[Abstract]
Longchun 34 is a newly bred spring wheat variety by crossing the water-saving special, the female parent Mexico imported materials CORYDOL(ink-number 78) with the male parent sexual hybridization Yong 1 023 in Hexi irrigation area. In 2012 — 2013, the average yield of Longchun 34 is 7 513.95 kg/hm2, which is 7.03% higher than that of the check Ningchun 4 in 12 points two-year in Xipian irrigated spring wheat variety area test of Gansu province. In 2014, the average yield of Longchun 34 is 8 006.40 kg/hm2, which is 5.76% higher than that of the check Ningchun 4 the production test, ranking the parameters tested varieties(lines) of the four. Spike type spindle, red grain cutin, the plant height is 78 ~ 98 cm, growth period is 104 days. The average grain number per spike is 35.9, 1 000 grain weight is 48.5 g. Grain containing crude protein is 106.9 g/kg, wet gluten is 22.6%, stable time is 4 min. In the seedling stage, the mixed bacteria shows moderate resistance to the Gui 22-9, Gui 22-14, and resistance to the mixed bacteria, and the CY32, CY33, Shui4 and Shui5 are immune. Compared with the control variety Ningchun 4, the average yield of Longchun 34 is saving water 40% ~ 50%(above 1 800 m3/hm2), WUE increased is more than 0.3 kg/m3. It is suitable for planting in irrigation areas in the west of Gansu province and the northwest of China.
