In India the area production and productivity of blackgram was 4.49mha with 2.93 m tonne … Advertisement. A study was undertaken on the variation in chromosome number of cells from callus tissues originating from cotyledon, hypocotyl and embryonal axis explants of Vigna mungo. V. mungo It belongs to family leguminoseae with chromosome number 2n=2x=22. There has been confusion on the taxonomic status of Vigna mungo and Vigna radiata; because they are closely related it was proposed that they be grouped into a single species. In this investigation the nature and extent of DNA variation between thirteen diploid and one polyploid species have been estimated. Determination of the chromosome numbers of root tip tissue (2n=22) and nodule tissue revealed that nodule tissue contained both diploid and tetraploid cells but no other degrees of polyploidy. Both the varieties were found to possess 2n =22 metacentric chromosomes. Black gram is an economically important Vigna species, which provides high-protein food [3]. - Tropical grain legumes, such as black gram, Vigna mungo, and green gram, Vigna radiata (L.) R.
