Dioscorea alata L. is a highly important crop, widely distributed in the humid and semi-humid tropics. Flow cytometry was used to determine the ploidy levels of 74 D. alata genotypes collected mainly from West African countries. Sixty three of the genotypes were found to be tetraploid, one was he...

Nuclear DNA content of 54 accessions of 6 Dioscorea species collected from West African countries were determined using flow cytometry. Observed ploidy levels are diploid (2x), triploid (3x), tetraploid (4x), hexaploid (6x) and octoploid (8x). DNA index varied from 0.36 to 1.54 depending on the c...
