The sweet potato, Ipomoea batatas (L.) Lam. (family Convolvulaceae) appears to have originated in tropical South America where there is the greatest diversity of germplasm; secondary centres of diversity are found in Asia and parts of Africa (Purseglove 1968; Austin 1988). It is the seventh most important food crop worldwide (Jansson and Raman 1991) and is grown in 111 countries, particularly in Asia, Africa and South America. According to the Food and Agriculture Organization, annual production in 1984 was 115 million metric tons, and sweet potato ranked third in acreage and second in economic importance of all root and tuber crops (Horton 1988). Sweet potato is an important staple of subsistence farmers, with the vines and roots being eaten or fed to livestock (Yen 1974). It is also used for canning, dehydrating, and flour manufacture, as well as a source of glucose, syrup and starch (Purseglove 1968).
