Abstract:
Genetic parameters for 15 metric characters in 80 divergent varieties of groundnut
grown in the summer rice fallows were estimated. The varieties differed significantly in
respect of all the characters. The pcv was higher than gcv for all the characters. High
estimates of gcv, heritability and genetic advance were obtained for number of branches,
flowers and leaves, spread of flowering and 100 pod weight whereas the values were low
for fresh weight of pods and dry pod yield. So also the high pcv for dry pod yield suggests
that the genetic improvement for the economic trait through selection for summer rice fallows
is meagre. Oil content, shelling percentage and duration up to flowering and maturity
registered high heritability, but low genetic advance.
