No fishy soybean 93102-1
Soybean lipoxidase LOX catalyzes the oxidation of unsaturated fatty acids to produce aldehydes, ketones and other harmful substances, which makes soybean produce fishy smell and affects the development and utilization of soybean products. Scientists and technicians of crop Research Institute of Shandong Academy of Agricultural Sciences introduced LOX deletion materials in 1991, and focused on the genetic improvement of LOX deletion. The first soybean strain, 93102-1, which has application value, has been bred in China. The yield is about 200kg per 667m2 (1 mu), which is more than 60kg higher than that of the imported material, and the weight of 100 grains is about 18g, which is 6g higher than that of the imported material. It has excellent quality, disease resistance, lodging resistance and no premature senility. It passed the expert appraisal organized by Shandong Science and Technology Commission at the end of 1999 and reached the leading level in China.

Why the soybean root nodule is few and small?
There are nodules on the root of soybean, which can be used for symbiotic nitrogen fixation, which is an important source of nitrogen for legume crops. But in actual production, sometimes the root nodules of soybean are few and small, what is the cause of this? Expert: when you encounter particularly serious symptoms, you should first think that it may be caused by the lack of trace element molybdenum. Because molybdenum is an essential trace element for nitrogen fixation in root nodules of legume crops, the absolute content of general crops is 1/1000000, while the molybdenum requirement of soybean is dozens of times higher than that of other crops. The main function of molybdenum is to promote the shape of soybean nodules.
