[Main traits of varieties]:

The plant is semi-compact, with moderate plant and ear positions. The leaf sheath of the seedling is purple, the number of adult leaves is about 20, and there are about 6 leaves on the panicle. The tassels have 8 to 19 branches, the anthers are light red, and the filaments are light 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 is 305.5 cm, the ear height is 137.9 cm, the empty stalk rate is 1.1%, the ear length is 19.2 cm, the ear thickness is 5.5 cm, the bald tip length is 0.6 cm, the number of ear rows is 18.0, the number of rows is 37.6, and the thousand-grain weight is 350.3 grams. The seed yield rate from dry ears was 85.3%, and the growth period was 131.6 days. For quality determination, the bulk density is 758 g/L, the crude protein (dry basis) content is 9.72%, the crude fat (dry basis) content is 3.97%, and the crude starch (dry basis) content is 74.58%.

[Adaptability]:

From 2016 to 2017, we participated in the regional trial of corn mountain group varieties in Hubei Province. The average yield per mu in the two-year regional trial was 714.43 kg, which was 11.07% higher than the control Shuangyu 919. Among them, the yield per mu in 2016 was 671.71 kg, which was 5.74% higher than that of Shuangyu 919; the yield in 2017 was 757.14 kg per mu, which was 16.27% higher than that of Shuangyu 919. Field gray spot disease is grade 3, ear rot is grade 3, sheath blight is grade 9 diseased plants rate is 2.3%, stem rot diseased plants rate is 1.5%. The field lodging (discount) rate is 2.8%.

[Main cultivation measures]:

Plant timely and reasonably close planting. Sowing in early and mid-April, about 3000 plants per mu for single cropping.

Fertilize scientifically. Apply plantar fertilizer, lightly apply seedling fertilizer, and watch seedling topdressing ear fertilizer.

Strengthen field management. Pay attention to squatting seedlings, timely cultivating, drought resistance and drainage, and prevention of lodging.

Prevent pests and diseases. Pay attention to the prevention and control of gray spot, ear rot, cutworm, corn borer and other diseases and insect pests.

[Suitable area for planting]:

It is suitable for planting spring maize in low mountains and two high mountains below 1000 meters above sea level in Hubei Province. Introduced in Hunan Province. It is planted in corn areas with an altitude of 1,000 to 2,000 meters in Zhaotong City, Kunming City, Lijiang City, Dehong Prefecture, Qujing City, Chuxiong Prefecture, Dali Prefecture, Baoshan City, Lincang City, and Pu'er City in Yunnan Province.
