Abstract

The evolutionary relationships between cultivated and wild
species of Asiatic Vigna species were investigated through
biochemical parameters utilizing isozyme variation patterns of
peroxidase, catalase and seed protein polymorphism studied
through polyacrylamide gel electrophoresis. The results of above
investigations are presented in this paper. The studies provide
strong evidence in elucidation of phylogenetic relationships. The
results indicated that mung and urid beans are two distinct
species and they have independently evolved from wild progenitors
V. radiata var. sublobata and V. mungo var. silvestris,
respectively, which show remarkable similarities in isozyme
profiles particularly in number of bands, position and Rf values.
The wild putative forms occurring in natural habitats belonging
to V. umbellata, V. aconitifolia and V. trilobata also appear
to be quite distinct. They exhibited fewer bands. Close affinity
could not be discovered as revealed by protein and isozyme
polymorphism.
