Summary

Four bruchid-resistant and four susceptible cow-pea cultivars and their F2 crosses were evaluated for oviposition, egg hatching and emergence scores of cow-pea weevils, Callosobruchus maculatus Fabr.

Whereas oviposition and number of eggs hatched were normally distributed, percentage of eggs hatched was not. For percentage weevil emergence, the F2 progenies with susceptible parents as females had a different distribution from that of their reciprocals with resistant parents as females.

Preferential oviposition was not observed among the parents and their F2 progenies. Resistance was observed at the egg hatching and weevil emergence stages. Percentage of eggs hatched was significantly and positively associated with percentage weevil emergence.
