Resumo: Inbreeding can potentially be used for the development of inbred lines containing alleles of interest, but the genetic causes that control inbreeding depression are not completely known, and there are few studies found in the literature. The present study aimed to obtain estimates of inbreeding depression for eight traits in seven tropical maize populations, analyze the effects of inbreeding over generations and environments, and predict the behavior of inbred lines in future generation S? through linear regression methods. It was found that regardless of the base population used, prediction values could vary when the model was based on only 2 generations of inbreeding due to the environmental component. The influence of the environment in this type of study could be reduced when considering 3 generations of inbreeding, allowing greater precision in predicting the phenotypes of inbred lines. The use of linear regression was effective for inbred line prediction for the different agronomic traits evaluated. The use of 3 levels of inbreeding minimizes the effects of the environmental component in inbred line prediction for grain yield. GO-S was the most promising population for inbred line extraction.

O presente estudo objetivou obter estimativas de depressão por endogamia para oito variáveis em sete populações de milho tropical, analisar o comportamento dos efeitos da endogamia sobre gerações e ambientes e prever o comportamento das linhagens na geração S?, por meio de métodos de regressão linear. Independentemente da população base utilizada, os valores de predição podem ser diferentes quando se consideram apenas dois níveis de endogamia, devido ao componente ambiental. A influência do ambiente neste tipo de estudo pode ser reduzida quando se consideram três níveis de endogamia, refletindo em maior precisão na predição das linhagens. O uso de regressão linear foi efetivo na predição de linhagens para as diferentes características agronômicas avaliadas. O uso de três níveis de endogamia minimiza os efeitos da componente ambiental na predição de linhagens puras para produtividade de grãos. GO-S foi a população mais promissora para a extração de linhagens.UEL2017-10-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2846410.5433/1679-0359.2017v38n5p2981Semina: Ciências Agrárias; Vol. 38 No. 5 (2017); 2981-2994Semina: Ciências Agrárias; v. 38 n. 5 (2017); 2981-29941679-03591676-546Xreponame:Semina.
