Abstract
Cytogenetical studies in Vigna glaberscens TTK1 revealed twenty two and fourty four as haploid and diploid chromosome numbers respectively. Spontaneous occurrence of cytomixis is due to the transfer of chromatin material from one pollen mother cell to other through connecting channel has been noted. Pollen mother cells with reduced chromosome number (n=6, n=7) higher than the modal number (n=22) have also been recorded. Grouping of bivalents and late separating chromosomes were some of the noted abnormalities.
