Anthracnose resistant (Bilep and SEA 189) and virus tested (White Lisbon) Dioscorea alata cultivars were introduced into Dominica in 1982-1984. In evaluation at La Plaine Agricultural Station, yields of White Lisbon in 1982 (2.8-4.8 kg/plant) compared favourably with small farms (1.8-2.7 kg/plant). High yields with pen manure suggest further yield improvements by augmenting plant nutrition. Anthracnose was present at increased levels with later generations which may have been induced by the virus-testing process. Anthracnose damage in Bilep did not increase or have an adverse effect on yield
