摘　　要：采用田间自然接种番茄黄花曲叶病毒(TYLCV)的鉴定方法,对来自番茄野生种类番茄茄Solanum.lycopersicoides LA2951的渐渗系(Introgression Line,IL)群体进行了筛选,发现类番茄茄LA2951对TYLCV的抗性受多个位点控制。通过分析不同IL的抗性,共鉴定出7个QTL,分别位于染色体1、3、4、5、6、7和12上,其中位于染色体1上的QTL有待于进一步确定。An introgression line（IL）population,which was derived from a wild relative Solanum lycopersicoides LA2951,was used to screen the involved loci for resistance to TYLCV by the natural inoculation. In total,7 QTLs conferring the resistance to TYLCV were identified after the analysis of different individuals of IL population,which were respectively located on chromosome 1,3,4,5,6, 7 and 12. Among them,QTL involved in chromosome 1 still need to be addressed further.
