Comprehensive Multivariate Analysis Of Rice (Oryza Sativa L.) Genotypes Of Tamil Nadu For Yield And Yield Attributed Traits
Main Article Content
Abstract
An experiment was performed to assess the variability parameters for biometrical traits in 104 rice genotypes. Higher estimates of GCV and PCV were found for single plant yield and filled grains per panicle along with high heritability and genetic advance. Single plant yield exhibited significant positive genotypic correlation for most of the yield contributing characters like number of productive tillers, number of filled grains per panicle, number of tillers, panicle length and thousand grain weight. The highest positive direct effects on yield were exhibited by number of filled grains per panicle followed by number of productive tillers at genotypic level for the improvement of rice yield. Estimates of genetic variability analysis exhibited, single plant yield and number of filled grains per panicle are positive for practically all variability factors tested. The study revealed high genetic variability, indicating that the genotypes could be utilized for further rice breeding.
