There are about 6 upper leaves, 8-19 branches on the tassel, light red anthers and light red filaments. The ear is cone-shaped, the bracts are more intact, the cob is white, the grain is yellow, and the horse tooth type. In the regional test, the plant height is 299.7 cm, the ear height is 130.2 cm, the empty stalk rate is 0.3%, the ear length is 18.4 cm, the ear thickness is 5.4 cm, the bald tip length is 0.5 cm, the number of ear rows is 18.8, the number of rows is 35.2, and the thousand-grain weight is 343.6 grams. The seed yield rate from dry ears was 87.4%, and the growth period was 130.7 days.

[Adaptability]:

Participated in the regional test of maize mountain group varieties in Hubei Province from 2015 to 2016. The quality was determined by the Grain Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture. The bulk density is 777 g/l, the crude protein (dry basis) content is 10.44%, and the crude fat (dry basis) content is 4.67 %, the crude starch (dry basis) content is 74.22%. The average yield per mu in the two-year regional test was 724.19 kg, which was 8.22% higher than the control Shuangyu 919. Among them: the yield per mu in 2015 was 779.47 kg, which was an increase of 7.17% compared with Shuangyu 919; the yield of 2016 was 668.91 kg per mu, which was 9.46% higher than that of Shuangyu 919. Field large spot disease is grade 3, small spot disease is grade 3, gray spot disease is grade 5, rust disease is grade 3, stem rot disease plant rate is 0.5%, and grade 9 sheath blight disease plant rate is 0.6%. The field lodging (discount) rate was 2.7%.

[Main cultivation measures]:

1. Plant seeds at the right time and plant them closely. Sowing in mid-April, about 3,200 plants per mu for single cropping. 2. Scientific fertilization. Apply plantar fertilizer, formula fertilization, see seedling topdressing ear fertilizer. 3. Strengthen field management. Pay attention to squatting seedlings, timely cultivating, drought resistance and drainage, and prevention of lodging. 4. Pay attention to the prevention and control of gray spot, brown spot, stem rot, ear rot, large spot, small spot, rust, cutworm, corn borer and other diseases and insect pests.

[Suitable area for planting]:

It is suitable for planting spring maize in the low mountain and two high mountain areas of Hubei Province. Changsha City, Hengyang City, Xiangtan City, Shaoyang City, Yueyang City, Changde City, Zhangjiajie City, Yiyang City, Chenzhou City, Yongzhou City, Huaihua City, Loudi City, Xiangxi Autonomous Prefecture introduced the species. Ten prefectures in Yunnan Province, Zhaotong City, Kunming City, Lijiang City, Dehong Prefecture, Qujing City, Chuxiong Prefecture, Dali Prefecture, Baoshan City, Lincang City, and Pu'er City are introduced and planted between 1,000 and 2,000 meters above sea level.
