Genetic variability, frequency distribution and association analysis in ADT (R) 48 x Kavuni derived F2 population of rice (Oryza sativa L.)

The current research was aimed for estimation of variability parameters, heritability, genetic advance, skewness, kurtosis, association and path coefficient analysis for twelve traits using F2 population attained from the cross ADT (R) 48 x Kavuni. High GCV and PCV, higher range of heritability adjo...
