Abstract:

Genetic parameters, variability, heritability and genetic advance were studied among 20 groundnut cultures rabi-2016-17 to study the variation and to identify traits of high heritability. The characters hundred kernel weight, hundred pod weight, dry pod yield and kernel yield had high GCV, heritability and GAM were found to be under the control of additive gene action, while the traits shelling percentage, sound mature kernel and final plant stand with moderate heritability and high genetic advance appeared to be under the predominant influence of additive gene action. Low GCV were recorded for days to fifty per cent flowering and duration of maturity. Correlation studies indicated that the characters, 100 seed weight (g), hundred pod weight (g), pod yield and kernel yield should be given major emphasis for the development of high yielding genotypes.
