Huaimai 22

Characteristics: semi-winter, mid-late ripening, maturity one day later than the control Yumai 49. The seedlings are creeping, the leaves are small and dark green, the tillering ability is strong, and the panicle rate is medium. The plant height is about 85 cm, the plant type is slightly loose, the flag leaf is narrow and short, overthrust, waxy, elegant appearance, irregular ear layer, dense ear code, good fruiting. Ear spindle ear, long awn, white shell, white grain, grain half-horny, medium plumpness, low black embryo rate, good appearance. The average number of panicles per mu is 403000 ears, the number of grains per spike is 33.0g, and the weight of 1000 grains is 39.7g. It has strong cold resistance in winter, gets up late in spring, develops slowly, heads late, and has better resistance to spring cold. It is easy to age early, but the mature phase is ordinary. The stem has better elasticity and resistance to lodging. Identification of disease resistance: high resistance to stem rust, middle susceptibility to powdery mildew, sheath blight, high susceptibility to stripe rust, leaf rust, scab. The field performance of the regional trial was highly susceptible to leaf blight. In 2005 and 2006, the mixed samples were determined: bulk weight 793g / L, 788g / L, protein (dry base) 13.28%, 13.71%, wet gluten 26.1%, 27.1%, sedimentation value 28.1ml, 28.6ml, water absorption 52.2%, 54.2%, stability time 6.6min, 5.5min, maximum extension resistance 305E.U, 271E.U, extensibility 13.2 cm (2006). The stretched area is 54.0 square centimeters and 52.0 square centimeters.

Yield performance: participated in the variety regional trial of Dongshui group in the south of Huang-Huai winter wheat region from 2004 to 2005, the average yield per mu was 505.8 kg, which was 4.24% higher than that of Yumai 49, which was 4.24% higher than that of Yumai 49, and the average yield per mu was 552.8 kg. The yield was 6.22% higher than that of control 1 Xinmai 18 and 6.76% higher than that of control 2 Yumai 49. In the production test from 2006 to 2007, the average yield per mu was 541.6 kg, which was 9.0% higher than that of Xinmai 18.

The key points of cultivation techniques are as follows: the suitable sowing date is the first and middle of October, and the suitable basic seedlings are 100000 ~ 140000 seedlings per mu. Pay attention to the control of stripe rust, leaf rust and scab.
