Characteristics: weak spring sex, middle early maturity, maturity at the same time as control Yanzhan 4110. Seedlings erect, leaves erect, tillering ability medium. Plant height about 82 cm, plant type is more compact, flag leaves wide short, thick, on the top, ear layer neat, ear more ear uniform, yard density. Spike spindle type, long awn, white hull, white grain, semi-horny grain, medium plumpiness, low black embryo rate. The panicle rate was higher, the average panicle number per mu was 448,000, the grain number per panicle was 29.8, and the 1000-grain weight was 43.1 g. Seedling growth flourishing, winter cold resistance is better. Spring rose quickly, jointing early, not resistant to late spring cold. High temperature resistance, long leaf function period, smooth filling, good maturity. Lodging resistance is medium. Identification of disease resistance: moderate resistance to powdery mildew, moderate susceptibility to stripe rust, leaf rust, high susceptibility to stem rust, scab, sheath blight. Field performance of regional trial: leaf tip is heavier. In 2006 and 2007, mixed samples were measured respectively: bulk density 781 g/L, 776 g/L, protein (dry basis) content 14.2%, 13.92%, wet gluten content 31.5%, 32.1%, sedimentation value 28.8 ml, 31.6 ml, water absorption 59.2%, 60.0%, stable time 2.2 minutes, 2.4 minutes, maximum resistance to elongation 188 E. U, 242 E. U, elongation 18.1 cm, 18.2 cm, Stretching area 50 cm2, 64 cm2.

Yield performance: In 2005~2006, we participated in the regional test of spring water group varieties in the south of Huanghuai winter wheat area, with an average yield of 558.3 kg per mu, 4.13% higher than that of control 1 Yanzhan 4110, and 11.62% higher than that of control 2 Yumai 18-64. In 2006~2007, we continued the test, with an average yield of 532.4 kg per mu, 4.8% higher than that of control Yanzhan 4110. The average yield per mu was 503.2 kg in 2006~2007, 4.5% higher than that of Yanzhan 4110.

Key points of cultivation technology: suitable sowing time is October 15~30, suitable for basic seedlings 140 thousand ~ 180 thousand seedlings per mu, pay attention to lodging prevention in high water and fertilizer land. Pay attention to the control of sheath blight and scab.
