What are the latest high-yield soybean seed varieties?

Soybean, commonly known as yellow bean, is an annual herbaceous plant of the genus Glycine in the Fabaceae family, native to China, cultivated throughout our country, and is also one of China's important food crops, and is also widely cultivated around the world, with a cultivation history of five thousand years, most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein. Now let's take a look together at what high-yield soybean seeds there are!

Kendou No. 40

[Characteristics]Main stem pods predominate, plant height about 70 cm. Pointed leaves, purple flowers, gray pubescence, pods brown. Seeds round, seed coat yellow, glossy, yellow hilum, 100-seed weight 17.1 g. In suitable areas, growth period about 117 days, requiring about 2350°C active accumulated temperature. Field performance shows disease resistance and lodging resistance; inoculation identification shows resistance to gray leaf spot, moderate resistance to soybean mosaic virus strain 1, and susceptibility to strain 3.

[Yield]From 2011 to 2012, participated in the regional trial of the northern spring soybean medium-early maturity group, with an average yield of 2833.5 kg per hectare, 2.8% higher than the control variety. In the 2013 production trial, the average yield was 3010.5 kg per hectare, 11.1% higher than the control variety.

[Cultivation]Generally sown in early to mid-May; with ridge-three cultivation, maintain 250,000 to 350,000 plants per hectare; with dense planting cultivation, 350,000 to 400,000 plants. Generally apply 150 kg diammonium phosphate, 50 to 75 kg potassium sulfate, and 40 to 50 kg urea per hectare, and spray soybean-specific foliar fertilizer 1 to 2 times each at the flowering and podding stages.

Zhonghuang No. 35

[Characteristics]Summer sowing growth period about 100 days, spring sowing 121 days. Plant height 75 to 90 cm, effective branch number 1 to 2, elliptical leaves, white flowers, gray hairs, mature pod color brown, podding habit semi-determinate, seed shape round, yellow seed coat, yellow hilum, 100-seed weight 18 to 22 g. Moderately resistant to soybean mosaic virus disease and gray leaf spot, moderately susceptible to soybean cyst nematode disease.

[Yield]In 2004, participated in the summer soybean variety regional trial of the northern Huang-Huai-Hai region, with an average yield of 206.0 kg per mu, 19.3% higher than the early-maturing control 18. In the 2005 continued trial, the average yield was 204.3 kg per mu, 5.6% higher than the control Jidou 12. The two-year regional trial average yield was 205.1 kg per mu. In the 2005 production trial, the average yield was 219.1 kg per mu, 5.8% higher than the control Jidou 12.

[Cultivation]Before sowing, apply 2000 to 3000 kg decomposed organic fertilizer per mu; at sowing, apply phosphorus and potassium fertilizer as seed fertilizer; sowing rate 4 to 5 kg per mu; maintain 12,000 to 16,000 plants per mu; pay attention to drought prevention at the branching stage, flowering and podding stage, and seed-filling stage.

Shengdou No. 5

[Characteristics]Determinate podding habit, compact plant type. Growth period 106 days, 3 days later maturing than the control Hedou No. 12. Plant height 79.6 cm, effective branches 2.3, main stem 16 nodes, round leaves, white flowers, brown hairs, leaves drop, pods do not shatter, seeds per plant 104, seeds elliptical, seed coat yellow, glossy, hilum black, 100-seed weight 19.3 g.

[Yield]In the 2012 to 2013 provincial summer soybean variety regional trial, the two-year average yield was 224.4 kg per mu, 7.7% higher than the control Hedou No. 12; in the 2014 production trial, the average yield was 244.3 kg per mu, 8.4% higher than the control Hedou No. 12.

[Cultivation]The suitable density is 13,000 to 15,000 plants per mu; other management measures are the same as general fields; planted and utilized as a summer soybean variety in central Shandong, southern Shandong, and southwestern Shandong regions.

Jindou No. 23

[Characteristics]Plant height 90 to 100 cm, plant type compact, leaves round, leaf color dark green, brown pubescence, white flowers, indeterminate podding habit. Seed coat yellow, glossy, black hilum. 100-seed weight 21 to 23 g, protein content 40.11%, fat 18.84%. Spring sowing growth period 128 to 133 days; plants grow vigorously, many branches, dense pods, early seed filling, large seeds. Strong drought resistance and virus resistance, tolerant to red spider mites.

[Yield]From 1999 to 2000, participated in the national regional trial, with an average yield of 168.6 kg per mu, 11.5% higher than the control Tiefeng No. 27. In the 2000 national regional trial, the average yield was 169.7 kg per mu, 1.9% higher than the control. In the 2000 production trial, the average yield was 193.2 kg per mu, 2.4% higher than the control.

[Cultivation]For spring sowing, sow from late April to early May, sowing rate 4 to 6 kg per mu, planting density 8000 to 10,000 plants per mu. For replanting after wheat stubble, sow from early to mid-June, sowing rate about 7.5 kg per mu, leaving about 16,000 seedlings per mu, and pay attention to sowing in time and while soil moisture is sufficient.
