[Main traits of varieties]:

The plant is semi-compact, with high plant and ear positions. The seedling leaf sheath is purple, the number of adult leaves is about 21, and there are 6 to 7 leaves on the panicle. The tassels have 5 to 7 branches, the anthers are light purple, and the filaments are red. The ear is cone-shaped, bracts are better coated, the cob is red, the grain is yellow, and the horse tooth type. In the regional test, the plant height was 296.6 cm, the ear height was 127.6 cm, and the empty stalk rate was 0.2%. The ear length is 19.3 cm, the ear thickness is 5.0 cm, the bald tip length is 0.8 cm, the number of rows of ears is 16.5, the number of rows of grains is 37.9, the thousand-grain weight is 326.0 grams, the seed yield rate of dry ears is 84.3%, and the growth period is 114.2 days. Participated in the regional trial of the green channel varieties of the corn hills and plains in Hubei Province from 2018 to 2019. The quality was determined by the Cereal and Product Quality Supervision and Inspection Center of the Ministry of Agriculture and Rural Affairs (Harbin), the bulk density was 760 g/l, and the crude protein (dry basis) content was 10.63% , Crude fat (dry basis) content is 3.77%, crude starch (dry basis) content is 75.31%.

[Adaptability]:

The average yield per mu in the two-year regional test in Hubei Province was 690.53 kg, which was 10.42% higher than the control Yidan 629. Among them: In 2018, the yield per mu was 620.53 kg, which was 9.49% higher than Yidan 629; the yield in 2019 was 760.53 kg per mu, which was 11.19% higher than Yidan 629. Field large spot disease is grade 5, small spot disease is grade 5, rust disease is grade 3, ear rot is grade 3, grade 9 sheath blight disease plant rate is 0.2%, and stem rot disease plant rate is 0.5%. The field lodging (discount) rate is 0.8%.

The average yield per mu in the 7 pilot projects in Sichuan Province in 2020 is 573.6 kg, which is 7.1% higher than the control single 30; the rate of increase is 100%; the average growth period is 118 days, which is 1 day earlier than the control single 30. Resistance identification: resistance to large leaf spot, sheath blight, medium resistance to small leaf spot, ear rot, gray spot, and high susceptibility to stem rot.

[Main cultivation measures]:

1. Plant seeds at the right time and plant them closely. Sowing from late March to early April, about 3,500 plants per mu for single cropping. 2. Scientific fertilization. Apply plantar fertilizer, apply seedling fertilizer early, apply jointing fertilizer, and reapply ear fertilizer. 3. Strengthen field management. Pay attention to squatting seedlings, timely cultivation, drought resistance, drainage, and spraying growth regulators to control plant height and prevent lodging. 4. Prevent pests and diseases. Pay attention to the prevention and control of large spot disease, small spot disease, sheath blight, stem rot, cutworm, armyworm, armyworm, corn borer and other diseases and insect pests.

[Suitable area for planting]:

It is suitable for planting spring maize in the hilly and plain areas of Hubei Province. Spring corn type area in Pingba hilly area in Sichuan Province.
