[Abstract]
Lingxuan 6 is a new winter wheat cultivar, bred by sexual crossing with Q104-3 as female parent and Lantian 16 as male parent, after years of continuous natural elimination and artificial selection. In 2016 — 2018, the average yield of 2 a 14 sites(times) was 4 330.5 kg/hm2, which was 9.4% higher than that of the control cultivar Longyu 4 in Regional Trail in Gansu Longdong. It is a strong winter medium maturing wheat cultivar with the growth period is 275 days. The plant height is 85 cm, the ear length is 7~8 cm, the 1000-grain weight is 46.8 g, the bulk density is 791.5 g/L. The grain contains crude protein(dry basis) is 138.7 g/kg, wet gluten is 257.3 g/kg, crude starch(dry base) is 653.4 g/kg, ash(dry basis) is 17.8%, sedimentation value is 31.2 g/mL, which belongs to strong gluten wheat. It has good comprehensive disease resistance, stripe rust immunity, medium resistance to powdery mildew, strong cold resistance, drought resistance, lodging resistance. It is suitable to be grown in planted in Pingliang, Qingyang and other ecologically similar areas in Longdong winter wheat region.
