Karyotypic studies on species of Phaseolus (Fabaceae: Phaseolinae).

Abstract

Ten karyotypes of Phaseolus were analyzed. Possible directions of karyological evolution of those species are suggested. All species studied have karyotypes composed exclusively of metacentric and submetacentric chromosomes, except P. filiformis with all metacentrics, and P. chiapasanus with one pair of subtelocentric chromosomes. Secondary constrictions and satellites are common among species studied. Phaseolus leptostachyus, P. micranthus, and P. macvaughii are considered as aneuploids with 2n= 20, whereas the rest of the species have 2n= 22.
