Resumo: | Plants of five tomato accessions (Lycopersicon esculentum Mill.) derived from diallel crossing, carrying modifier genes for normal fruit ripening and their F1 hybrids, except reciprocals, were evaluated. The pleiotropic effect of ‘stolid’ mutant and the nature and magnitude of genetic effects involved in the determination of those traits are provided. Although ‘stolid’ mutant increased shelf life, fruit firmness and the levels of carotenoid pigments, soluble solids contents decreased. Excepting fruit pH, all traits followed the additive-dominant model with additive genetic effects. Dominance deviations were also important, with the exception of fruit firmness. Additive genetic effects were more important for shelf life and titratable acidity and there was no predominance of any other particular genetic effect for remaining characteristics. Recessive genes were very important to increase shelf life and fruit firmness, while dominant genes increased the level of soluble solids and titratable acidity. Regression analysis of Wi on Vi, showed that cv. Santa Clara and ‘stolid’ mutant were divergent in shelf life, firmness and soluble solids of fruits. Selection can only be efficient for shelf life. Cross P1 (‘stolid’ mutant) with P5 (BGH-6913 - nor) has been shown to favour an increase of post-harvest conservation |

Os resultados evidenciaram que o mutante ‘firme’ promove aumento da vida de prateleira, firmeza e os níveis de pigmentos carotenóides, e reduz o teor de sólidos solúveis. Com exceção do caráter pH de frutos vermelhos, todos os caracteres seguiram o modelo aditivo-dominante, sendo os efeitos gênicos aditivos envolvidos no controle de todos os caracteres. Os desvios de dominância também foram importantes, exceto para o caráter firmeza de frutos. Nos caracteres vida de prateleira e acidez titulável os efeitos gênicos aditivos foram mais importantes, enquanto nos demais não houve predominância de particular efeito gênico. Constatou-se ainda maior importância de genes recessivos no aumento das expressões da vida de prateleira e firmeza de frutos, e dos genes dominantes, no aumento do teor de sólidos solúveis e da acidez titulável. Pela análise de regressão Wi em Vi, o cv. Santa-clara e o mutante ‘firme’ apresentam comportamento discrepante para os caracteres vida de prateleira, firmeza de frutos e teor de sólidos solúveis de frutos vermelhos. No entanto, a seleção pode ser eficiente apenas quanto a vida de prateleira, sendo que a combinação de P1 (mutante ‘firme’) com P5 (BGH-6913 - nor) pode promover aumento do período de conservação pós-colheitaUniversidade Estadual de Maringá2008-05-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/281310.4025/actasciagron.v22i0.2813Acta Scientiarum.
