Characteristics: spring, medium maturity, the whole growth period is about 185 days. The seedlings are semi-erect, with strong tillering ability, narrow leaves and vigorous growth. The height of the plant is about 92 cm, and the plant opens slightly. The ear layer is neat and the fruit is good. Panicle oblong, long awn, white shell, red grain, grain half-horny, uniform and full. The average number of ears per mu is 247000 ears, the number of grains per ear is 46.0g, and the weight of 1000 grains is 42.0g. The resistance to toppling is weak. Identification of disease resistance: immune to stripe rust, susceptible to scab, stem rust, highly susceptible to leaf rust and powdery mildew. In 2006 and 2007, the mixed samples were determined as follows: bulk weight 782g / L and 782g / L, protein (dry base) content 12.54% and 12.59%, wet gluten content 24.1% and 25.1%, sedimentation value 22.3ml and 26.0ml, water absorption 54.4% and 55.0%, stability time 2.8min and 2.6min, maximum extension resistance 283E.U, 275E.U, extensibility 15.9cm, 16.2cm The stretched area is 63.1 square centimeters and 62.8 square centimeters.

Yield performance: participated in the regional trial of winter wheat varieties in the upper reaches of the Yangtze River from 2005 to 2006. the average yield per mu was 423.4 kg, 14.7% higher than that of the control Chuanmai 107. In 2006-2007, the average yield per mu was 416.6 kg, which was 10.6% higher than that of the control Chuanmai 107. In the production experiment from 2006 to 2007, the average yield per mu was 409.7 kg, which was 15.12% higher than that of the local control varieties.

Key points of cultivation techniques: the Beginning of Winter sowed before and after sowing, suitable for basic seedlings of 100000 ~ 140000 seedlings per mu, cultivated under the condition of high fertilizer and water. Watch out for lodging.
