Wuxing 2 (soybean original name: Jiguan 52)

Characteristics: purple flowers, brown hairs, oval leaves, sub-limited podding habits. The average growth period is 136.5 days, plant height is 94.0cm, effective branches are 1.8cm, number of effective pods per plant is 47.4, seeds per plant is 107.1, grain weight per plant is 19.8g, weight of 100 seeds is 19.2g. The soybean research center of Jilin Academy of Agricultural Sciences was inoculated and identified as SMV1 strain resistant to mosaic virus, mixed strain SMV with moderate resistance to mosaic virus, highly susceptible soybean heart borer and susceptible soybean cyst nematode. Good lodging resistance. The average crude protein content is 38.75%, and the crude fat content is 21.57%.

Yield performance: in 2002, participated in the northwest spring soybean variety regional trial, the average yield per mu was 213.38 kg, which was 1.55% higher than that of the control Jindou 19 (not significant); in 2003, the average yield per mu was 211.05 kg, which was 6.76% higher than that of the control Jindou 19 (extremely significant); the average yield per mu in the two-year regional trial was 212.22 kg, which was 4.08% higher than that of the control Jindou 19. Participated in the northwest spring soybean variety production experiment in 2003, the average yield per mu was 191.43 kg, which was 0.97% higher than that of the control Jindou 19.

Main points of cultivation techniques: 1. Sowing date: it can be carried out according to local climatic conditions, Gansu and Ningxia in mid-late April, Shaanxi at the end of April and early May, and spring sowing in Beijing, Tianjin and northern Hebei in the first and middle of May. 2. Density: the amount of machine sowing is 5.5-6.5 kg per mu, and that of manual sowing on demand is about 4 kg per mu. There are about 16000 seedlings per mu in the land with better fertility and 1.8-20000 seedlings per mu in the sandy soil with lower fertility. 3. Fertilizer and water management: except for special drought years, there is generally no watering at seedling stage. 5-7 kg / mu of pure nitrogen was applied at flowering stage combined with watering. Watering is determined according to soil moisture or rainfall during podding period. In case of drought during the grain filling period, it should be watered in time.

Approval opinion: after examination, this variety conforms to the national soybean variety approval standard and has passed the examination and approval. This variety belongs to the soybean variety with lack of lipoxygenase Ⅱ, low fishy flavor and high oil. It is suitable for spring sowing in the fields with high fertility in northern Shaanxi, central Hebei, eastern and central Gansu.
