Wanmai 52

Characteristics: semi-winter, middle and late ripening, and the mature stage was 1-2 days later than that of Yumai 49 and Xinmai 18. The seedlings are semi-creeping, the leaves are slender, upward thrust, the tillering ability is medium, and the panicle rate is high. The plant height is about 85 cm, the plant type is compact, and the flag leaf width is short and upthrust. The ear layer is thick, the ear spindle type, the ear is uniform, the ear head is small, long awn, white shell, white grain, grain semi-horny, good gloss, good plumpness, medium black embryo rate and good commercial quality. The average number of ears per mu is 400000 ears, the number of grains per ear is 36.3grains, and the weight of 1000 grains is 40.9g. The seedling growth is strong and the cold resistance is good. Get up earlier, polarize quickly, and heading later. It is sensitive to low temperature in spring. With a certain degree of drought tolerance, ripe phase is good. The elasticity of the stem is general, and the lodging resistance is medium. Identification of disease resistance: moderately resistant to slow leaf rust, moderately susceptible to stem rust, powdery mildew, stripe rust, highly susceptible scab, sheath blight. The field performance of regional trial was moderately susceptible to leaf rust. In 2006 and 2007, the mixed samples were determined: bulk weight 796g / L, 798g / L, protein (dry base) 13.41%, 14.85%, wet gluten 31.2%, 32.3%, sedimentation value 29.3ml, 26.2ml, water absorption 66.7%, 51.2%, stability time 2.6min, 2min, maximum extension resistance 120E.U, 193E.U, extensibility 14.5cm, 15.4cm. The stretched area is 26 square centimeters and 43 square centimeters.

Yield performance: participated in the regional trial of Dongshui group varieties in the southern part of Huang-Huai winter wheat region from 2005 to 2006. the average yield per mu was 559.9 kg, which was 6.29% higher than that of control 1 Xinmai 18 and 6.82% higher than that of control 2 Yumai 49. The average yield per mu was 554.7 kg, which was 6.29% higher than that of control Xinmai 18. In the production test from 2006 to 2007, the average yield per mu was 526.1 kg, which was 6.3% 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 preventing lodging in high water and fertile land. Pay attention to the control of scab and sheath blight.
