Resumo: | Knowledge of genetic diversity is of great importance to the contribution of plant breeding, as it helps plant breeders to better selecting parents for establishment of segregating populations. This knowledge is especially important to crops that presents a narrow genetic base as soybean. The objective of this work was to assess agronomic performance and genetic diversity of lines and soybean cultivars, in order to find those ones with potential to be used as parents in breeding programs. Experiment was carried out during 2015/2016 season in the Federal University of Uberlândia farm known as Capim Branco. A randomized complete block designed was applied in order to assess twenty-three morpho-agronomic features on twenty-four soybean genotypes. Significant genetic variability for all agronomic traits was found. Genotypes UFU B7, UFU B14, UFU B16, Msoy 6101 and UFUS 7910 were set as early maturity soybean, with life cycle duration ranging from 107.3 to 111 days. Genotypes UFU B1, UFU B3, UFU B8 and UFU B16 presented productivity values higher than national average of 2.870 kg ha-1. Genotypes were clustered by UPGMA, Tocher and canonical variables methods. Both UPGMA and Tocher methods formed four groups. NDF was the major contributor to genetic diversity. Hybridizations between UFU B3, UFU B8, UFU B16 genotypes with UFU B1 genotype might be promising for establishment of segregating populations shown superior genetic variability. Under these circumstances, it was concluded that agronomic features assessed were useful on detection of parents with potential to UFU's soybean breeding program. |

O objetivo do trabalho foi avaliar o desempenho agronômico e a diversidade genética de linhagens e cultivares de soja, com potencial de serem utilizados como genitores em programas de melhoramento genético. O experimento foi conduzido em uma área experimental localizada na Fazenda Capim Branco pertencente à Universidade Federal de Uberlândia na safra de 2015/2016. Foram avaliados 24 genótipos de soja, em delineamento de blocos completos casualizados, nos quais foram avaliados 23 caracteres morfo-agronômicos. Foi verificada variabilidade genética para todos os caracteres agronômicos. Os genótipos UFU B7, UFU B14, UFU B16, Msoy 6101 e UFUS 7910 foram classificados como genótipos de ciclo precoce, com duração variando de 107,3 a 111 dias. Os genótipos UFU B1, UFU B3, UFU B8 e UFU B16 apresentaram produtividade elevadas em relação aos demais com valores superiores à média nacional, que é de 2.870 kg ha-1. Os genótipos foram agrupados pelos métodos UPGMA, Tocher e variáveis canônicas. Pelos métodos UPGMA e Tocher foram formados quatro grupos distintos. O NDF foi o caractere que mais contribuiu com a diversidade genética. Hibridações dos genótipos UFU B3, UFU B8 e UFU B16 com o genótipo UFU B1 são promissoras para obtenção de populações segregantes com variabilidade genética superior. Desse modo concluiu-se que o uso de caracteres agronômicos permitiu detectar genitores potenciais para o programa de melhoramento de soja da UFU.
