ABSTRACT
Forty eight rice hybrids of different parents were studied for correlation and path analysis at IIRR, Hyderabad.A critical analysis of both correlation coefficients and path analysis together for grain yield and its components indicated that, panicle weight, number of productive tillers per plant, numbers of filled grains per panicle and 1000 grain weight were more important in rice productivity. Other important traits to be considered for high grain yield was panicle length, number of total tillers per plant, as there always existed a significant desirable association between this trait and number of grains per panicle. Apart from these, spikelet fertility (%) and 1000 grain weight also exhibited positive direct effects on grain yield per plant.
Key words: Correlation, Pathanalysis, Hybridrice.
