wt. (gm) and grain yield (t/ha). The results revealed highly significant differences in 2016 for most parameters, significant difference in plant height after 30 and 60 days, leaf area and panicle length but not significant for plant dry weight. The results of 2017 showed similar trend with significant differences in plant height at 30 days, tillers of 90 days and not significant for plant dry weight. The significant yielding genotypes were NERICA 14 (12.30 t/ha) and NERICA4 (7.30 t/ha) in 2016. In 2017, SR 14 (10.42 t/ha) and NERICA 14 (7.00 t/ha) gave the best significant yield. However, for combine analysis SR 14 (8.01 t/ha) and NERICA 14 (9.60 t/ha) were the best.
