日期:2021-01-13

BEIJING, Jan. 12 (Xinhua) -- Chinese scientists have bred a number of new varieties of major crops during the 13th Five-Year Plan period (2016-2020), providing solid support for the country's food security, the Chinese Academy of Agricultural Sciences (CAAS) said Tuesday.

The CAAS has made remarkable scientific and technological progress in staple crop breeding in recent years.

A series of significant achievements have been made in genome analysis, cloning of new genes and key breeding technologies for crops including wheat, rice, corn, soybean and coarse cereals, Wan Jianmin, vice president of the CAAS and also an academician of the Chinese Academy of Engineering, said at a press conference.

The research results have been published in top international journals such as Science, Nature, Nature Biotechnology and Nature Genetics, providing the theoretical basis and technical support for genetic improvement and precise breeding, Wan said.

According to him, the CAAS has made breakthroughs in breeding new crop varieties of staple crops that are of high quality, more tolerant for tough conditions and more suitable for machine reaping.

He also mentioned that a research center for protecting and utilizing crop germplasm resources has been set up, preserving the second-largest amount of crop germplasm resources in the world.
