The new strain of salt-tolerant soybeans has completed the actual harvest and measured yield, and the mu yield has reached more than 270 kg

The reporter learned from the Chinese Academy of Sciences that the new salt-tolerant soybean strain "Kedou 35", cultivated by Tian Zhixi, a researcher at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, completed field acceptance and production
testing in Dongying, Shandong on October 15.
The production test results show that the yield of "Kedou 35" is more than 270 kg per mu, which is a significant increase
compared with the average mu yield of similar varieties in China.

"Soybeans are an important grain, oil and feed crop, and China has a large number of saline-alkali land with agricultural utilization prospects, and cultivating new varieties of salt-tolerant soybeans is an important new direction
to improve China's soybean production capacity.
" Tian Zhixi said that "Kedou 35" has outstanding performance in saline-alkali land and is expected to play an important role
in using saline-alkali land to improve soybean production capacity.

According to reports, in order to cultivate new salt-tolerant soybean strains, the research team carried out high-intensity salt-tolerant screening and community tests in Dongying for five consecutive years, and screened and obtained 68 salt-tolerant new germplasms from more than 13,000 soybean germplasm materials, of which 25 were particularly excellent
.
On this basis, the team cultivated "Kedou 35"
.

In June 2022, the research team carried out 30 mu continuous demonstration planting of "Kedou 35" in saline-alkali plots with soil salinity of 4.
5‰ to 6.
5‰ using a completely natural rainfed planting
method.

The production testing expert group believes that "Kedou 35" has strong stress resistance, especially outstanding in terms of salinity and drought resistance at the seedling stage and flood resistance in the later stage, and the appearance and quality of soybeans are excellent, and it is recommended to increase the demonstration planting efforts in the saline-alkali land of the Bohai Rim and accelerate the approval and promotion
