Estimation of Genetic Variability, Direct and Indirect Effects of Yield Contributing Characters on Grain Yield of Upland Rice (Oryza sativa L.) Germplasm

A study was carried out using 24 upland rice genotypes grown in randomized block design with three replications to estimate genetic variability, correlation and path coefficient analysis. Based on the mean performance, of high grain yield per hill, genotype SHUATS UPR-13 followed by UPR-11 were identified be superior. High phenotypic genotypic variation observed for biological hill number panicles hill. heritability coupled advance as percent tillers indicating that present material studied is probably due additive variance, which can effectively exploited crop improvement programme. The traits plant height, harvest index found have positive significant association at both level. Hence, selection these shall help selecting Number panicle length, had positively direct effect Therefore, effective must attempted would suitable different environments.
