Resumo: The objective of this work was to compare fruit weight and length of cycle, among cultivars of plum and peach, besides estimating the repeatability and determination coefficients and the number of measurements, for a safe prediction of these characteristics, and to compare different methods to estimate the repeatability. The traits were evaluated in 5 productive cycle for 9 plum cultivars (Prunus salicina) and 33 peach cultivars (Prunus persica), in a completely randomized design. The repeatability coefficient was estimated by methods of analysis of variance, principal components and structural analysis. The greates fruit weight was observed for Harry Pickstone and Pluma 7 plum cultivars and for Santa Aurea peach cultivar. The shortest lenght of cycle occurred in America, Irati and Methley plum cultivars and in Granada peach cultivar. The repeatability and determination coefficients were high for both traits in plum and in peach trees. There were no differences in the repeatability coefficient estimation among the methods used. One to three measurements of fruit weight and one and two measurements of length of cycle are necessary for obtaining the real genotypic values of plum and peach cultivars, respectively, with a determination coefficient of 90%.

O coeficiente de repetibilidade foi estimado pelos métodos de análise de variância, componentes principais e análise estrutural. Foi observado o maior peso de fruto nas cultivares de ameixeira Harry Pickstone e Pluma 7 e na cultivar de pessegueiro Santa Áurea. A menor duração do ciclo ocorreu nas cultivares de ameixeira América, Irati e Methley e na cultivar de pessegueiro Granada. Os coeficientes de repetibilidade e de determinação foram altos para ambos os caracteres em ameixeira e pessegueiro. Não houve diferenças no coeficiente de repetibilidade entre os métodos utilizados. São necessárias de uma a três medições de peso de fruto, e de uma a duas medições da duração do ciclo, para obtenção dos valores genotípicos reais das cultivares de ameixeira e pessegueiro, respectivamente, com coeficiente de determinação de 90%.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraDanner, Moeses AndrigoRaseira, Maria do Carmo BassolsSasso, Simone Aparecida ZoletCitadin, IdemirScariot, Silvia2011-01-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/8332Pesquisa Agropecuaria Brasileira; v.45, n.8, ago. 2010; 872-878Pesquisa Agropecuária Brasileira; v.45, n.8, ago. 2010; 872-8781678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/8332/6084https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8332/4003info:eu-repo/semantics/openAccess2014-11-10T16:14:57Zoai:ojs.seer.sct.embrapa.br:article/8332Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-10T16:14:57Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
