Nenfeng 16 (soybean)

Nenfeng 16, a new soybean variety, was crossed sexually by Nenjiang Agricultural Research Institute of Heilongjiang Academy of Agricultural Sciences in 1992 with Nen 8422-3 as female parent and Nen 79705-16 as male parent. The hybrid number was 9232, and the F1 generation was planted in 1993. In the winter of that year, the southern propagation was carried out, F3 generation was planted in 1994, and F4 was selected in 1995. The code name is Nen 9232-8. In-house identification, quality comparison test and remote identification test were carried out from 1996 to 1997. Participated in the regional test in Heilongjiang Province from 1998 to 1999, and carried out the production test in 2000.

The variety has pointed leaves, white flowers, downy gray, sub-limited podding habits, main stem type, plant height 80~100cm. The culms are strong, the internodes are short, the pods are dense, there are more than three or four pods, the seeds are round, and the weight of 100 seeds is about 27g. Testa yellow, glossy, navel yellow. The growth period is 118-120 days, and the active accumulated temperature is 2400 ℃. The protein content is 41.19% and the fat content is 20.11%. Resistant to gray spot, preferring fat and water.

The average yield identified in the institute was 2632.6Kg/hm2, which was 14.0% higher than that of the control variety Nenfeng 14. In 1997, the average yield was 3204.8kg/hm2, which was 16.3% higher than that of the control variety Nenfeng 14. In 1998, all the four regional trials in the province increased the yield, and the average yield was 2200kg/hm2, which was 10.5% higher than that of the control variety Nenfeng 14.

All the four regional trials in the province increased the yield, with an average yield of 2464.8Kg/hm2, 13.8% higher than the control variety Nenfeng 14. In the regional trial from 1998 to 1999, the average yield was 2332kg/hm2, which was 12.2% higher than that of the control variety Nenfeng 14.

In the production experiment, the yield was increased at all 5 points, and the average yield was 2073.2kg/hm2, which was 17.6% higher than that of the control variety Nenfeng 14.

The variety has a fat content of 20.11% and a protein content of 41.19%, which is a double-high variety. This year, Wuyi Village, Xinhua Township, Suihua City, introduced this variety 6000kg and registered it as a "May Day" soybean in the country, ready to export to Japan. This variety has large grains, a hundred-grain weight of about 27g and good commerciality. it is suitable for puffed food and exported to South Korea. In addition, because of its large grains, this variety is suitable for making edamame beans. The application prospect of Nenfeng 16 is very promising. This variety has the advantages of good quality, high yield, strong disease resistance and wide adaptability. over the past few years, through large-scale experiments and demonstrations, it has been deeply loved by farmers and welcomed by seed departments, and it is expected that its extension area will continue to expand. will create great economic and social benefits.

Region and technology this variety prefers fertilizer and water and has great potential to increase yield under good fertilizer and water conditions. It is appropriate to choose middle-and high-grade fertility plots and sow early at the right time. Plant in the suitable area of Heilongjiang Province and sow in early May. Organic fertilizer 15t/hm2, diammonium phosphate 150~225kg/hm2 and urea 150kg/hm2 were applied. The general seedling protection is 260000 ~ 280000 plants / hm2, and the amount of seed used is 60~8Okg/hm2. This variety is suitable for planting in the first accumulated temperate zone and the second accumulated temperate zone in Heilongjiang.
