Variety source Beijing Hybrid @#@245@#@ Engineering Technology Research Center Jingdong No. 6 / CIM Dasui

Approval status Beijing Approved Wheat 2003003

Characteristics Winter type, medium maturity. Seedlings semi-erect, leaves dark green, tillering ability and spike-forming rate medium. Spike spindle-shaped, long awns, white glumes, red grains. Plants vigorous, plant height 80-85 cm. Spike number per mu 428,000, grains per spike 29.3, 1,000-grain weight about 40 g. Good lodging resistance, relatively strong cold resistance. Quality analysis results by this unit are: in 2001, moisture 11.2%, protein content 13.1%, wet gluten content 40.7%, sedimentation value 33.4 ml, dough stability time 4.5 minutes; in 2002, moisture 11.3%, protein content 13.6%, wet gluten content 39.8%, sedimentation value 31.2 ml, dough stability time 3.5 minutes.

Yield performance In the two years 2000-2001 and 2001-2002, it participated in the Beijing winter wheat regional trial, with an average yield per mu of 406.1 kg, 1% higher than the control Jing 411.

Cultivation points 1. The suitable sowing period in the Beijing area is September 25 to October 5, and the suitable basic seedling number is 150,000-250,000 per mu. 2. Scientific fertilization: the base fertilizer is preferably diammonium phosphate 15 kg/mu and urea 15 kg/mu; the green-turning fertilizer can be appropriately supplemented according to seedling conditions and soil fertility; the jointing fertilizer applies urea 10-15 kg/mu. 3. Reasonable irrigation: ensure timely irrigation of "bottom moisture water", "freezing water", "jointing water" and "grain-filling water".

Suitable region Suitable for planting in wheat regions with medium to above-medium fertility levels in the Beijing area.
