Abstract In this paper，a F2 population including 146 individuals were used for research，which were derived from CMV resistant pepper（Capsicumm annuum L.）inbred line‘perennial’and sensitive inbred line‘Qiemen’with good horticultural traits．Based on screening the SRAP and SSR primers and analyzing genotypes of the F2 population，a genetic linkage map of pepper was constructed．F3 population（4 380 individuals）which derived from F2 146 selfed individuals were used for inoculate CMV．Then 3 main QTLs were located in linkage group 1，4 and 7，respectively，which accounted for 12.7%，38.8% and 11.0% of the total resistance variance.
