Resumo: The objective of this work was to determine the repeatability coefficient of fruit quality characteristics of sweet orange (Citrus sinensis) and the minimum number of evaluations that can provide levels of prediction certainty of the true genotype value. Thirty nine genotypes of sweet orange, collected in nine municipalities of the state of Acre, Brazil, were evaluated in five crop cycles. A randomized complete block design was used, with three replicates. The following were evaluated: average fruit weight, juice yield, peel thickness, soluble solids (SS), total acidity (TA), SS/TA ratio, and technological index. To estimate the repeatability coefficients, the methods of analysis of variance, principal component analysis, and structural analysis were used. All evaluated characters showed variability, except for juice yield. The evaluated characters showed a cyclic pattern, which was best captured by the multivariate methodologies for estimating the repeatability coefficient. Fifteen evaluations are needed to determine, with 90% certainty, the characters peel thickness and soluble solids, and 11, 6, 3, 2, and 1 evaluations, respectively for average fruit weight, total acidity, technological index, juice yield, and SS/TA ratio, respectively.

Foram avaliados, em cinco safras, 39 genótipos de laranjeira‑doce, coletados em nove municípios do Estado do Acre. Utilizou-se o delineamento de blocos ao acaso, com três repetições. Foram avaliados: massa média de frutos, rendimento de suco, espessura de casca, sólidos solúveis (SS), acidez total (AT), relação SS/AT e índice tecnológico. Para a estimativa dos coeficientes de repetibilidade, foram utilizados os métodos da análise de variância, dos componentes principais e da análise estrutural. Todos os caracteres avaliados mostraram variabilidade, exceto o rendimento de suco. Os caracteres avaliados mostraram padrão cíclico, o que foi mais bem captado pelas metodologias multivariadas de estimativa do coeficiente de repetibilidade. São necessárias 15 avaliações para determinar, com 90% de certeza, os caracteres espessura de casca e sólidos solúveis, e 11, 6, 3, 2 e 1 avaliações, respectivamente para massa média de fruto, acidez total, índice tecnológico, rendimento de suco e relação SS/AT.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTesouro Nacional e CNPqNegreiros, Jacson Rondinelli da SilvaAndrade Neto, Romeu de CarvalhoMiqueloni, Daniela PopimLessa, Lauro Saraiva2014-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/18289Pesquisa Agropecuaria Brasileira; v.49, n.1, jan. 2014; 40-48Pesquisa Agropecuária Brasileira; v.49, n.1, jan. 2014; 40-481678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/18289/12499https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/18289/10843info:eu-repo/semantics/openAccess2014-04-04T16:14:26Zoai:ojs.seer.sct.embrapa.br:article/18289Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-04T16:14:26Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
