Resumo: | An adequate experimental plan is necessary to get high quality data. Experimental plan ensures correct plot size and shape as well as adequate number of replications and samples. The objective of this work was to verify if maize genetic variability could interfere in the size of experimental plots and number of replications. Single (DAS 9560), double (AG 6018) and triple (AG 303) crosses and the open pollinated variety (Pampa) were evaluated. The experiment was carried out in a randomized complete block design with four replications. Plot samples comprised experimental plots with eight rows of 12 m with 96 basic units. Lessman & Atkins and Hatheway methods were used to estimate optimum plot size and replication number. The best plot size varied from 4.5 m2 (simple hybrid) to 7.2 m2 (double hybrid). Soil heterogeneity and genetic variability change plot size and number of replications requested. |

O objetivo deste trabalho foi avaliar a influência de diferentes bases genéticas de milho, híbrido simples (DAS 9560), duplo (AG 6018), triplo (AG 303) e variedade cultivada (Pampa), sobre a estimativa do tamanho de parcela experimental e do número de repetições. O delineamento experimental foi de blocos ao acaso com quatro repetições e amostragem nas parcelas. As parcelas experimentais foram constituídas por oito fileiras com 12 metros de comprimento, formando 96 unidades básicas. O tamanho de parcela e o número de repetições foram estimados por meio dos métodos de Lessman & Atkins e de Hatheway. O tamanho ótimo de parcela variou entre 4,5 m2 (híbrido simples) e 7,2 m2 (híbrido duplo). A heterogeneidade do solo e a variabilidade genética influenciam no tamanho ótimo de parcela e número de repetições necessárias.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMartin, Thomas NewtonStorck, LindolfoLúcio, Alessandro Dal'ColCarvalho, Melissa Pisaroglo deSantos, Paula Machado dos2005-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6918Pesquisa Agropecuaria Brasileira; v.40, n.1, jan. 2005; 35-40Pesquisa Agropecuária Brasileira; v.40, n.1, jan. 2005; 35-401678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6918/3966info:eu-repo/semantics/openAccess2014-09-23T17:43:58Zoai:ojs.seer.sct.embrapa.br:article/6918Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-23T17:43:58Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
