บทคัดย่อ (EN): The trial on Participatory Variety Selection (PVS) was conducted on 9 sites in wet season 2004.Twenty-two traditional varieties, with diverse agronomic characteristics were used to grow in farmers’ fields. The trials conducted in the first year allow us to redefine growing conditions of target rice growing areas and could be used to select the suitable location to evaluate traditional glutinous varieties (TVs). Sites selected for conducting the trials covered a wide range of main rice planting areas in all three regions: northern, central and southern regions with 3 sites in each region. Participatory variety selection (PVS) approach, in which trials were conducted, is useful in allowing researchers to interact and closely work with farmers and helps breeders understand better about variability of the growing conditions in target areas and responses of cultivars under both inside and outside their origin. It was clear that diverse locations with different topography had effects during the growing season across sites. Higher elevation and lower temperature caused delay in harvesting time in the north. However, the relationships between agronomic characteristics: grain yield, maturity, plant height under trial and preference index of gender was low correlated for all regions. Performance of TVs in response to locations influenced farmers’ acceptance or rejection of those varieties. It was apparent that high yield was a preference character voted by farmers in most sites. Both men and women were more preferred Ikhao, Homdo, Leuathet and Makhing because high yield, large grain and early to medium maturity. Ikhao, Makhing and Homdo varieties were preferred in each region and Yuando was preferred across regions. Some varieties showed specific adaptation to specific regions such as: Yuando is well adapted to the north, TDK4 has good adaptation to central area while Leuathet, Takhiet and Ikhao are well adapted to the south. Cultivars that produced many tillers, big panicles, more grains per panicle, compact panicle and large grain were considered as the farmers’preference for rainfed lowland rice characters. However, preferred agronomic characters that could be defined, as “farmer ideal types” need to be investigated further.
