摘要
利用已发表的与辣椒抗细菌性疮痂病Bs2、Bs3基因,抗根结线虫Me1、Me3/Me4基因,抗病毒病L4、Pvr4、Tsw基因,抗白粉病PMR1基因,抗疫病Phyto5.2位点连锁的分子标记,对209份辣椒种质进行分子标记检测。结果表明,209份辣椒种质中携带Bs2基因的种质1份、携带Bs3基因的种质4份;携带Me1基因连锁标记16880-1-V2片段的纯合位点种质48份、杂合位点种质12份,携带Me3/Me4基因连锁标记片段SCAR_B94的种质1份;携带抗TMV L4/L4基因型的纯合抗病材料11份,L4/L0基因型的杂合抗病材料1份;携带抗PVY Pvr4基因连锁标记CSO片段的纯合位点种质30份,杂合位点种质8份;携带抗TSWV Tsw位点连锁标记SCAC568片段的种质4份;携带PMR1基因连锁标记ZL1_1826片段的种质3份;携带Phyto5.2位点连锁标记OpD04.717片段的种质38份,初步明确了209份供试辣椒种质的抗性基因型,为辣椒抗病育种提供材料选择依据。
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.
