Abstract: The genus Phaseolus belongs to the tribe Phaseoleae of the family Papilionaceae (Hooker 1875, Willis 1931).This is an important genus, several species of which are grown in India and abroad due to its profound economic value.However, little work has been done as regards to the cytology and genetics of this genus (Sen, N. K. and Ghosh, A. K. 1960, Datta and Sen 1963, Krishnan and De 1965, De and Krishnan 1967, Singh and Roy 1970, Sinha and Roy 1970).Dana (1966 a, b, c) has studied the inter-relationship of the yellow flowered species of Phaseolus through hybridization and has ascertained the role of inversion and translocation in the speciation within this genus.Yarnell (1965) has also studied the cytogenetics of a few species of Phaseolus.Most of the species of Phaseolus are diploid with 2n=22 and it appears that there is a perfect uniformity in chromosome number of this genus.The wide morphological divergence in respect of the colour of flowers, size of the seeds, pod size etc. amongst the species of this genus can, therefore, be assumed to have been
