Resumo: | Psidium guajava L. (guava) is an important species that presents high genetic variability due to its mixed reproductive system, which is desired in breeding programs. Repeatability is an important tool for the selection of genotypes in pre-breeding studies. When genetic variability is present, the knowledge regarding the number of samples to be used in repeatability studies is indispensable. This study aims to determine the number of necessary measures while optimizing resources and maintaining the reliability of the results for the variables evaluated in P. guajava. The experiment was carried out with genotypes from three Brazilian States: Espírito Santo, São Paulo, and Minas Gerais, and a total of 79 P. guajava genotypes were collected. The following characteristics were evaluated: young leaf length and width; developed leaf length and width; fruit length; fruit diameter and fruit cavity diameter; and fruit weight and pulp weight. For the evaluated characteristics, deviance, permanent phenotypic and temporary environment variance, coefficients of repeatability and determination, accuracy and the number of estimated measurements required were determined. We established that the number of measurements required in repeatability analysis for a coefficient of repeatability with a reliability of 80% is four, for the measurements of developed leaf width, pulp weight, fruit diameter, and fruit cavity diameter. |

(goiaba) é uma espécie importante que apresenta alta variabilidade genética devido ao seu sistema reprodutivo misto, o que é desejado em programas de melhoramento. A repetibilidade é uma ferramenta importante para a seleção de genótipos em estudos de pré-melhoramento. Quando a variabilidade genética está presente, o conhecimento sobre o número de amostras a serem usadas em estudos de repetibilidade é indispensável. Este estudo tem como objetivo determinar o número de medidas necessárias, otimizando recursos e mantendo a confiabilidade dos resultados para as variáveis avaliadas em P. guajava. O experimento foi conduzido com genótipos de três estados brasileiros: Espírito Santo, São Paulo e Minas Gerais, e um total de 79 genótipos de P. guajava foram coletados. As seguintes características foram avaliadas: comprimento e largura das folhas jovens; comprimento e largura das folhas desenvolvidas; comprimento do fruto; diâmetro do fruto e diâmetro da cavidade do fruto; e peso do fruto e peso da polpa. Para as características avaliadas, foram determinados os desvios, a variância fenotípica permanente e temporária do ambiente, os coeficientes de repetibilidade e determinação, a precisão e o número estimado de medidas necessárias. Foi estabelecido que o número de medições necessárias na análise de repetibilidade para um coeficiente de repetibilidade com uma confiabilidade de 80% é igual a quatro, para as medidas de largura de folha desenvolvida, peso da polpa, diâmetro do fruto e diâmetro da cavidade do fruto.EDUFU2019-04-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4195310.14393/BJ-v35n2a20198-41953Bioscience Journal ; Vol. 35 No. 2 (2019): Mar./Apr.; 377-388Bioscience Journal ; v. 35 n. 2 (2019): Mar./Apr.; 377-3881981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/41953/25783Brazil; ContemporaryCopyright (c) 2019 José Henrique Soler Guilhen, Luina Ribeiro Noia, Carolina de Oliveira Bernardes, Wagner Bastos dos Santos Oliveira, Tiago de Souza Marçal, Marcia Flores da Silva Ferreira, Adésio Ferreirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGuilhen, José Henrique SolerNoia, Luina RibeiroBernardes, Carolina de OliveiraOliveira, Wagner Bastos dos SantosMarçal, Tiago de SouzaFerreira, Marcia Flores da SilvaFerreira, Adésio2022-02-02T04:49:12Zoai:ojs.www.seer.ufu.br:article/41953Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-02T04:49:12Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
