Correlation and path analyses of yield and its component characters in scented rice
Correlation and path analyses were studied for grain yield, its components and quality characters in a set of 65 genotypes of scented rice. A very strong positive correlation of grain yield plant-1 at genotypic, phenotypic and environmental levels was observed with harvest-index, while number of effective tillers plant-1 and biological yield plant-1 showed very strong positive association at both phenotypic and genotypic level. Harvest-index followed by number of effective tillers plant-1, biological yield plant-1, kernel length, L/B ratio, fertility percentage and 1000-grain weight emerged as the most important associate of grain yield in scented rice. Path analysis identified biological yield plant-1 and harvest-index as major direct contributors and number of effective tillers plant-1, days to 50% flowering and days to maturity as main indirect contributors
