Vigna grandiflora showed a much higher number of alleles, allelic richness, observed heterozygosity, gene diversity, and out crossing rate than V. exilis, but a lower fixation index. The average number of alleles was about two times higher than V. exilis.
It also
showed higher allelic richness, which varied from 51.90 to 95.56 with an average of 74.80. Observed heterozygosity was nine times more than in V. exilis. Gene diversity was between 0.43 and 0.77, with a mean of 0.66. Fixation index was moderate to relatively high, with a mean of 0.71. This species showed a much higher outcrossing rate (17.41%) than V. exilis (3.24%).
