| description | In this work, the objective was to evaluate morphoagronomic traits, correlate and select elite genotypes of Stevia rebaudiana (Bert.) Hemsley with high productivity, and adapted to Brazilian Savanna conditions. A total of 230 genotypes were evaluated, from the Embrapa Cerrados Working Collection, from 2018 to 2019, with 24 evaluations, carried out in six cuts, with each cut representing a certain moment of generation of the response data of the analyzed genotypes. Four traits were analyzed: green biomass production (g), plant height (cm), tillering number and juvenile period of each individual. The means of the characteristics of each genotype were correlated according to Pearson's correlation coefficient. The Mulamba and Mock index was applied, with a selection intensity of 10%, to choose the superior genotypes. There are high positive correlations between juvenile period, height and green biomass production. The selected population were 23 superior genotypes, based on the application of rank sum resulting in high selection gains for the traits of interest. Finally, the selection of elite stevia genotypes with high production of green biomass, greater insensitivity to length of the daily light period, as well as taller plants, are essential for the continuity of the stevia breeding program on the Brazilian Savanna. |

En este trabajo, el objetivo fue evaluar las características morfoagronómicas, correlacionar y seleccionar genotipos étilite de Stevia rebaudiana (Bert.) Hemsley con alta productividad y adaptados a las condiciones de la Sabana Brasileña. Se realizaron 24 evaluaciones a 230 genotipos procedentes de la colección de trabajo de Embrapa Cerrados, de 2018 a 2019 en seis cortes, representando cada corte un determinado momento en la generación de datos de respuesta de los genotipos analizados. Se analizaron cuatro características: la producción de biomasa verde (g), la altura de la planta (cm), el número de macollas y el período juvenil de cada individuo. Las medias de las características de cada genotipo se correlacionaron según el coeficiente de correlación de Pearson. Se aplicó el índice de Mulamba y Mock, con una intensidad de selección del 10% para elegir los genotipos superiores. Existen altas correlaciones positivas entre el período juvenil, la altura y producción de biomasa verde. La población seleccionada fueron 23 genotipos superiores, con base en la aplicación de la suma de rangos, lo que resultó en altas ganancias de selección para los rasgos de interés. Finalmente, la selección de genotipos élite de estevia con alta producción de biomasa verde, mayor insensibilidad a la duración del período de luz diario, así como plantas más altas, son fundamentales para los futuros programas de mejoramiento de la estevia en la Sabana Brasileña.
