Abstract
Reproductive efficiency was studied in 10 cultivars of cowpea, evaluated for 2 years. There were significant differences between the cultivars for total number of flowers produced, flower retention, pod drop and yield. Cultivar ‘TVX 3236’, which produced the highest number of flowers, was one of the cultivars that retained the highest number of flowers and its yield was not significantly different from the highest yielding cultivar. Positive correlations were found between total number of flowers produced and total number of pods harvested, and between percentage flower retention and number of pods harvested. Total number of flowers produced, percentage flower retention, number of pods produced and total number of pods harvested were positively correlated with yield. The implications of these findings in improving flower retention in otherwise outstanding cultivars and possible genetic causes of flower/pod abscission in cowpea are discussed.
