14 new cotton varieties resistant to Verticillium wilt were bred

On September 1, the Agricultural products processing Institute of the Chinese Academy of Agricultural Sciences, the Plant Protection Institute of the Chinese Academy of Agricultural Sciences and Henan Zhongyuan Zhongnong improved Variety Co., Ltd. jointly hosted the * * cotton disease resistance and high yield demonstration field exhibition. After more than 20 years of tackling key problems, the research group headed by Dai Xiaofeng, director of the Agricultural products processing Institute of the Chinese Academy of Agricultural Sciences, cultivated 14 new cotton varieties resistant to Verticillium wilt, such as Zhongzhu 2, Xinluzhong 46, Xinzhiza 2, etc. Over the past 10 years, the cumulative promotion of more than 79.9 million mu has achieved economic benefits of 15.859 billion yuan.

Cotton Verticillium dahliae occurred again in China, the annual yield loss was more than 15%, and the damaged area reached 3 million hectares in 2003. the breeding of resistance to Verticillium wilt is a worldwide problem. "of these 14 varieties, 7 have been approved by the state and 7 by the provincial level. Xinzhi No. 5 was recognized by the Ministry of Agriculture as the leading variety of cotton in China in 2016, while Zhongzhimian No. 2 and Xinzhiza No. 2 were identified as the leading varieties by many provinces for many years. " Dai Xiaofeng said.

Zhu Yuxian, academician of the Chinese Academy of Sciences, Yu Shuxun, academician of the Academy of Engineering, and other experts believe that the disease resistance identification technology of the project and the breeding technology of new cotton varieties resistant to Verticillium wilt occupy the leading position in the world. In 2013, Dai Xiaofeng was awarded the Golden Kangaroo Invention Award by her international counterpart WORLD INNOVATION FORUM. In addition to Dai Xiaofeng, academician Yuan Longping and researcher Zhao Jiuran, founder of corn standard DNA fingerprint database, won the award.
