Abstract


Available variability in cowpea is meager due to its breeding behavior. However, variability is the prerequisite for improvement of yield levels in cowpea. In the present study, hybridization was followed to generate variability. Most divergent parents were involved in the crossing programme. Yield attributing traits exhibited higher magnitude of variability parameters in the cross C-152 x Goa loal than KM-1 x Goa local. It is also noteworthy hurt magnitude of PCV and GCV values were maintained in later generations (F3) in case of C-152 x Goa local also on it is always desirable for selection to the more effective. Thus, it was found that semideterminate and indeterminate combination is more potential than determinate x indeterminate demonstrating former combination is a more potential.
