日前,由中国农科院农产品加工研究所、植保所、南京农大等单位共同完成的“棉花抗黄萎病中植棉系列新品种选育及应用”课题,攻克黄萎病这一世界难题。据课题组组长戴小枫介绍,棉花黄萎病是制约棉花生产的关键因素之一,常年导致棉花产量损失10%~15%,被称为棉花的“癌症”。课题组通过26年的努力,终于突破了以往田间抗黄萎病鉴定结果不准确、稳定性和重现性差,缺乏有效利用的抗原和抗性快速检测技术等技术关键,创建人工高压复合动态病圃筛选与分子标记辅助聚合抗病育种技术体系,创
Recently, by the Chinese Academy of Agricultural Sciences Institute of Agricultural Products Processing, Institute of Plant Protection, Nanjing Agricultural University and other units jointly completed the “Cotton Verticillium wilt resistant cotton varieties in the series breeding and application of” subject to overcome the world of Verticillium wilt problem. According to Dai Xiaofeng, project leader, cotton is one of the key factors restricting cotton production. It causes 10% -15% loss of cotton production all the year round and is called “cancer” of cotton. After 26 years of efforts, the research team finally broke through the key technologies of anti-detection of Verticillium wilt in the field, such as inaccurate identification, poor stability and reproducibility, rapid detection of antigens and resistance, and the establishment of artificial high-pressure complex dynamic disease Nursery screening and molecular marker-assisted polymerization disease-resistant breeding technology system, a record
