Susceptibility of yam cultivars to minisett rot pathogens

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, 81/45...

Summary: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, 81/453 and Efuru were not susceptible to Aspergillus niger. Cultivar TDa 382 was not susceptible to Penicillium oxalicum and TDa 84/093, 176, 382 and TDr 608 and 81/453 were mildly susceptible to Botryodiplodia theobromae.
