The nuclear DNA content and the ploidy levels of 43 accessions of water yam (Dioscorea alata) collected at Save (a district of central Benin) were determined by both conventional chromosome counts (from root tip cells) and flow cytometry. The great majority (42) of the accessions had 40 chromosomes...
