不同抗病基因型番茄对番茄黄化曲叶病毒的抗病性鉴定

对抗病基因进行抗性评价是番茄抗病育种的重要环节。选用6种抗病番茄材料和2种感病番茄材料,利用携带番茄黄化曲叶病毒（Tomato yellow leaf curl virus,TYLCV）的烟粉虱对所选番茄材料幼苗接种病毒,统计分析各材料的病情指数、病株率和带毒率,鉴定不同基因型番茄材料的抗性水平。结果表明,所有接种材料中均可以检测到携带TYLCV,其中含有Ty-2和Ty-5基因的番茄材料对江苏地区TYLCV病毒种类抗性较好,Ty-3次之,Ty-1抗性相对较弱,Ty-3a在樱桃番茄中抗性强于大果型番茄。本试验为抗病育种过程中对抗病基因的选择提供了一定的参考依据。...

To assess resistant levels of genes is an important part of the breeding tomato for disease resistance,six resistant tomato lines and two susceptible tomato lines by whiteflies were infected to tomato yellow leaf curl virus（TYLCV）,and their disease index,disease incidence and poisoned rate to assess resistant levels of different resistance genes were counted and analyzed.The results showed that all infected tomatoes carried TYLCV by detection,of which the materials containing Ty-2 and Ty-5 performed superior resistance to TYLCV of Jiangsu,the second one was Ty-3,and Ty-1 was relatively weak.The resistance of Ty-3a in cherry tomatoes was stronger than that in big fruit type tomatoes.This study provided a basis
