Abstract

Vigna vexillata chromosome characterization was carried out using the Leishman C-banding technique. The results showed that the chromosomes mostly exhibited bands at both the centromeric and telomeric regions. These bands will serve, as a valuable marker for the identification of the chromosomes. Chromosomes 2 was the most variable and differed from the other chromosomes by the presence of satellite on the short arm. Diploid chromosome numbers of 22 consisting of 11 pairs of homologues were observed for V. vexillata. The homologues chromosomes were arranged in the descending order. The idiogram representing the chromosomes was also constructed.

Key words: LeishmanC-banding, Vigna vexillata and Chromosomes.
