my country's bean breeding pollen low temperature preservation key technology has achieved new breakthroughs

The reporter learned from the Heilongjiang Academy of Agricultural Sciences Heihe Branch on the 4th that the Institute of Craft Sciences of the Chinese Academy of Agricultural Sciences cooperated with Heilongjiang Academy of Agricultural Sciences Heihe Branch to study the key technologies of low -temperature preservation of large bean flour in my country and achieved new breakthroughs. This research achievement achieves soybean pollen during different seasons and different places, breaking the time and space obstacles of soybean pollen applications, and providing technical support for the achievement of soybeans and engineering breeding.

According to Lu Wencheng, a researcher at the Heilong Academy of Agricultural Sciences of Heilongjiang Provincial Academy of Agricultural Sciences, artificial hybridization is still the main way for soybean breeding to create mutation. Hybridization generally requires the consistent flowering period of parents, and the planting location is similar to the smooth progress of the planting location. To a certain extent, soybean breeding can be restricted by pro -pro -pro -pro -based range, and the genetic basis for breeding varieties is narrow. Maintaining soybean pollen vitality through low temperature is an effective way to overcome the above problems.

Researchers use soybean flowers as ultra -low temperature preservation materials, which clarifies the development and collection time suitable for soybean flowers that are suitable for ultra -low -temperature preservation. It optimizes the key technical links that affect the low temperature preservation effect of pollen before freezing, freezing methods, and freezing methods. Maintain and efficiently use the ultra -low temperature preservation technology of soybean pollen.

The research team uses this technology to keep soybean pollen highly activated for a long time, and realize the application of soybean pollen in Heihe in Heihe. Under the blessing of dry ice, soybean pollen was transported from Heihe to Beijing through express delivery. After 3 days, it achieved a different application of pollen in different places after nearly 2,000 kilometers.

Han Tianfu, chief scientist at the National Soybean Industry Technology System and researcher at the Institute of Crop Sciences of the Chinese Academy of Agricultural Sciences, said that the key technologies of pollen low -temperature preservation have made breakthroughs, and it is of great significance to make up for the shortcomings of the key technology of large soybean breeding in my country.
