[Abstract]
Lingtai 4 is a newly bred winter wheat variety by parental combination of lantian 10 with 95-3-5 after many years of continuous selection. The average yield of two years of Lingtai 4 the variety reaches 4 846.95 kg/hm2, which is 7.37% higher than that of the check Xifeng 27 in the regional test conducted in the period 2011 — 2013, the production is the sixth. The yield of production reached 8 422.50 kg/hm2 in the period 2011 — 2012 in Demonstration area of Lintao county . The result shows that plant height, panicle length, 1 000-grain weight, bulk density, growth period are 85 cm, 6.6 cm, 42.5 g, 762.9 g/L, 285 d, respectively, it is the middle maturing varieties. The result also indicates that seed crude protein(dry basis), wet gluten, sedimentation value, crude starch(dry basis), ash (dry basis) are 135.0 g/kg, 209.2%, 19.7 mL, 656.3 g/kg, 16.1%, respectively. In addition, Lingtai 4 is assume good resistant to diseases, immune to stripe rust, light susceptible to powdery mildew, good resistance to rust, and resistance cold, resistance drought, resistance lodging . It is suitable to be grown in the winter wheat area of arid mountain plateau of Pingliang, Qingyang of Gansu, and other similar areas .
