Summary: | The objective of this work was to assess the degree of resistance to the whitefly (Bemisia argentifolii) and to the two-spotted spider mite (Tetranychus urticae) of tomato hybrids resulting from crosses between high-zingiberene (ZGB) lines and high-acylsugar (AS) lines, as compared to their parental lines and to commercial vouchers. High-AS lines, high-ZGB lines, double heterozygous (ZGB+AS) hybrids, hybrids heterozygous for ZGB and hybrids heterozygous for AS were tested. The wild accessions PI 127826 and LA-716 were used as high-ZGB and high-AS vouchers, respectively, while the genotypes Debora Max and TOM-684 were used as vouchers for low ZGB and AS. The genotypes were submitted to resistance tests to the whitefly and repellency to the spider mite. Double heterozygous (ZGB+AS) hybrids were more resistant to whiteflies than the commercial vouchers, but less resistant than the high-ZGB or the high-AS lines. Double heterozygous (ZGB+AS) hybrids were more repellent to the spider mite than the commercial vouchers, and their repellency to mites was similar to that of high-ZGB or high-AS lines. There was no synergistic effect between ZGB and AS, for both resistance to the whitefly and repellency to the two-spotted spider mite, in the double heterozygous (ZGB+AS) genotypes. |

Foram avaliadas linhagens com altos teores de AA, linhagens com alto teor de ZGB, híbridos duplos heterozigotos ZGB+AA, híbridos heterozigotos para ZGB e híbridos heterozigotos para AA. Os acessos selvagens PI-127826 e LA-716 foram utilizados como testemunhas para alto teor de ZGB e AA, respectivamente, e os genótipos Débora Max e TOM-684 foram utilizados como testemunhas para baixo teor de ambos os aleloquímicos. Os genótipos foram submetidos ao teste de resistência à mosca-branca e ao teste de repelência ao ácaro. Os genótipos duplos heterozigotos apresentaram graus de resistência à mosca-branca superiores aos das testemunhas comerciais e inferiores aos das linhagens com alto ZGB ou com alto AA. Os genótipos duplos heterozigotos apresentaram maior repelência ao ácaro, em relação às testemunhas comerciais, e repelência semelhante à das linhagens com alto ZGB ou com alto AA. Não foi observado efeito sinérgico entre ZGB e AA nos genótipos duplos heterozigotos quanto à resistência à mosca-branca e repelência ao ácaro.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq, CAPES, FAPEMIG, MCT, UFLA, FUNDECC, FAEPESilva, Vanisse de FátimaMaluf, Wilson RobertoCardoso, Maria das GraçasNeto, Álvaro Carlos GonçalvesMaciel, Gabriel MascarenhasNízio, Daniela Aparecida CastroSilva, Vânia Aparecida2010-12-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/2088Pesquisa Agropecuaria Brasileira; v.44, n.10, out. 2009; 1262-1269Pesquisa Agropecuária Brasileira; v.44, n.10, out. 2009; 1262-12691678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/2088/5838https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/2088/1487https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/2088/1488https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/2088/1489info:eu-repo/semantics/openAccess2012-06-17T11:53:41Zoai:ojs.seer.sct.embrapa.br:article/2088Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:53:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
