Sources of curly top virus resistance in Capsicum

摘要

During a natural field epidemic of curly top virus, accessions within five species of Capsicum were evaluated for resistance. Accessions were considered resistant if 0 % to 25 % of the individual plants were devoid of curly top virus symptoms. Resistance was found in three accessions each of C. annuum L. and C. frutescens L. and one accession each of C. chacoense Hunt. and C. chinense Jacq. The resistant C. annuum accessions were 'Burpee Chiltepin','NuMex Bailey Piquin', and 'NuMex Twilight', while the C. fructescens resistant accessions were USDA-Grif 9322 from Costa Rica, PI 241675 from Ecuador and 'Tabasco'. The resistant C. chacoense accession was PI 273419 from Argentina and the C. chinense resistant accession was USDA-Grif 9303 from Colombia.
