Linfeng No. 3 bred by Institute of Wheat Research, Shanxi Academy of Agricultural Sciences is a winter wheat variety with high - quality, drought resistance and high yield. The results of regional test in Shanxi and Hebei Province showed that Linfeng No. 3 is a variety with high yield, high quality, resistance to drought and diseases. The average yield of Linfeng No. 3 is 3862.5-5460.0 kg/hm^2, 7.58 % -13.04 % higher than that of the control variety. The content of protein, wet gluten, sedimentation value, development time, stability time, steamed bread valuation, noodle valuation are 15.26 %, 32.7 %, 52.2mL, 5.5min, 7.2min, 86.5 and 82.5, respectively. The roots are well-developed,its index of drought resistance is 1.13. The function period of leaves is long and the seeds are plump. The plant height, the grains per spike and the 1000-grain weight is 75 - 80 cm, 35- 40 and 40-45 g, respectively. It is suitable to cultivate in dry lands in southern of Shanxi, Hilonggang of Hebei, and Weinan and Weibei of Shaanxi.
