Summary

Field assessments of varietal contamination from entomophilous outcrossing in okra revealed that the plant characters employed in such assessments influenced the estimate of contamination expressed as percentage of offtypes. In Nigeria, complex cropping systems, land use patterns and the abundance of insects associated with okra flowers make the effective isolation of seed crops difficult. Also, the largely subsistence production where annual seed purchase is infrequent, and consumers' acceptance of variable and ungraded edible okra fruits, imply that breeding for uniform or pure varieties may not be appropriate. Consequently, a composite bulk variety is proposed for growing or seed multiplication in areas where edible fruit production is envisaged. In this way, the difficulty of pure seed production or unwanted adulteration of varieties will not pose problems to breeders or farmers.
