In the more tropical countries of this region, such as Thailand, the Philippines, and Indonesia, there is increasing interest in domestic wheat production. At this early stage of genotype and management development, wheat cannot be expected to compete with adapted traditional crops. Rather, it should be promoted as an additional crop in rotations in which there is a crop void during the cool, dry season. This can occur for various reasons in rainfed upland or rice paddy situations. In the former, on-farm yields of up to 2.5 t/ha, and in the latter, up to 5 t/ha, have already been recorded. Further yield increases can be expected from improved germplasm and crop management techniques. Input costs are a major factor in the farming communities throughout the region. There is a potential danger that fertility depletion by the additional wheat crop may result in a reduction of yield in the subsistence crop of rice or maize
