Abstract

Correlation and path coefficients analyses among seven morphological characters were studied in 24 rice genotypes at Rampur, Chitwan, Nepal during rainy season in 2017 and 2018. The experiment was carried out in randomized complete block design with three replications. Grain yield was negatively and significantly correlated with 50% flowering days, whereas only positively correlated with 1000-grain weight, fertility rate and panicle length. Path coefficient analysis revealed highest positive direct effect of 1000-grain weight on grain yield followed by panicle length and fertility per cent. Thus, 1000-grain weight could be used in genotype selection for crop improvement.
