Selection of stevia elite genotypes aiming at the development of cultivars adapted to the Brazilian Savanna

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