Correlation and Path Coefficient Analysis Studies in Rice Hybrids (Oryza sativa L.)

The present investigation was carried out at Agricultural Polytechnic, Polasa, Jagtial, Telangana, to understand the correlation and path analysis for yield attributing traits 38 genotypes including 3 checks in Randomized Block Design replicated thrice during Rabi, 2022. Association studies revealed that genotypic values were higher than of phenotypic correlations. Important i.e., spikelet fertility (0.8151**/0.8199) followed by 1000 grain weight (0.7889**/0.7956) exhibited highest positive significant association with single plant yield. Path coefficient also had reported direct effect on both levels. Hence, these could be used as selection indices heterotic rice hybrid development.
