Lingua 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/hm^2, 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/hm^2 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 era, 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.
