Resumo: Thie objective of this work was to evaluate yield, quality and postharvest conservation of tomatoes, to compare the effects promoted by the alcobaça (norA), nonripening (nor) and ripening inhibitor (rin) alleles, in heterozygosis, singly or in double combinations on hybrid tomato fruits. Ten treatments were evaluated: seven experimental nearly isogenic hybrids of FloraDade x Tropic background or reciprocal with nor+/norA, rin+/rin, nor+/nor, nor/norA, nor+/norA rin+/rin and nor+/nor rin+/rin genotypes, and three commercial checks (FloraDade, Tropic and Carmen F1). Oppositely to the genotypes rin+/rin and nor+/nor, the genotype nor+/norA did not significantly extend the firmness of the fruits in postharvest. The double mutant genotypes norA/nor, nor+/norA rin+/rin and nor+/nor rin+/rin were efficient in delaying firmness loss and the evolution of fruits colouring; the effects of loci nor+/norA and rin+/rin, together, underwent significant deviations relatively to the sum of these loci effects, when acting singly, in the sense of enhancing those delays. Use of heterozygous hybrids in the double combinations among loci norA, nor and rin proved advantageous for providing firm fruits with a longer postharvest lifetime, as compared with the hybrids carrying these loci singly. The quality of double mutant fruits was not restricted by the delay in the evolution of red coloration.

Foram avaliados dez tratamentos: sete híbridos experimentais quase-isogênicos, com background FloraDade x Tropic de genótipos nor+/norA, rin+/rin, nor+/nor, nor/norA, nor+/norA rin+/rin e nor+/nor rin+/rin; e três testemunhas comerciais (Floradade, Tropic e Carmen F1). Contrariamente aos genótipos rin+/rin e nor+/nor, o genótipo nor+/norA não prolongou, significativamente, a firmeza dos frutos em pós-colheita. Os genótipos duplo-mutantes norA/nor, nor+/norA rin+/rin e nor+/nor rin+/rin foram eficientes em atrasar a perda de firmeza e a evolução da coloração dos frutos; os efeitos dos locos nor+/norA e rin+/rin, juntos, sofreram desvios significativos em relação à soma dos efeitos desses locos, quando atuaram separadamente, no sentido de intensificarem esses atrasos. O uso de híbridos heterozigotos, nas duplas combinações entre os locos norA, nor e rin, mostrou-se vantajoso por propiciar frutos firmes, com maior extensão da vida pós-colheita, em comparação com o uso dos híbridos portadores desses locos isoladamente. A qualidade dos frutos duplo-mutantes não foi limitada pelo atraso na evolução da coloração vermelha.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraJúnior, Alcides Militão dos SantosMaluf, Wilson RobertoFaria, Marcos Venturade Andrade Júnior, Valter Carvalhodo Nascimento, Ildon RodriguesBenites, Flávio Rodrigo GandolfiGomes, Luiz Antônio Augusto2005-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7085Pesquisa Agropecuaria Brasileira; v.40, n.12, dez. 2005; 1203-1210Pesquisa Agropecuária Brasileira; v.40, n.12, dez. 2005; 1203-12101678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7085/4133info:eu-repo/semantics/openAccess2014-09-19T16:19:13Zoai:ojs.seer.sct.embrapa.br:article/7085Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-19T16:19:13Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
