The response of yam (Dioscorea) cultivars to artificial and natural infections with minisett rot pathogens was investigated. None of the 20 yam cultivars were resistant to Sclerotium rolfsii [Corticium rolfsii] or Trichoderma longibrachyatum. Cultivars TDa 84/093, 85/236, 85/257, TDr 608, 745, 81...
