Abstract
Yam (Dioscorea sp.) is an important staple food crop for many tropical and subtropical countries and foreign exchange earner for Jamaica. Jamaica is the leading producer of yams in the Caribbean with over fifteen local varieties belonging to five cultivated species - Dioscorea alata, Dioscorea cayenensis, Dioscorea rotundata, Dioscorea trifida, and Dioscorea esculenta. Export earnings from yam has gradually increased in Jamaica in the past years. Production is still below demand. Problems associated with production and storage coupled with inadequate research to enhance productive efficiency have caused inconsistent supplies and limitation to international commercialization. Traditional yam cultivation methods are characterized by overdependence on the edible tuber for propogation (up to 40% of harvest is usually reserved for next planting), short shelf life, high storage losses due to infection, infestation and sprouting of the tubers.....
