Abstract
In this study 55 promising rice varieties cultivated in Tamil Nadu was selected and raised in Randomized Block design with two replications. To reveal the nature and degree of correlation and path analysis between yield and quality traits. The results of correlation analysis showed traits like number of filled grains per panicle, productive tillers per plant had positive significant association with the single plant yield. The direct and indirect effects through path coefficient analysis unveils maximum positive direct effect of single plant yield with number of productive tillers recorded followed by days to fifty percent flowering, number of filled grains, gel consistency, 1000 grain weight and hulling percentage in both genotypical and phenotypical path analysis Therefore, the trait number of productive tillers per plant plays a major role in shaping the single plant yield in rice on which selection pressure has to be applied for increasing the seed yield.
