盈江县高山大白菜根肿菌生理小种鉴定及抗源筛选
|
摘要
采用Williams鉴别系统对云南省盈江县高山大白菜产区采集的根肿菌进行鉴定,4个鉴别寄主均表现为感病,病情指数分别为21、33、28、30,说明该根肿菌为4号生理小种。采用菌土法接种盈江根肿菌,对18个抗根肿病大白菜品种进行抗性鉴定,其中6个品种发病率和病情指数均为0,对盈江根肿菌表现免疫;2个品种病情指数<10,表现抗病,可以作为该病区大白菜新品种选育的抗性遗传资源。
The Williams identification system was adopted to identify the Plasmodiophora brassicae collected from the Chinese cabbage producing area at the mountainous areas in Yingjiang County,Yunnan Province.The 4 differential hosts all showed that they were susceptible,and the disease index was 21、33、28、30,respectively,indicating that fungus was physiological race No.4.The resistance of 18 Chinese cabbage cultivars from home and abroad was identified by planting on fungal soil method.The results showed that the incidence and disease indexes of 6 varieties were 0,and they were immune to Yingjiang Plasmodiophora brassicae.The disease index of 2 varieties were < 10,indicating they were resistant to Yingjiang Plasmodiophora brassicae.They could be used as resistant genetic resources for selecting new Chinese cabbage varieties for this disease.
