CORRELATION AND PATH COEFFICIENT ANALYSIS OF YIELD AND YIELD CONTRIBUTING TRAITS IN RICE (Pages : 1 - 6)

Studies on character association and path-coefficient analysis were conducted on ten rice genotypes including seven landraces and three released variety for their yield and yield contributing traits. Character association of the yield attributing traits revealed significantly positive association of yield panicle-1 with days to 50% flowering, days to maturity, plant height and number of filled grains panicle-1. Hence, selection for these traits can improve yield. Path coefficient analysis revealed that Days to maturity, number of filled grains panicle-1, number of unfilled grains panicle-1, and 1000 grains weight exhibited direct positive effect on yield panicle-1 at genotypic level and days to 50% flowering, plant height, panicle length, number of effective tillers plant-1, percent fertility exhibited direct positive effect on yield panicle-1 at phenotypic level. Hence, selection for this character could bring improvement in yield and yield components. This study revealed that genetic improvement of yield in rice is admissible by selecting characters having high positive correlation and positive direct effect on grain yield.Download
