What are the wheat varieties with high resistance to scab?

1, Xinong 5 1 1: Identification of disease resistance, high susceptibility to powdery mildew and scab, moderate susceptibility to leaf rust and sheath blight, and moderate resistance to stripe rust. The quality test showed that the grain bulk density was 8 15g/L and 820g/L, the protein content was 14.00% and 14.68%, the wet gluten content was 28.2% and 32.2%, and the stabilization time was1/kloc-. Semi-winter, the whole growth period is 233 days, which is later than the control variety Zhoumai 1 day.

2. Zheng Mai 9023: identified by the Institute of Plant Protection of Henan Academy of Agricultural Sciences and the Institute of Plant Protection of Shaanxi Academy of Agricultural Sciences, it is highly resistant to scab, spindle mosaic virus disease and moderately resistant to leaf blight, leaf rust, stripe rust and sheath blight. Filling is fast, sowing is early, about 3 days earlier than Yumai 18, ear layer is neat, and late maturity is good.

3. Ruihuamai 520: Identification of disease resistance, high resistance to stripe rust, high susceptibility to leaf rust, powdery mildew, scab and sheath blight; The whole growth period of the semi-winter mid-mature variety is 227 days, which is earlier than that of the control Zhoumai 18 1 day. The seedlings are prostrate and vigorous, with narrow and curly leaves, dark green leaves, good cold resistance in winter, strong tillering ability before winter and average tillering rate.

Extended data:

Control scab:

1, select some disease-resistant varieties with good agronomic characters, such as Su Mai No.3, Su Mai No.2, Xiangmai 1, Young Mai No.4, Wanya No.2, Young Mai No.5, 158, Liaochun No.4, Zaomai No.5, Xingmai 17 and Xinong 88.

2. Agricultural prevention and control: rational irrigation and drainage, changing wetlands into ditches for drainage. After harvest, deep ploughing and stubble removal should be carried out to reduce the source of germs. Sow in time to avoid rain during flowering. Advocate the application of compost fermented by enzyme bacteria, adopt formula fertilization technology, apply fertilizer in time, avoid partial application of nitrogen fertilizer, and improve plant disease resistance. Generally, scab outbreaks are serious in rainy weather, and fungicides and pesticides should be sprayed in time after rain.

3. Seed soaking: soak the seeds with lime water before sowing. Methods See the head smut of wheat.

4. Chemical control: seed dressing with yield-increasing bacteria. Spraying seeds with 100- 150g solid microbial inoculum or 50ml liquid microbial inoculum every 6672, mixing, drying and planting. The key point of control is to prevent ear rot of wheat at flowering stage. First, grasp the application time: when the weather is fine and the temperature is high at the heading stage, the wheat will blossom at the same time of heading, and the best application time is at the early flowering stage (flowering 10 ~ 20%).
