Distribution pattern of segregants and heritability estimates in paddy (Oryza sativa L.) crop for 12 quantitative traits in two F2 populations derived from the cross AD 16019 x ADT43 and AD16019 x WGL 14377 was studied at TRRI, Aduthurai during 2016-18. Platykurtic symmetrical curve for the traits with positive skewness was registered for the traits 1000 grain weight and single plant yield. | Variability and heritability analysis for yield and grain quality attributes in F2 intervarietal populations of rice
