The nutrient-rich tubers of the greater yam, Dioscorea alata L., provide food and income security for millions of people around the world. Despite its global importance, however, greater yam remains an orphan crop.

- * Developing genetically resistant varieties could provide a sustainable solution to this disease, but progress has been slowed due to the crop's biological traits and common propagation methods.
- * Researchers have created a detailed genetic linkage map using 380 polymorphic EST-SSRs and identified a key QTL on linkage group 14 that consistently shows resistance to anthracnose over multiple years of testing.
Anthracnose, caused by Colletotrichum gloeosporioides, is one of the major constraints limiting water yam (Dioscorea alata) production in the tropics. In this region, yam anthracnose control is mostly achieved by the deployment of moderately resistant yam genotypes. Therefore, screening for new sources of anthracnose resistance is an important aspect of yam research in the tropics.
