High Resolution Melting Analysis을 이용한 고추 유전자원의 Cucumber mosaic virus 저항성 평가

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. frutes...

Summary: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. 농업유전자원센터에 보존하고 있는 고추 유전자원 1,941점을 240H02sp6 SNP 마커를 이용하여 Cucumber mosaic virus 저항성 정도를 평가하였다. 1941점의 고추 유전자원에서 89점이 저항성, 162점이 이형접합성, 1270점이 이병성으로 분석되었다. 고추 종별로는 C. annuum은 총 839자원 중 38점이 저항성으로 나타났으며, C. baccatum은 277점 중 23%에 해당하는 자원만 분석이 되었고 분석된 자원 중 20점이 저항성을 나타났다. C. chinense는 21점이 저항성, C. frutescens는 8점이 저항성을 보였다. C. pubescens는 K157779 자원만 이병성을 나타내었으며, Capsicum sp. 자원들 중에는 저항성 자원이 없었다. 야생근연종인 C. chacoense는 15점이 분석되어 1점이 저항성, 4점이 이형접합성, 6점이 이병성을 보였고, C. galapagoense, C. tovarii는 각 한 점씩 분석되었고 모두 이병성으로 나타났다.
