Description Fifteen cultivars differing in plant type and maturity were evaluated for their reproductive efficiency and yield at the ICRISAT Sahelian Center, in Niger in 1988, 1989 and 1990. Flowers and pods were used to determine the reproductive efficiency and yield differences were assessed by using crop growth rate and partitioning. Significant differences among cultivars were observed for their ability to flower and set pods under high temperature conditions. The pattern of flowering and pod set showed that flowers formed in the first 10 days after initial flowering had the highest percentage pod set. Potential pod set ranged from 5 to 81%. TN88-63, the most widely adapted cultivar in the Sahel averaged 59% pod set followed by A73-2-1 with 56%. There was considerable variation among cultivars in the duration of the reproductive period, crop growth rate and partitioning. Crop growth rate was largely responsible for differences in yield among cultivars.
