选用 3套同核异质水稻不育系及其相应的保持系 ,以及生产上推广应用的 13个水稻主栽品种 ,于水稻孕穗期接种具有不同致病力的 4个水稻细菌性条斑病菌菌株。不育胞质的抗病性鉴定结果表明 ,不同胞质类型的不育系之间抗病性差异明显 ,均比其同名保持系感病 ,其中野败型不育胞质 (W汕A、W协A)高感细条病 ,T型胞质 (T新A、T协A)对细条病的抗性较好。但在G型 (如G新A等 )少数不育胞质与条斑病菌如Syt等少数菌株的互作中 ,表现出明显的胞质效应 ,不育胞质较之正常胞质更感病。水稻品种抗性鉴定结果表明 ,江苏省水稻细条病发生地区目前推广的13个主栽品种中 ,武育粳 3号、镇稻 88等 6个粳稻品种表现为高抗 ,5个籼型品种和 1个粳稻品种高感条斑病。根据调查 ,在病区种植高抗品种完全可以控制水稻细条病的危害
Three sets of homologous-heterologous rice CMS lines and their corresponding maintainer lines were selected, and 13 rice cultivars promoted and used in production were selected and inoculated with four rice bacterial leaf streak fungi Strain. The results of the resistance evaluation of sterile cytoplasm showed that the resistance of different cytoplasmic male sterile lines was significantly different from that of the same cytoplasmic male sterile line. Among them, the wild-type sterile cytoplasm (Wanshan A, W Association A) high sense of thin strip disease, T-type cytoplasm (T New A, T Association A) resistance to Sliver Strip disease is better. However, in G type (such as G new A) a small number of sterile cytoplasm and Streak pathogens such as Syt and a few strains of interaction, showed a significant cytoplasmic effect, sterile cytoplasm more susceptible than normal cytoplasm . Among the 13 main cultivars popularized in rice stripe disease area of Jiangsu Province, six japonica cultivars including Wuyujing 3 and Zhendao 88 showed high resistance and 5 indica varieties One japonica variety High susceptible leaf spot. According to the survey, cultivation of high resistance varieties in the ward can completely control the harm of rice stripe disease
