Abstract

The experiment was conducted using 14 genotypes of cowpea to study their yield performance,
variability and correlation under dryland conditions during early and late kharif. The results
showed significant differences among the genotypes evaluated for all the characters. The four
genotypes IT-38956-1, KBC-1, KBC-2 and TVX -944-02E have performed better during both the
seasons, thus these genotypes are well fitted in double cropping system. Variability studies indicated
that all the characters were predominantly governed by additive gene action during both the
seasons; however the branches/plant during late kharif was the exception. Correlation studies
revealed that seed yield was correlated positively with all the characters during early kharif, but
during late kharif, it was correlated only with the plant height.
