Resumo: In Brazil, the improvement of papaya agribusiness is correlated to the estimation of genetic parameters and evaluation of agronomic descriptors; thus enabling less favourable areas for the development and implementation of papaya crops. Therefore, the current study aimed to evaluate quantitative descriptors and to estimate genetic parameters in genotypes of papaya grown under subtropical climate in the state of São Paulo. The experimental design was randomized in block. The experimental units were grouped into seven blocks of five plants each and three treatments, which consisted of three different varieties: Sunrise Solo, Tainung nº1 and local. The psychochemical properties were analysed for plant height; intersection height of first fruits; stem diameter; male, female and hermaphroditic flower percentage; fruit number per plant; production; yield; normal fruits percentage, carpeloid and pentandric fruits; pulp matter; pulp length; pulp diameter; pulp shape; pulp cavity; pulp thickness; peel performance; pulp performance; seeds performance; seeds number; soluble solids; pH; titratable acidity; ratio; technological index; ascorbic acid and reducing sugars. Furthermore, most agronomic descriptors showed high heritability; besides that, the varieties Sunrise Solo and Tainung nº1 performed the best results in Botucatu.

Frente ao exposto, objetivou-se com este trabalho avaliar descritores quantitativos e estimar parâmetros genéticos em genótipos de mamoeiro, cultivados em clima subtropical do estado de São Paulo. O delineamento experimental foi em blocos casualizados, com três tratamentos (variedade Sunrise Solo, híbrido Tainung nº1 e variedade local) e sete blocos, utilizando cinco plantas por parcela experimental. Foram mensuradas as seguintes caraterísticas: altura das plantas e da interseção dos primeiros frutos; diâmetro do caule; porcentagens de plantas masculinas, femininas e hermafroditas; número de frutos por planta; produção; produtividade; porcentagem de frutos normais, carpelóides e pentândricos; massa, comprimento, diâmetro, formato, diâmetro da cavidade interna e espessura da polpa dos frutos; rendimento de casca, de polpa e de sementes; número de sementes; sólidos solúveis; pH; acidez titulável; ratio; índice tecnológico; ácido ascórbico e açúcares redutores. Foi possível inferir com o estudo que há alta herdabilidade quanto à maioria dos descritores agronômicos avaliados e que os bons resultados para a variedade Sunrise Solo e o híbrido Tainung nº 1, possibilitam a indicação desses genótipos para cultivo, na região de Botucatu – SP.EDUFU2018-08-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3716410.14393/BJ-v34n1a2018-37164Bioscience Journal ; Vol. 34 No. 4 (2018): July/Aug.; 943-951Bioscience Journal ; v. 34 n. 4 (2018): July/Aug.; 943-9511981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/37164/22654Brazil; ContemporaryCopyright (c) 2018 Marcelo de Souza Silva, Sarita Leonel, Jackson Mirellys Azevêdo Souza, Joyce Helena Modesto, Rafael Bibiano Ferreira, Ana Carolina Batista Bolfarinehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Marcelo de SouzaLeonel, SaritaSouza, Jackson Mirellys AzevêdoModesto, Joyce HelenaFerreira, Rafael BibianoBolfarine, Ana Carolina Batista2022-02-14T12:00:46Zoai:ojs.www.seer.ufu.br:article/37164Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-14T12:00:46Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
