Tuber crops like yam (Dioscorea sp.), dasheen (Colocasia esculenta) and cocoyam (Xanthomona sp.), grown for food in tropical and subtropical regions of the world, are of socio-economic importance to many producing countries. However, they are produced below demand and are under-exploited. Problem areas include inefficient traditional production methods, poor shelf life and inadequate research of the crops. The University of the West Indies Yam Research Team, in collaboration with researchers in the United Kingdom (Wye College), Germany (Frankfurt University), Nigeria (University of Benin) and the USA (Chicago State University), has addressed yam production problems to varying extents with the following approaches: in vitro techniques for the development of an effective commercially feasible propagation system for production of yam planting materials;biochemical and molecular genetic studies on tuber composition, tuber storage, sprouting and senescence;gene technology for yam genome analysis, genetic variability among cultivars and molecular tagging of traits of agronomic importance; study of Yam Associated Microbes (Y A M) for purposes of biotechnological exploitation and yam protoplasts for transient gene expression and regenerative analyses.....
