Estratégias de modelagem na análise de experimentos em delineamento de blocos aumentados em testes clonais de <i>Eucalyptus </i>spp.

Abstract: http://dx.doi.org/10.5902/1980509810546O presente trabalho foi realizado com o objetivo de comparar estratégias de análises de experimentos considerando um grande número de clones e um número reduzido de mudas a serem avaliadas. 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 qua… Show more

“…In the original augmented block design, the environmental variance was completely estimated based on the controls, because the regular genotypes were nonreplicated in the trial. Note that the use of this design is common in initial stages of breeding cycles, primarily because of the high number of genotypes and restricted resources (Peternelli, Souza, Barbosa, & Carvalho, 2009;Prado et al, 2013). However, this design might result in selective gains, and the accuracy might be improved with the use of spatial analysis and intereffect recovery (Silva Filho, 2013;Rodriguez-Álvarez, Boer, van Eeuwijk, & Eilers, 2018).…”
