Seed coat yellow, brown navel, round. The lodging resistance is strong, and the disease resistance is general. The average crude protein content is 42.26%, and the crude fat content is 18.45%.

Yield performance: in 2002, participated in the regional trial of summer soybean varieties in Huang-Huai-Hai, the average yield per mu was 184.37 kg, which was 19.42% higher than that of the control Ludou 11 (extremely significant); in 2003, the average yield per mu was 191.34 kg, which was 7.68% higher than that of the control Ludou 11 (extremely significant). The average yield per mu in the two-year regional trial was 187.86 kg, 13.13% higher than that of the control Ludou 11. In 2003, he participated in the production experiment of summer soybean varieties in Huang-Huai-Hai, and the average yield per mu was 171.84 kg, which was 5.08% higher than that of the control Ludou 11.

Main points of cultivation techniques: 1. Suitable sowing date: in the first and middle of June, wheat ridge interplanting in the north and west of Henan can be sown 10 days before wheat harvest. The sowing rate per mu is 4-5 kg, the row spacing is about 40 cm, the plant spacing is 13-15 cm, and there are 1-15000 seedlings per mu. 2. Fertilizer and water management: this variety likes fertilizer and should apply more base fertilizer and appropriate amount of topdressing. Application of calcium magnesium phosphate fertilizer 40-50 kg per mu, or diammonium 10 kg, topdressing urea 5 kg at the early flowering stage can also be foliar spraying fertilizer. Due to the concentrated flowering period and more flowering of this variety, drought watering at flowering and pod stage is the key to high yield. 3. The variety has good defoliation at maturity, consistent maturity and strong resistance to pod cracking, and can be harvested after the plant is fully mature and the grain is dry, so as not to affect the appearance and quality of the early harvest.

Approval opinion: after examination, this variety conforms to the national soybean variety approval standard and has passed the examination and approval. This variety is a mid-mature variety sown in summer and is suitable to be planted in north-central Henan, southern Hebei, southern Shanxi and Guanzhong plain of Shaanxi province.
