Variety source: Zhenmai 9/7408, test name "Ninghong 1479"

Characteristics: Spring wheat varieties. The seedlings stand upright with medium tillering power. The plant type is more compact,

Lodging resistance is average. The ear layer is neat and mature. Spike fusiform, long awns, white husk, red kernels, semi-horny kernels. The average result of the regional test: the whole growth period is 209.4 days, which is equivalent to the control Yangmai 20. The plant height is 87.2 cm, the effective ear per mu is 334,000, the per ear is 36.9, and the thousand-grain weight is 43.3 grams. Approved by the Institute of Plant Protection of Jiangsu Academy of Agricultural Sciences and the Xuzhou Institute of Agricultural Sciences in Xuhuai Prefecture, Jiangsu Province: medium resistance to scab (resistance to scab in inoculation identification, severity 1.1, 2.5; resistance to scab in natural disease identification, Disease refers to 1.3, 0.0), medium resistance to stripe rust, yellow mosaic virus disease, high susceptibility to sheath blight, powdery mildew and leaf rust. Appraised by the Institute of Germplasm Resources and Biotechnology, Jiangsu Academy of Agricultural Sciences: high resistance to spike sprouting. Measured by the Grain Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture: bulk density 808g/L, 828g/L, crude protein (dry basis) 14.3%, 14.9%, wet gluten 31.0%, 35.1%, water absorption rate 61%, 64%, stable time 2.0min, 6.6min, maximum tensile resistance 290E.U., 401E.U., tensile area 77cm2, 80cm2, hardness index 62.9, 63.5.

Yield performance: 2017-2019 participated in the regional test of Huainan wheat group A in Jiangsu Province, and the two-year average

The average yield per mu is 502.8 kg, which is 4.5% higher than the control Yangmai 20. Participating in the production test in 2019-2020, the average yield per mu is 506.4 kg, which is 3.4% higher than the control Yangmai 20.

The key points of cultivation techniques: 1. The suitable sowing period is from late October to early November. 2. Sowing every

The basic seedlings per mu are about 150,000, and the late sowing should be increased appropriately. 3. Generally, 16 kg of pure nitrogen per mu is applied, of which basal seedling fertilizer accounts for 60%, jointing booting fertilizer accounts for 40%, and phosphorus and potassium fertilizers are used in combination, and foliar fertilizers are properly sprayed in the later period. The field ditches are matched to prevent bright waterlogging and dark waterlogging. 4. Timely control field weeds before winter and early spring. Pay attention to the prevention and control of pests such as sheath blight, head blight, powdery mildew, rust and aphids.

Approval opinion: Approved and suitable for planting in Huainan wheat area in Jiangsu Province
