Resumo: | Brazilian breeding programs usually aim at finding genotypes with early cycle and high grain yield. Thus, this study aimed to select early soybean lines with high grain yield for the Cerrado region. The experiment was carried out in the 2017-2018 season, in the Universidade Federal de Mato Grosso do Sul, Campus Chapadão do Sul, and consisted of an augmented blocks design, using 196 lines and ten controls, with five replications for each control. The experiment evaluated the traits plant height, number of days to flowering, and grain yield. After verifying the genetic variability for all traits, two selection methods were evaluated, the direct selection in each trait and the simultaneous selection (to decrease plant height and number of days to flowering and increase grain yield, using the Mulamba and Mock index). The latter considered two scenarios were when establishing the economic weight: the coefficient of genotypic variation (CVg) and arbitrary weights. Direct selection on the variables had unsatisfactory results. The Mulamba and Mock revealed unsatisfactory results when using CVg as the economic weight and satisfactory results when using arbitrary weights. |

Por lo tanto, este estudio tuvo como objetivo seleccionar líneas de soja precoces con alto rendimiento de granos para la región de Cerrado. El experimento se llevó a cabo en la temporada 2017-2018, en la Universidade Federal de Mato Grosso do Sul, Campus Chapadão do Sul, y consistió en un diseño de bloques aumentados, utilizando 196 líneas y diez controles, con cinco réplicas para cada control. El experimento evaluó los caracteres altura de la planta, número de días para la floración y rendimiento de granos. Después de verificar la variabilidad genética de todos los caracteres, se evaluaron dos métodos de selección, la selección directa en cada carácter y la selección simultánea (para reducir la altura de la planta y número de días para la floración y aumentar el rendimiento de los granos, utilizando el índice de Mulamba y Mock). Estos últimos consideraron dos escenarios a la hora de establecer el peso económico: el coeficiente de variación genotípica (CVg) y los pesos arbitrarios. La selección directa sobre las variables tuvo resultados insatisfactorios. El índice de Mulamba y el Mock revelaron resultados insatisfactorios al utilizar el CVg como peso económico y resultados satisfactorios al utilizar pesos arbitrarios.Os programas de melhoramento de soja brasileiros em sua maioria visam a obtenção de genótipos com ciclo precoce e alto rendimento de grãos. Assim, este estudo objetivou selecionar linhagens de soja precoces com alta produtividade para a região do Cerrado brasileiro. O experimento foi conduzido na safra 2017/2018 na Universidade Federal de Mato Grosso do Sul, Campus Chapadão do Sul, e consistiu de um delineamento de blocos aumentados usando 196 linhagens e dez controles, com cinco repetições para cada controle. Os caracteres avaliados foram altura de plantas, número de dias para o florescimento e produtividade de grãos. Após constatar a presença de variabilidade genética para todos os caracteres, avaliaram-se dois métodos de seleção: a seleção direta em cada caráter e a seleção simultânea (para reduzir a altura e o número de dias para o florescimento e aumentar a produtividade de grãos, usando o índice de Mulamba e Mock). Este último considerou dois cenários para estabelecer o peso econômico: o coeficiente de variação genotípico (CVg) e pesos arbitrários.
