Resumo: One of the biggest challenges for breeders in large companies, especially those that work with perennial plants, is to identify clones to be recommended, aiming at future commercial plantations and having information from the past, whose environmental conditions are unpredictable. In this condition, breeders seek to study strategies that can mitigate the effects of interaction between clones x environments (GA) at the time of their recommendation for forest exploitation. Given the above, the objective of this work was to study the interaction using compounds in relation to their respective monoclones; to verify if the compound formed from experiments with monoclones (MC) or Single Tree Plot (STP or clonal composites -CC) has different behavior in relation to the interaction; and to verify whether the possibility of determining the ideal number of clones to constitute the compound in the context of mitigating the interaction. Data from 60 clones provided by Suzano S/A were used. The experiments were conducted in six environments involving four states in Brazil. In each environment, the clones were evaluated simultaneously and continuously, in the designs of Single Tree Plot, with 30 replications, and DBC (MC plots with four rows of seven plants, and the ten central plants were evaluated, with three replications). The IMA data (m³.ha-¹.year-¹) in monoclone and in composites, at the age of three, were subjected to analysis of variance by environment and, subsequently, in joint analysis. Two research strategies were used. The first, from the clones with the best performance in MC or CC. The second by simulation, taking the clones entirely at random. Some methodologies were used to assess adaptability, stability, as well as recommendation risk estimates. It was found that the way to identify the clones to constitute the CC does not depend on whether they come from STP or MC experiments; the use of clonal compound proved to be more efficient than that of monoclones to mitigate the GA interaction. In many situations, the contribution of the clonal composites to the interaction was significant. However, associated with high productivity, which indicates that clonal compounds took better advantage of differences in environmental stimuli than most monoclones; the risk estimates for recommending clonal compounds were in most cases lower than for different monoclones; and the clonal composites with ten clones proved to be very effective in mitigating the interaction.

Nessa condição, os melhoristas buscam estudar estratégias que possam atenuar os efeitos da interação clones x ambientes (GA) no momento da recomendação dos mesmos para a exploração florestal. Diante do exposto, o objetivo desse trabalho foi estudar a interação utilizando compostos em relação aos seus respectivos monoclones; verificar se o composto formado a partir de experimentos com monoclones (MC) ou de Single Tree Plot (STP ou composto clonal -CC) tem comportamento diferente em relação a interação, e verificar se é possível determinar o número ideal de clones para constituir o composto no contexto de mitigação da interação. Foram utilizados dados de 60 clones cedidos pela empresa Suzano S/A. Os experimentos foram conduzidos em seis ambientes envolvendo quatro estados do Brasil. Em cada ambiente os clones foram avaliados de forma simultânea e contígua, nos delineamentos de Single Tree Plot, com 30 repetições, e DBC (parcelas de MC com quatro linhas de sete plantas, e avaliadas as dez plantas centrais, com três repetições). Os dados de IMA (m³.ha-¹.ano-¹) em monoclone e em composto, aos três anos, foram submetidos a análise de variância por ambiente e, posteriormente, a análise conjunta. Foram utilizadas duas estratégias para a pesquisa. A primeira, a partir dos clones com melhor performance em MC ou em CC, e a segunda por simulação, tomando os clones inteiramente ao acaso. Foram utilizadas algumas metodologias para avaliar a adaptabilidade, estabilidade, bem como estimativas de risco de recomendação. Constatou-se que o modo de identificar os clones para constituir o CC independe se oriundos de experimentos de STP ou MC; o emprego de composto clonal mostrou-se mais eficiente que de monoclones para mitigar a interação GA; em muitas situações a contribuição do composto clonal para a interação foi expressiva, contudo associado a alta produtividade indicando que os compostos clonais aproveitaram melhor as diferenças nos estímulos ambientais que a maioria dos monoclones; as estimativas de risco na recomendação dos compostos clonais foram, na maioria dos situações, inferior à dos diferentes monoclones; e o composto clonal com dez clones mostrou-se bem efetivo em mitigar a interação.Universidade Federal de LavrasPrograma de Pós-Graduação em Genética e Melhoramento de PlantasUFLAbrasilDepartamento de BiologiaRamalho, Magno Antonio PattoNovaes, EvandroRamalho, Magno Antonio PattoGonçalves, Flávia Maria AvelarLima, José LuisOliveira, Ana Flávia Cunha Fernandes de2021-01-20T17:51:45Z2021-01-20T17:51:45Z2021-01-202020-10-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfOLIVEIRA, A.
