Verification Announcement and Supply Information of Strong Gluten, Cold Resistance, Lodging Resistance and Disease Resistance Wheat Variety Zhengmai 366
Authorized Number: National Authorized Mai 2005003
Variety Name: Zhengmai 366
Breeding Unit: Institute of Wheat, Henan Academy of Agricultural Sciences
Source: Yumai 47/PH82-2-2
Characteristic: Half-winter, Early-Middle maturity, maturity 1-2 days earlier than Yumai 49. Seedlings semi-creeping, yellow-green leaves. The plant height is about 70 cm, the plant type is compact, the panicle layer is neat, the panicle is yellow-green, and the flag leaf is rushing upward. Spike spindle type, long awn, white shell, white grain, keratinous grain, fuller, medium black embryo rate. The average number of ears per mu is 396,000, the number of grains per ear is 37, and the weight of 1000 grains is 37.4 grams. Overwintering cold resistance is good, the ability to resist cold in late spring is weak, the ability to resist lodging is strong, not tolerant to hot and dry wind, and late maturity is general. Identification of inoculation resistance: high resistance to stripe rust and stem rust, moderate resistance to powdery mildew, moderate susceptibility to scab, high susceptibility to leaf rust and sheath blight. Natural identification in the field, highly susceptible to leaf blight. In 2004 and 2005, the mixed samples were determined: 795 g/l, 794 g/l, 15.09%, 15.29% of protein (dry base), 32% of wet gluten, 33.2% of wet gluten, 42.4 ml of sedimentation value, 47.4 ml of water absorption, 63.1% of water absorption, 6.4 minutes, 9.2 minutes of dough formation, 7.1 minutes, 13.9 minutes of stability, 462 E.U., 470 E.U., 110 square centimeters of stretching area. Mi, 104 square centimeters. It belongs to strong gluten variety.
Yield performance: Participated in the regional experiment of Dongshui group in the southern part of Huanghuai winter wheat area in 2003-2004, the average yield per mu was 544.9 kg, 0.7% higher than that of Yumai 49, a high-yielding control, and 7.2% higher than that of high-quality control, Gao 8901 (extremely significant); the average yield per mu was 482.9 kg in 2004-2005, 0.3% lower than that of Yumai 49, a high-yielding control, and 6.3% higher than that of high-quality control. 5% (very significant). In 2004-2005, the average yield per mu was 460 kg, which was 0.3% higher than that of Yumai 49.
Key points of cultivation techniques: suitable sowing date is October 10-25, suitable for 120,000-160,000 seedlings per mu, pay attention to control leaf blight, sheath blight and scab.
Approval Opinion: This variety meets the national wheat variety approval standard and passes the examination and approval. It is suitable for early and middle stubble cultivation in middle and Northern Henan Province, northern Anhui Province, Guanzhong District of Shaanxi Province and Heze Middle and High Yield Water and Fertilizer Land of Shandong Province in the southern part of Huanghuai Winter Wheat Region.
