Genetic relationships among 24 lines of 9 Vigna species were determined using cluster analyses by UPGMA of 30 morphological characters, covering 5 growth stages. The 5 growth stages were the first two true leaf stage, the fully expanded fourth leaf stage, the flowering stage, the mature stage and the harvest stage. Nineteen lines clustered into 5 groups. The first group comprised 4 lines of V. mungo var. silvestris. The second group comprised two lines each of V. mungo and V. radiate. The third group comprised V. umbellate with accession numbers 17, 18, 51, 54 and 55. The fourth group comprised V. reflexo-pilosa accession number 26, and V. trinervia accession numbers 44, 47 and 74. The fifth group comprised V. umbellate accession number 43 and V. glabrescens accession number V1160. However, using bands of 6 isozyme systems, i.e., EST, PER, MDH, SDH, GOT and 6PGDH, all 24 lines were finally clustered into 4 groups. The first group comprise 4 lines of V. mumgo var. silvestris. The second group contained V. umbellate accession numbers 17, 18, 51 and 54. The third group were two lines each of V. mungo and V. radiate, V. umbellate accession numbers 43 and 55, and V. trinervia accession numbers 47 and 74. The fourth group were 3 lines of V. reflexo-pilosa, and V. trinervia accession numbers 17 and 44, V. glabrescens accession number V1160, V. angularis accession number 40 and V. aconitifolia accession number 83.
