Resumo: In the final steps of a breeding program, it is necessary to evaluate several traits, which makes it difficult to select the superior genotypes. This study aimed to compare nonlinear indexes in the selection of superior soybean inbred lines obtained by recurrent selection. The experiment was carried out in Londrina, Paraná State, Brazil. During the 2010/11 and 2011/12 seasons, 67 soybean inbred lines and two commercial controls (BMX Potência RR and NK 7059 RR) were evaluated. The experimental design was a randomized complete block with three replicates. The evaluated traits were: days to maturity, agronomic value, lodging, first pod insertion height, and grain yield. A combined analysis of variance for seasons was performed and the sum of ranks index, ideotype distance index, and cultivars selection index were applied. All traits were significant for the genotypic source of variation and showed complex genotype × environment interactions. The selection indexes were consistent with each other. The ideotype and cultivar selection index showed higher concordance on indication of 15 superior inbred lines with a coefficient of coincidence of 80%. The inbred lines SR-03, SR-12, SR-22, SR-41, SR-49, SR-55, SR-61, and SR-62 were indicated for all indexes and are therefore considered superior to other inbred lines.

O presente trabalho teve como objetivo comparar índices não lineares na seleção de linhagens superiores de soja, obtidas por seleção recorrente. Os experimentos foram conduzidos em Londrina, Paraná, Brasil. Durante as safras 2010/11 e 2011/12 foram avaliados sessenta e sete linhagens de soja e duas testemunhas comerciais ((BMX Potência RR e NK 7059 RR). O delineamento experimental adotado foi em blocos completos ao acaso, com três repetições. As características avaliadas foram: dias para maturação, valor agronômico, acamamento, inserção da primeira vagem e produtividade de grãos. Realizou-se a análise de variância conjunta para anos agrícolas e empregaram-se os índices de soma de ranks, de distância ao ideótipo e de seleção de cultivares. Todas características para a fonte de variação genótipo foram significativas e apresentaram predomínio da interação complexa na interação genótipo x ambiente. Os índices de seleção se mostraram concordantes entre si. O índice de distância ao ideótipo e o índice de seleção de cultivar apresentaram maior concordância na indicação das 15 melhores linhagens com coeficiente de coincidência de 80%. As linhagens SR-03, SR-12, SR-22, SR-41, SR-49, SR-55, SR-61 e SR-62 foram indicadas em todos os índices e, portanto, consideradas superiores às demais.UEL2019-07-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3113510.5433/1679-0359.2019v40n5p1761Semina: Ciências Agrárias; Vol. 40 No. 5 (2019); 1761-1774Semina: Ciências Agrárias; v. 40 n. 5 (2019); 1761-17741679-03591676-546Xreponame:Semina.
