Mapping of QTLs Conferring the Resistance to Tomato Yellow Leaf Curl Virus(TYLCV)in Solanum lycopersicoides

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.
