Abstract excerpt

The fundamental question about Dioscorea trifida (Dioscoreaceae), the most important Amerindian yam, that remains unresolved concerns its evolutionary origin, since no wild relative has been reported. In this paper we report the existence of D. trifida's wild relative for the first time. The diploidy of wild D. trifida (2n = 40) is clearly demonstrated by flow cytometry, chromosome counts, and microsatellite...
