| Abstract |
|
In this study, total number of 1941 Capsicum accessions conserved at RDA Genebank was evaluated for their response to Cucumber mosaic virus (CMV). These accessions were composed with 9 species originated from 89 countries, included 839 Capsicum annuum, 277 C. baccatum, 395 C. chinense, 343 C. frutescens, 49 C. pubescens, and other 38 wild pepper species (C. chacoense, C. galapagoense, etc.). Resistant to CMV was screened with the 240H02SP6 SNP marker related to the Cmr1 (Cucumber mosaic resistance 1). Eighty nine accessions of pepper germplasm were resistant to CMV based on the marker. One hundred sixty two accessions showed heterozygosity. One thousand two hundred seventy accessions were susceptible to CMV. Four hundred twenty accessions did not show distinction by 240H02SP6 marker. These 89 resistant pepper germplasm can be used in a pepper breeding program against CMV. |
