Abstract
In the Caribbean several epidemics of yam anthracnose have led to the demise of sustainable production of White Lisbon yam. Research into yam anthracnose at the University ofthe West Indies, Cave Hill Campus has shown that C. gloeosporioides isolates from yam are host-selective isolates ofYam C. gloeosporioides causing yam anthracnose were capable of infecting yarn only, while isolates from other crops such as citrus and mango did not infect yam. RAPD analysis ofthese isolates showed that isolates from yam were genetically similar, but distantly related to isolates from other crop types. Moreover, phytotoxin studies supported the host-selective nature of C. gloeosporioides isolates causing yam anthracnose. This results and information on epidemiology on yam anthracnose were used to develop and test a model for establishing large-scale of White Lisbon yam production in Barbados.
