Correlation and Path Analysis of Yield and yield Attributes in Local Rice Cultivars (Oryza sativa L.)

The associations among the yield components and direct and indirect influence of yield components on the grain yield of local rice were investigated at Agricultural college farm, Navile, Shimoga. The experiment was laid out in a 10 x 10 Simple Lattice Design with two replications which consisted of 100 local genotypes during Kharif 2010. The correlation analysis indicated that grain yield was significantly associated with panicle length, test weight, number of tiller per plant, number of productive tiller per plant, number of spikelet per panicle, per cent spikelet fertility and amylase per cent. Path coefficient analysis revealed that days to 50% flowering, plant height, panicle length, panicle number, number of productive tiller per plant, per cent spikelet fertility and amylase per cent had positive direct effect on grain yield. Hence, selection on these traits could be suggested to bring simultaneous improvement of yield and yield attributes.
