Resumo: In order to increase the yield of vegetables of agronomic interest, heterosis has been studied in view of the superiority of hybrids, if compared to genotypes obtained by free pollination. This study aimed to estimate the relative heterosis in watermelon hybrids, regarding the most important agronomic traits, in order to develop future cultivars. The genotypes ‘JNY’, ‘ORA’, ‘KOD’, ‘SOL’, ‘CHG’, ‘PEA’ and all hybrids among them were used, totaling 36 treatments. A randomized block design, with three replications and five-plant plots, was used. The genotypes ‘ORA’, ‘SOL’, ‘CHG’ and ‘PEA’ were promising for the development of watermelon hybrids with higher weight, whereas ‘JNY’ and ‘KOD’ provided combinations with lower fruit weight and smaller seeds, indicating their potential for the development of cultivars of the ‘ice box’ type. The hybrids ‘CHG x ORA’ and ‘ORA x CHG’ were promising to meet the market demand for larger fruits, while ‘KOD x JNY’ and ‘JNY x KOD’ could be targeted to the market of smaller fruits.

Objetivou-se estimar a heterose relativa em híbridos de melancia para os principais caracteres de interesse agronômico, visando ao desenvolvimento de futuras cultivares. Foram utilizados os genótipos ‘JNY’, ‘ORA’, ‘KOD’, ‘SOL’, ‘CHG’, ‘PEA’ e todos os híbridos possíveis entre eles, totalizando 36 tratamentos. Empregou-se o delineamento de blocos casualizados, com três repetições e parcelas com cinco plantas. Os genitores ‘ORA’, ‘SOL’, ‘CHG’ e ‘PEA’ apresentaram-se promissores para o desenvolvimento de híbridos de maior massa, enquanto ‘JNY’ e ‘KOD’ proporcionaram combinações com menor massa de fruto e sementes pequenas, indicando o seu potencial para o desenvolvimento de cultivares do tipo “mini”. Os híbridos ‘CHG x ORA’ e ‘ORA x CHG’ foram promissores para atender a demanda de mercado por frutos maiores, enquanto ‘KOD x JNY’ e ‘JNY x KOD’ podem ser destinados à comercialização de frutos menores.Escola de Agronomia - Universidade Federal de Goiás2018-07-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/51779Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 48, n. 2, Apr./Jun. 2018; 170-177Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 48, n. 2, abr./jun. 2018; 170-177Pesquisa Agropecuária Tropical; v. 48, n. 2, abr./jun. 2018; 170-1771983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/51779/25828Copyright (c) 2018 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessLima do Nascimento, Tiagode França Souza, Fláviode Cássia Souza Dias, Ritada Silva, Edson Ferreira2020-07-13T19:08:16Zoai:ojs.revistas.ufg.br:article/51779Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:20.062332Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
