Resumo: The objective of this work was to prospect for new sources of resistance to leprosis in the Citrus Germplasm Bank of Centro APTA Citros Sylvio Moreira, Instituto Agronômico, in Cordeirópolis, SP, Brazil. Plants obtained through seeds from 26 citrus accessions were mite-infected with Citrus leprosis virus (CiLV). Typical lesions started to appear in 11 genotypes (42.3% of the tested accessions) 21 days after inoculation. Fifteen species, among them Citrus pennivesiculata and C. celebica, behaved as highly resistant, while other genotypes, as C. keraji, were more susceptible than the standard C. sinensis. The data showed a wide variation in the response of Citrus spp. to leprosis, with a large number of resistant species, wich can be used as source of resistance to this disease, in breeding programs.

Foram utilizadas plantas obtidas por sementes de 26 acessos, infectadas com o vírus da leprose-dos-citros (Citrus leprosis virus – CiLV), por meio do seu vetor Brevipalpus phoenicis. O aparecimento de lesões, a partir de 21 dias após a inoculação, foi observado em 11 dos genótipos testados (42,3%). Quinze espécies, entre elas Citrus pennivesiculata e C. celebica, comportaram-se como altamente resistentes, enquanto outras, como C. keraji, foram mais suscetíveis que o padrão C. sinensis. Os dados mostraram grande variação de respostas de Citrus spp. à leprose, com elevado número de espécies resistentes, que podem ser utilizadas como fonte de resistência à doença em programas de melhoramento.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPESP e CNPqFreitas-Astúa, JulianaFadel, André LuizBastianel, MarinêsNovelli, Valdenice MoreiraAntonioli-Luizon, RenataMachado, Marcos Antônio2008-10-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/646Pesquisa Agropecuaria Brasileira; v.43, n.7, jul. 2008; 809-814Pesquisa Agropecuária Brasileira; v.43, n.7, jul. 2008; 809-8141678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/646/5460info:eu-repo/semantics/openAccess2014-07-02T17:21:59Zoai:ojs.seer.sct.embrapa.br:article/646Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-02T17:21:59Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
