[Abstract]
Longchun 35 is a newly bred spring wheat cultivar by parental combination of 9064 with Longchun 8139. The average yield of Longchun 35 reaches 3 423.15 kg/hm2, which is 12.06% higher than that of the check Xihan 2 in spring wheat regional test conducted in the period 2014 — 2015 of Gansu province. In 2016, the average yield of Longchun 35 is 3 964.35 kg/hm2, which is 8.93% higher than that of the check Xihan 2 in the production test. The result shows that spike type spindle, red grain cutin, the height is 98 cm, growth period is 98 days. The average grain number per spike is 31.35, thousand kernet weight is 47.9 g, bulk density is 753.0 g/L. The result also indicates that the content of crude protein(dry basis), wet gluten and sedimentation value are 156.0 g/kg, 340 g/kg and 29.8 mL. Longchun 35 is resistance to stripe rust, drought and barren resistant, good yellow fall. It is suitable to be grown in the arid and semiarid area in central Gansu province, such as Dingxi, Baiying, Lanzhou, Gulang and the same ecological environment.
