Resumo: This study was undertaken to test various repeatability coefficient estimation procedures, as well as to determine the adequate number of minitest of production in the selection of seedlings in rubber tree nursery. Three minitests were run on open-pollinated progeny seedlings of the RRIM 600 clones and the coefficient of repeatability estimated by using both the analysis of variance and principal components techniques, described by Mansour and co-workers. The equation that relates all three minitests of production explained about 87% of the existing variations among test. Since no marked differences among tests procedures were found in the estimation of the coefficient of repeatability, the ANOVA technique is recommended, due to its simplicity.

Foram utilizados três ministestes em plântulas oriundas de polinização aberta do clone RRIM 600 e estimados os coeficientes de repetibilidade, considerando os métodos da análise de variância e componentes principais, segundo metodologia apresentada por Mansour et al. (1981). A equação que relaciona os três minitestes de produção explicou cerca de 87% da variação existente entre os testes. Não foram detectadas grandes diferenças nas estimativas do coeficiente de repetibilidade entre os processos testados, optando-se, assim, pelo ANOVA, por ser de mais fácil utilização.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraVasconcellos, Maria Elizabeth da CostaGonçalves, Paulo de SouzaPaiva, João Rodrigues deValois, Afonso Celso Candeira2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15206Pesquisa Agropecuaria Brasileira; v.20, n.4, abr. 1985; 433-437Pesquisa Agropecuária Brasileira; v.20, n.4, abr. 1985; 433-4371678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15206/9034info:eu-repo/semantics/openAccess2014-04-17T11:50:40Zoai:ojs.seer.sct.embrapa.br:article/15206Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T11:50:40Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
