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.
