Growing Techniques 0 views
Characteristics: Purple flowers, brown pubescence, ovate leaves, sub-indeterminate podding habit. Average growth period 136.5 days, plant height 94.0 cm, 1.8 effective branches, 47.4 effective pods per plant, 107.1 seeds per plant, 19.8 g seed weight per plant, 19.2 g 100-seed weight. According to inoculation identification by the Soybean Research Center of the Jilin Academy of Agricultural Sciences, it is resistant to soybean mosaic virus (SMV) strain 1, moderately resistant to mixed SMV strains, highly susceptible to soybean pod borer, and susceptible to soybean cyst nematode. Resistant

Characteristics: Purple flowers, brown pubescence, ovate leaves, sub-indeterminate podding habit. Average growth period 136.5 days, plant height 94.0 cm, 1.8 effective branches, 47.4 effective pods per plant, 107.1 seeds per plant, 19.8 g seed weight per plant, 19.2 g 100-seed weight. According to inoculation identification by the Soybean Research Center of the Jilin Academy of Agricultural Sciences, it is resistant to soybean mosaic virus (SMV) strain 1, moderately resistant to mixed SMV strains, highly susceptible to soybean pod borer, and susceptible to soybean cyst nematode. Good lodging resistance. Average crude protein content 38.75%, crude fat content 21.57%.

Yield performance: In 2002, it participated in the Northwest Spring Soybean Variety Regional Trial, with an average yield of 213.38 kg per mu, 1.55% higher than the control Jindou No. 19 (not significant); in 2003, in the continued trial, the average yield was 211.05 kg per mu, 6.76% higher than the control Jindou No. 19 (extremely significant); the two-year regional trial average yield was 212.22 kg per mu, 4.08% higher than the control Jindou No. 19. In 2003, it participated in the Northwest Spring Soybean Variety Production Trial, with an average yield of 191.43 kg per mu, 0.97% higher than the control Jindou No. 19.

Key cultivation techniques: 1. Sowing time: It can be carried out according to local climatic conditions. In Gansu and Ningxia, mid-to-late April; in Shaanxi, late April to early May; in the spring sowing areas of Beijing, Tianjin, and northern Hebei, sowing in early-to-mid May is appropriate. 2. Density: Mechanical sowing rate 5.5-6.5 kg per mu, manual dibbling about 4 kg per mu. For plots with better fertility, retain about 16,000 plants per mu; for lower-fertility sandy land, retain 18,000-20,000 plants per mu. 3. Fertilizer and water management: Except in special drought years, generally do not irrigate at the seedling stage. At the flowering stage, apply 5-7 kg of pure nitrogen per mu together with irrigation. At the podding stage, determine irrigation based on soil moisture or rainfall. During the seed-filling stage, irrigate promptly in case of drought.

Approval opinion: Upon review, this variety meets the national soybean variety approval standards and has passed approval. This variety is a lipoxygenase II-deficient, low-beany-flavor, high-oil soybean variety, suitable for spring sowing in plots with higher fertility levels in northern Shaanxi, central Hebei, and eastern and central Gansu.
