Yellow seed coat, light brown hilum, flat oval seeds. Good disease resistance and lodging resistance. Average crude protein content 39.44%, crude fat content 22.12%.

Yield performance: In 2002, it participated in the summer soybean variety regional trial in the central Huang-Huai-Hai region, with an average yield of 166.52 kg per mu, an increase of 7.86% over the control Ludou 11 (highly significant); in 2003, in the continued trial, the average yield was 190.64 kg per mu, an increase of 7.28% over the control Ludou 11 (highly significant); the two-year regional trial average yield was 178.58 kg per mu, an increase of 7.55% over the control Ludou 11. In 2003, it participated in the summer soybean variety production trial in the central Huang-Huai-Hai region, with an average yield of 176.94 kg per mu, an increase of 8.20% over the control Ludou 11.

Key cultivation techniques: 1. Density: Generally maintain 15,000-17,000 plants per mu. 2. Sow when there is sufficient soil moisture or irrigate to create adequate moisture before sowing to ensure full emergence. Irrigate during drought at the branching stage, flowering and podding stage, and seed-filling stage. 3. Suitable for planting in fertile and relatively fertile land. At the seedling stage and early flowering stage, apply 10-20 kg per mu of diammonium phosphate or compound fertilizer as a topdressing.

Approval opinion: Upon review, this variety meets the national soybean variety approval standards and has passed approval. This variety is a late-maturing summer soybean variety and is resistant to soybean cyst nematode. It is suitable for planting in central and southern Shandong, northern Henan, southern Hebei, southern Shanxi, and the Guanzhong Plain of Shaanxi.
