Abstract:

ing at the agricultural damages caused by severe natural disasters, and low and unstable yield in wheat production in the history of Weibei rainfed highland region, we started to breed new wheat varieties from 1964. The wheat varieties have unique advantages in resistance to yellow rust and yellow dwarf diseases, and tolerance to cold, drought and lodging. The varieties also have a high yield potential. The promotion of these varieties has brought variety upgrading in the region for four times, resulting in a dramatic increase of wheat yield from 750-900 kg/hm² in 1960s to 6000-7500 kg/hm² at present. In the study, we summarized wheat breeding experiences for Weibei rainfed highland region based on the breeding practices of the past years, and discussed the prospects for wheat breeding designed for this region.

Key words: Weibe rainfed highland, wheat breeding, resistance, high yield
