Resumo: | The objective of this work was to compare analyses of experiment strategies when there is a large number of clones and a reduced number of seedlings to be evaluated. Data from girth at breast height of two seasons of evaluation, 30 and 90 months, from a clonal test of Eucalyptus were analyzed in three locations. The experiments were carried out in the augmented block design with 400 regular clones distributed in 20 blocks and with four common clones (controls). Each plot consisted of five plants spaced 3 x 3 meters. The individual statistic analyses were carried out by season and local, a combined one by local at each season and a combined one involving the three locals and the two seasons. Each analysis was carried out according to two models: augmented design (AD) and one way classification (OWC). The variance components, the heritability, the Speaman’s rank correlation and the coincidence indexes in the clone selection at the two models were estimated. It was found that the augmented block design and the one way classification provide similar results in eucalypt clone evaluation. The coincidence indexes between the two models in the clone selection, in general, were high, showing values of 100% in the local combined analyses at 90 months. The Spearman’s rank correlation showed estimates in accordance with the coincidence indexes. It was also checked that the clones by seasons interaction was expressive and the coincidence indexes in clones selection at 30 months with selection at 90 months in the combined by local analyses were from 42% in the OWC and 47% in AD, when a selection intensity of 5% was applied. |

Foram analisados dados da circunferência a altura do peito de duas épocas de avaliação, aos 30 e 90 meses, de um teste clonal de eucalipto em três locais. Os experimentos foram conduzidos no delineamento de blocos aumentados, com 400 clones regulares distribuídos em 20 blocos e com quatro clones comuns (testemunhas). A parcela foi constituída de cinco plantas no espaçamento 3 x 3 metros. Foram realizadas as análises estatísticas individuais por local e época, a conjunta de locais por época e a conjunta envolvendo os três locais e as duas épocas. Cada uma das análises foi realizada de acordo com dois modelos: blocos aumentados (DBA) e entre e dentro (ED). Foram estimados os componentes de variância, as herdabilidades, a correlação de Spearman na classificação dos clones e os índices de coincidência na seleção dos clones. Constatou-se que as análises em DBA e as análises ED fornecem resultados semelhantes na avaliação de clones de eucalipto. Os índices de coincidência entre os dois modelos na seleção dos clones, de maneira geral, foram altos, apresentando valores de 100% nas análises conjuntas de locais aos 90 meses. As estimativas das correlações de Spearman foram concordantes com os índices de coincidência. Verificou-se, também, que a interação clones x épocas foi expressiva e que os índices de coincidência na seleção dos clones aos 30 meses e aos 90 meses, nas análises conjuntas de locais, foram da ordem de 42% no ED e 47% no DBA, quando considerada uma intensidade de seleção de 5%.Universidade Federal de Santa Maria2019-11-14T16:03:35Z2019-11-14T16:03:35Z2013-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPRADO, P.
