PHENOTYPIC ADAPTABILITY OF BUNCH GROUNDNUT (ARACHIS HYPOGAEA L.) FOR POD YIELD DURING SUMMER

Published on

Twenty-nine bunch groundnut genotypes were evaluated for adaptability under summer
condition across four environments for pod yield. Both linear and nonlinear portions of
genotypes X environment (G X E) interaction accounted for the expression for pod yield.
However, the predictable portion was significantlyhigher than the nonpredictable portion.
Most of the genotypes were responsive to the fluctuations in agroclimatic conditions. The
high yielding genotype J (E)-l showed wider adaptability over environments. High
yielding genotypes which exhibited greater response to favourable environments were also
identified. High pod yield coupled with high response results in greater instability, while
medium pod yield with average response leads to stability of the genotypes.
