Wheat breeding program in Northern Thailand

Wheat experiments were first conducted in northern Thailand in 1934. Research, particularly breeding, has continued until the present. Most materials, until recently, have been introduced from the CIMMYT and regional National Programs as advanced lines and segregating populations. In 1983, the Rice Research Institute released two bread wheat varieties for northern Thailand, Samoeng 1 and Samoeng 2. In 1987, the Rice Research Institute released two additional bread wheat varieties, Fang 60 and Phrae 60. Wheat yields in farmers' fields are low, about 0.6-0.7 t/ha, although the yields on experimental stations are higher. We have recognized that there are two distinct environments under which farmers may grow wheat in northern Thailand-rainfed upland and irrigated lowland. With this in mind, we have changed our breeding objectives from broad adaptation to specific adaptation towards these two differing environments
