Abstract
Yield contributing traits in thirty three rice genotypes were studied for variances, heritability, correlation (genotypic and phenotypic) and path coefficient analysis. The highest phenotypic variation (σ2p), was found for No. of grain per panicle and the lowest was observed in 100 grain wt. High genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) for No. of unfilled grains per panicle, No. of grains per panicle and grains yield per hill, indicated that selection of these traits would be effective. The high heritability estimates along with low genetic advance indicates that non-additive type of gene action and genotype-environment interaction plays a significant role in the expression of the traits as observed in days to 50% flowering, No. of tillers per hill days to harvesting and panicle length (cm). No. of grains per panicle with grains yield per hill as well as length showed significant and positive correlation but No. of tillers per hill showed highly significant and negative correlation with days to 50% flowering both at genotypic and phenotypic level. Path coefficient analysis showed that No. of grains per panicle had maximum direct effect on grain yield followed by No. of panicles per hill, and No. of tillers per hill. The lowest direct effect on grain yield was exhibited by No. of unfilled grains (0.0732) followed by plant height, No. of primary branches per panicles, and No. of secondary branches per panicles respectively. Number of grains per panicle had maximum direct effect on grain yield followed by No. of panicles per hill and No. of tillers per hill. The results prescribed that there is a highly significant positive correlation with positive direct effect was observed in No. of grains per panicle, No. of panicles per hill, No. of unfilled grains per panicle, No. of primary branches and No. of secondary branches.
Key Words: Genetic variability, heritability, character association and path coefficient analysis
