The Yam ( Dioscorea alata L.) as one of the varieties of the “uwi” plant has the potential to support food diversity and food security in the future. This plant is very tolerant to be planted on dry land which in Indonesia is abundant even in the world. The purpose of this study was to obtain alternative types of non-rice food from Uwi, starting with the identification of the variation and multilocation yield test to see the adaptation of each accession were obtained at various upland agro-system, Cluster analysis on plant diversity based on tuber morphological properties obtained 13 groups with 80% similarity level. While the results of adaptation tests indicate that Yam generally can adapt to various agro-ecological, but only a few accession can grow well under teak stands, especially those with large trunks and tubers. The best yield is in the upland of highlands of the Ponorogo region, followed by the lowlands of Madiun and the lowest under teak stands. However, certain types can adapt to a broad spectrum of agroecology.
