Abstract Totally 209 Capsicum germplasm were identified by molecular markers，which linked to pepper
bacterial resistant scab Bs2，Bs3 gene，root-knot nematode resistant Me1，Me3/Me4 gene，virus disease
resistant L4，Pvr4，Tsw gene，powdery mildew resistant PMR1 gene and epidemic disease resistant Phyto5.2
loci．The results showed that there were only one pepper germplasm carrying Bs2 gene；4 carrying Bs3 gene；
48 carrying Me1 gene with linked marker 16880-1-V2 fragment isozygoty loci and 12 with heterozygous loci；
and one carrying Me3/Me4 gene with linked marker fragment SCAR_B94；11 carrying homozygous disease
resistant material TMV L4/L4 genotype；1 carrying heterozygous disease resistant material L4/L0 genotype；30
carrying PVY Pvr4 resistant gene with linked marker CSO fragment isozygoty loci and 8 heterozygous loci；4
carrying Tsw resistance locus with linked marker SCAC568 fragment；3 carrying PMR1 gene with linked marker
ZL1_1826 fragment；and 38 carrying Phyto5.2 locus with linked marker OpD04.717 fragment．This study
has identified preliminarily the genotypes of 209 pepper germplasm resources and provided basis for selecting
disease resistant pepper materials．
