Abstract: Upland rice varieties are collected in Daka, Baka and Mannalong villages. Socio- economy situation and upland rice varieties diversity of 39 households in each village were investigated using structure and semi - structure interview based on household based agrobiodiversity assessment. The results are as follows: upland rice resources and their diversity in morphology and genetics were discovered through investigation on upland rice resources in the three villages. Some upland rice varieties of good quality are disappearing and most are fit for poor soil. The number and varieties of upland rice which farmers plant are influ-enced not only by the area of upland rice and swidden but also by fanners' hobbies, planting techniques, market, and culture. So we must take measures to protect upland rice varieties.
