| 摘 要： | 利用番茄抗病基因Tm-2a、I-2、Mi-1、Cf-9的分子标记辅助选择，聚合抗烟草花叶病、抗枯萎病、抗根结线虫和抗叶霉病4个基因于番茄育种材料中。室内苗期接种鉴定和田间观察，获得的含4个抗性基因的株系L11、L19、L46和L51对4种病害都达到了抗级（R）水平，且具有较好的农艺性状，可作为抗病育种亲本。

| Abstract: | The elite lines of L11，L19，L46 and L51 containing Tm-2a，I-2，Mi-1 and Cf-9 resistant genes were obtained in tomato with the aid of the molecular marker assisted selection. Seedling inoculation of these inbred lines confirmed higher disease resistant levels. The results of field trials also showed that the four selected disease resistance lines have better agricultural characteristics and may be used for tomato disease resistance breeding program in the future. |
