[Abstract]
Jingning 13 is a new winter wheat cultivar(the original code name was Jing 2011-7) was bred with Jingning 10 as the female parent and V8448 as the male parent through sexual hybridization and multi-generation group mixed selection. In 2015 — 2017, the average yield in 2 a 12 sites(times) was 4 426.5 kg/hm2, which was 8.2% higher than that of the control cultivar Longzhong 1. In 2015 — 2016, the average yield was 3 937.5 kg/hm2, which was 5.3% higher than that of the contral cultivar. In 2016 — 2017, the average yield was 4 915.5 kg/hm2, which was 11.0% higher than that of the control cultivar. In 2017 — 2018, the average yield was 4 341.0 kg/hm2, which was 4.3% higher than that of the control cultivar. The plant height is 61~102 cm, ear length is 5.4~7.1 cm, seed setting spikelets are 15~18, grains per ear are 32.2, 1000 grain weight is 41.5~45.2 g, volume weight is 786 g/L. The crude protein content is 12.7%, lysine content is 0.33%, wet gluten content is 24.8%, sedimentation value is 32(ML, 14% water basis), total ash content(dry basis) is 1.4%, water content is 8.42%. It is moderate susceptibility to stripe rust and powdery mildew. It has drought resistance of grade 2, cold resistance of grade 2, and green dry resistance of late stage. It is suitable to be grown in arid and semi-arid areas with annual precipitation of 300~500 mm and altitude below 2 200 m in Pingliang, Dingxi and Guyuan of Gansu Province.
