Genetic Variability and Association of Yield Attributing Characters with Grain Yield in Deepwater Rice

A study on genetic variability and association of yield attributing characters with grain yield was carried out using 35 deepwater rice genotypes. High genotypic co-efficient of variation (GCV) was observed for plot yield, EBT/m2 , plant height and days to 50~% flowering (DFF). For all the traits, e...

Summary:A study on genetic variability and association of yield attributing characters with grain yield was carried out using 35 deepwater rice genotypes. High genotypic co-efficient of variation (GCV) was observed for plot yield, EBT/m2 , plant height and days to 50~% flowering (DFF). For all the traits, estimates of the phenotypic co-efficient of variation (PCV) were higher than GCV, indicating presence of environmental influence. High heritability and genetic advance was observed for plot yield, EBT/m2 and plant height. Plot yield had significant positive association with test weight, EBT/m2 and DFF. However, test weight had the maximum direct effect on grain yield
