Breeding Report of A New Winter Wheat Cultivar Pingliang 43

Pingliang 43 was a new winter wheat cultivar bred by crossing with the parental combination of ＂1ong-131＂/ ＂82 （51） -9-5-3-2＂. The average yield of Pingliang 43 was 5 540. 85 kg/hm^2 and 7.29% higher than the check Longyuan 936 in winter wheat regional test which was conducted during the period 2000--2003. The result showed that Pingliang 43 was moderate infection to mixture bacteria at the seedling stage, while this cultivar was immune to moderate infection to CY 29, Luo 13 11 , CY 32 at the adult stage. The result also indicated that seed crude protein, lysine, wet gluten and sedimentation value were respectively 15.76%, 0. 47%, 29.3% and 55 mL, and the average thousand grain and bulk weight were respectively 36.01 g and 781.0 g/L, except that it was good with resistance to freeze and drought. Pingliang 43 was suitable for planting in arid areas with rich soil, irrigated areas, open or covered planted areas of eastern Gansu.
