Seedlings semi-erect, strong tillering ability, light green leaf color, yellowing of basal seedling leaves in winter, vigorous growth. Plant height about 80 cm, plants relatively compact and uniform, mature plant leaves medium length and width, slanting upward. Spike layer moderately uniform, good seed set. Spike rectangular, long awns, white glumes, light red grains, grain texture corneous to semi-corneous, uniform and plump. Average spike number per mu 255,000 spikes, grains per spike 35.9, 1000-grain weight 43.9 g. Disease resistance identification: immune to powdery mildew, highly resistant to stripe rust, slow leaf rust, highly susceptible to fusarium head blight. Mixed samples tested in 2005 and 2006 respectively: test weight 750 g/L, 755 g/L, protein (dry basis) content 12.10%, 13.48%, wet gluten content 21.9%, 22.5%, sedimentation value 16.8 ml, 19.1 ml, water absorption 53.3%, 56.8%, stability time 2.1 minutes, 1.7 minutes, maximum resistance to extension 115 E.U, 105 E.U, extensibility 14.8 cm, 13.8 cm, extension area 22.9 sq cm, 19.7 sq cm.

Yield performance: In the 2004-2005 season, participated in the regional trial of winter wheat varieties in the upper reaches of the Yangtze River, average yield per mu 371.6 kg, an increase of 6.2% over the control Chuanmai 107; in the 2005-2006 season continued trial, average yield per mu 381.5 kg, an increase of 3.4% over the control Chuanmai 107. In the 2006-2007 season production trial, average yield per mu 384.7 kg, an increase of 8.52% over the local control variety.

Key cultivation techniques: Sow around the start of winter, suitable basic seedlings per mu 120,000-160,000 seedlings, cultivate under relatively high fertilizer and water conditions. Pay attention to the prevention and control of fusarium head blight.
