Correlation and path analysis carried out using 48 genotypes of rice for grain yield its components and quality characters revealed that grain yield exhibited significant positive correlation with grains/panicle, spikelets/panicle and effective tillers/plant at maturity at both phenotypic and genotypic levels. Total tillers/plant had correlation with grain yield/plant at phenotypic level only. Significant negative genotypic correlation with days to 50 per cent flowering and days to maturity revealed that early maturing genotypes yielded high under Palampur condition. Highest positive direct effect of grain length on grain yield, followed by effective tillers/plant at maturity, grains/panicle, protein content, plant height at maturity, amylose content and days to maturity at genotypic level was observed whereas length:breadth ratio had a negative direct effect.
