An investigation was carried out to study the frequency distribution, variability parameters and character association of traits in F2 populations of rice from the cross BPT-5204 x WAB 450 for grain yield and its component characters. In general, the PCV was higher than the GCV for all the traits and small differences between PCV and GCV were recorded for morphological traits studied which indicates less influence of environment on these characters. | Genetic variability character association frequency and normality distribution studies for F2 population of BPT-5204 x WAB-450 cross in rice Oryza sativa L.
