Variety name: Taimai 601

Applicant: Jiangsu Hongqi Seed Industry Co., Ltd.

Breeder: Jiangsu Hongqi Seed Industry Co., Ltd.

Variety source: Huai 0454/week 98165, the name of the test is "Taimai 601"

Characteristics: Weak spring wheat varieties. The seedlings are semi-creeping and the leaves are green. Strong tillering power and general cold resistance. The plant type is compact, the ear layer is neat, and the lodging resistance is good. Get up earlier at jointing and get better familiarity. Spike fusiform, long awns, white shells, white grains, oblong grains, semi-horny-horny. The average result of the regional test: the whole growth period is 225.3 days, which is 1.3 days shorter than that of the control Huaimai 20. The plant height is 82.0 cm, the effective ears per mu is 413,000, the ears are 34.3, and the thousand-grain weight is 42.5 grams. Approved by the Institute of Plant Protection, Jiangsu Academy of Agricultural Sciences, and the Xuzhou Institute of Agricultural Sciences, Xuhuai Prefecture, Jiangsu: moderately susceptible head blight (inoculation identification of moderately susceptible head blight, severity 2.8, 3.1; natural incidence identification of moderately susceptible head blight, Disease refers to 18.1, 0.0), moderately resistant to yellow mosaic disease, moderately susceptible to stripe rust, highly susceptible to powdery mildew, sheath blight, and leaf rust. Appraised by the Institute of Germplasm Resources and Biotechnology, Jiangsu Academy of Agricultural Sciences: susceptible ears germinate. Measured by the Grain Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture: Bulk weight 816g/L, 800g/L, protein (dry basis) 15.5%, 13.7%, wet gluten 32.6%, 33.4%, water absorption rate 61%, 60%, stable time 6.3 min, 8.7min, the maximum tensile resistance is 276E.U., 415E.U., the tensile area is 64cm2, 80cm2, the hardness index is 58.9, 60.4. The 2018-2019 quality index reaches the certification standard for medium-strength gluten wheat varieties.

Yield performance: Participated in the Huaibei wheat group A regional test in Jiangsu Province from 2017 to 2019. The two-year average yield was 570.7 kg per mu, which was 3.0% higher than the control Huaimai 20. Participated in the production test in 2019-2020, the average yield per mu is 578.2 kg, which is 4.8% higher than the control Huaimai 20.

The key points of cultivation techniques: 1. The suitable sowing period is October 25th to November 5th. 2. The basic seedlings per acre are about 160,000 at the right time. Sowing is delayed or the fertility level is low should be increased appropriately. 3. Generally, about 18 kilograms of pure nitrogen per mu is applied, together with phosphorus and potassium fertilizers. Nitrogen base fertilizer accounts for 60%, jointing booting fertilizer accounts for 40%, and spraying foliar fertilizers after heading and blooming combined with the prevention and control of pests and diseases. The field furrow system is matched, and attention should be paid to flood prevention and drought resistance. 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, suitable for late cropping in Huaibei wheat area of ​​Jiangsu Province.
