摘要
为探明茄子抗青枯病的遗传机制,以高感青枯病品种北京六叶茄064,马来西亚半栽培高抗青枯病品种S3及其F2代为材料,采用针刺叶片法和伤根灌注法进行温室苗期人工接种鉴定,对供试材料的抗青枯病特性进行了遗传分析研究.结果表明接种鉴定方法以伤根灌注法较为适宜;抗病亲本材料S3的抗病基因由一对显性基因控制.为定位和克隆抗病品种S3的抗病基因奠定了基础.
To probe into the genetic resistant law to bacterial wilt (BW) in eggplant and quicken the breeding of resistance to BW, the genetic studies on resistance to BW is carried out. Observation in resistance to BW of 064(Beijing six-leaf eggplant),S3( a famous highly resistant half-cultivated species S3 of Malaysia) and 064譙3 F2 populations on the basis of two different methods of artificial inoculation on seedling in greenhouse shows that the method of root-cut inoculation is better than that of leaf-probe and the resistance gene of S3 is controlled by a single dominant gene.
