(1) Variety source: it is a variant superior plant selected by the Oil Institute of Chinese Academy of Agricultural Sciences introduced by Nanchong Institute of Agricultural Sciences from Sichuan Academy of Agricultural Sciences in 1989 (original code 92001-03).

(2) characteristics: the plant height was about 60cm, and the whole plant was born for 113d. Main stem 13.4 nodes, 2.2-3.7 branches, leaves lanceolate, medium size, dark green. Purple flowers, gray hairs, limited podding habits. The pods were dense, the number of pods per plant was 78.3 pods, and the pods were evenly distributed above and below, with 1.9 seeds per pod. The pod is grayish brown, the initial pod is high 12cm, the grain is oval, the seed coat is yellow, the glossy navel is light yellow, the 100-grain weight is 21.4g, and the intact grain rate is 98.9%. In 1999, the provincial academy of agricultural sciences showed that the grain contained 43.1% protein and 21.8% crude fat. The susceptible virus disease was 0.3 grade and the lodging degree was 0.3 grade in the field.

(3) yield performance: the average yield per mu at 11:00 in the provincial regional test in 1997-1998 was 10.8% higher than that of the control Xidou 3, and the average yield per mu at 3 points in the production test in 1998 was 179.7k9, 19.8% higher than that of the control Xidou 3.

(4) cultivation key points: ⑦ sowing time: spring sowing in early and mid-April, summer sowing in mid-May and late May, autumn sowing from July 10th to August 5th. ② density: 1.2-14000 plants per mu in spring and summer and 2.4-26000 plants per mu in autumn. Intercropping with red clover and peanut, planting 0.5-7000 plants per mu. ③ fertilization: heavy application of base fertilizer, early application of seedling fertilizer, base fertilizer with 25-30kg calcium superphosphate or human and animal fertilizer. ④ field management: pay attention to the control of soil silkworms in spring sowing and crickets and caterpillars in autumn sowing seedlings. ⑤ harvested in time to ensure the quality of seeds.

(5) suitable planting area: suitable for soybean producing area, net, intercropping and intercropping in the whole province.
