ABSTRACT
Eighty diverse genotypes of bunch groundnut were evaluated during summer 2006 for genetic
parameters viz., variability, heritability and genetic advance. The estimates of PCV and GCV
were high for number of secondary branches per plant and number of aerial pegs per plant. High
heritability along with high genetic advance as per cent of mean was observed for number of
secondary branches per plant and number of aerial pegs per plant indicating that these traits are
mainly governed by additive gene action and responsive to selection for further improvement of
these triats.
