Abstract: Rice cultivation there is characterized by lower yields and greater instability than in the rest of Thailand.Rain-fed rice cultivation in Don Daeng village of Northeast Thailand was studied by the author and his colleagues in 1981 and 1983.They reported that the general situation had shown no remarkable changes since the 1960s, when K Mizuno carried out an anthropological survey in the area [Mizuno 1981], although some farmers had begun to use power tillers or chemical fertilizers.A further survey was carried out frorn June 1991 to June 1992.The major change recognized was acreage expansion of the modern improved glutinous rice variety RD6, which was released in 1977 for the Northern and Northeastern regions by the Rice Division of Thailand.Peasant farmers prefer planting glutinous rice to the non-glutinous type there In the Northeast, especially in northern part of the Mun River basin, glutinous rice is the main staple food, For example, approximately 90% of the paddy fields in Don Daeng were planted to many glutinous rice varieties in 1981 and 1983.RD6 was improved from Khao Dawle Mali 105 (KDMLI05) by active radiation breed- ing.It is photosensitive, as is KDMLI05, but taller [Bunduang and Uchin 1990: 13-14].
