Analysis resistance breeding progression of Brassica napus in Southwest China based on evaluation of disease resistance
摘要
Abstract
To elucidate the progression of the resistance breeding and utilization of Brassica napus against Sclero-tinia stem rot and clubroot,disease resistance of new varieties/breeding materials and main varieties in Southwest Chi-na(Yunnan,Guizhou,Sichuan,Chongqing)was evaluated by artificial inoculation and natural disease nursery induc-tion for 7 consecutive years.The results showed that 5 new varieties(OM109,Huayuaza 706R,Nanyou 1958R,Chuan-nong you 2251 and Chuannong you 2252)with high resistance to clubroot were obtained,3 new varieties and 16 breed-ing materials with high resistance to clubroot were obtained in 2023,and the breeding progress against clubroot was the most significant.However,there was no significant breakthrough in the breeding of new varieties resistant to Scler-otinia stem rot.The resistance types were mainly low antimicrobial sclerotinia,reaching 43.69%.The resistance of me-dium and high Sclerotinia stem rot resistant varieties was unstable,and no high varieties were identified during two consecutive years.The main varieties of Sclerotinia stem rot and clubroot tracking and monitoring found that the dis-ease-resistant varieties were used less,and there were no varieties that were simultaneously resistant to Sclerotinia stem rot and clubroot.The results of this study directly analyzed the effectiveness of B.napus resistance breeding,and were expected to provide theoretical reference for B.napus resistance breeding and its utilization.关键词
