摘要	Taro, Colocasia esculenta (Araceae), is a widely distributed and important food crop in the humid tropics and subtropics. Relatively neglected by science, much knowledge of genetic diversity in taro is with farmers. Taro genetic resources managed by five ethnic communities and Han farming villages in diverse ecosystems were sampled and characterized in Yunnan Province, southwest China. This study documented a new type of flowering taro selected by farmers which is widely and intensively cultivated for its edible flower. Samples representing 20 traditional cultivars were grouped into five major morphotypes according to ethnobotanical, agro-morphological, and preliminary genetic characterization. Folk taxonomy and uses tended to confirm the five morphotypes recognized by peoples of Yunnan for their distinctive properties and uses. These major taro morphotypes are key units for assessing how patterns of use maintain genetic diversity and to monitor potential genetic erosion. The morphotype groups also suggest possible evolutionary relationships in cultivated taros.
