Resumo: | The objective of this work was to determine the inheritance of resistance by antixenosis in tomato plants (Lycopersicon esculentum) to tomato leafminer [Tuta absoluta (Lepidoptera: Gelechiidae)]. Evaluations were performed for tomato plants of the generations P1, P2, F1, F2, RC1 and RC2. The measured characteristic in the parents, BGH-1497 (P2 male) and 'Santa Clara' (P1 female), and in the F1, F2, RC1 and RC2 generations was the number of eggs per plant. This number was converted to the oviposition nonpreference index. The inheritance of antixenosis resistance of genotype BGH-1497 is ruled by a gene of greater effect and polygenes in epistatic interactions, with a phenotypic proportion of 13:3 between susceptible and resistant genotypes, respectively. |

As avaliações foram realizadas em plantas de tomate das gerações P1, P2, F1, F2, RC1 e RC2. A característica medida nos pais, BGH-1497 (masculino P2) e 'Santa Clara' (feminino P1), e nas gerações F1, F2, RC1 e RC2 foi o número de ovos por planta. Este número foi transformado em índice de não preferência por oviposição. A herança da resistência por antixenose do genótipo BGH-1497 é governada por um gene de efeito maior e poligenes em interações epistáticas, com uma proporção fenotípica de 13:3 entre genótipos suscetíveis e resistentes, respectivamente.Termo para indexação: Lycopersicon esculentum, Tuta absoluta, recursos genéticos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPEMIG, CNPqAntônio, Adilson de Castroda Silva, Derly José HenriquesPicanço, Marcelo CoutinhoSantos, Nerilson TerraFernandes, Maria Elisa de Sena2011-03-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/8581Pesquisa Agropecuaria Brasileira; v.46, n.1, jan. 2011; 74-80Pesquisa Agropecuária Brasileira; v.46, n.1, jan. 2011; 74-801678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/8581/6185https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8581/4308https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8581/4309https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8581/4310info:eu-repo/semantics/openAccess2014-05-15T19:31:27Zoai:ojs.seer.sct.embrapa.br:article/8581Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-05-15T19:31:27Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
