Huaimai 25

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 dark green, the leaves are narrow and straight, the tillering ability is strong, and the panicle rate is medium. The plant height is about 87 cm, the plant type is compact, the flag leaf is rolled out, the ear layer is thick, the spike is even, the fruit is good, the stem is waxy, and the appearance is elegant. Ear spindle type, long awn, white shell, white grain, grain half-horny, good plumpness, low black embryo rate and good appearance. The average number of ears per mu is 416000 ears, the number of grains per spike is 37.4 grains, and the weight of 1000 grains is 38.3g. The seedling growth is general, and the cold resistance is good. It is late to get up in spring and polarize quickly. The heading stage is late, the growth is better in the middle and later stage, and the functional period of the leaves in the later stage is long, with a certain degree of drought tolerance, high temperature tolerance in the later stage, fast filling speed and good ripening phase. The elasticity of the stem is general, and the ability of lodging resistance is weak. Identification of disease resistance: resistance to stem rust, moderate resistance to sheath blight, slow leaf rust, moderately susceptible powdery mildew, highly susceptible stripe rust, scab. The field performance of the regional trial was moderately susceptible to leaf blight. In 2006 and 2007, the mixed samples were determined: bulk weight 801g / L, 796g / L, protein (dry base) 13.04%, 13.75%, wet gluten 25.2%, 27.8%, sedimentation value 26.7ml, 26ml, water absorption 53.2%, 54.2%, stability time 7.8min, 6.6min, maximum extension resistance 382E.U, 360E.U, extensibility 11.0cm, 11.2cm. The stretched area is 58 square centimeters and 56 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 563.3 kg, which was 6.95% higher than that of control 1 Xinmai 18 and 7.49% higher than that of control 2 Yumai 49 in 2006-2007. the average yield per mu was 565.1 kg, 8.27% higher than that of Xinmai 18. In the production test from 2006 to 2007, the average yield per mu was 530.3 kg, which was 7.2% higher than that of Xinmai 18.

Key points of cultivation techniques: the suitable sowing date is in the first and middle of October, and the suitable basic seedlings are 100000 ~ 140000 seedlings per mu, and attention should be paid to prevent lodging under high-yield cultivation conditions. Pay attention to the control of stripe rust, leaf rust and scab.
