Cassava (Manihot esculenta Crantz) plays a strategic role for food security, agro-industry, and smallholder farming systems in tropical countries. In this context, validating genotypes under diverse field conditions represents a critical step for cultivar recommendation. This study evaluated the agronomic performance of ten sweet cassava genotypes in two contrasting environments of the Goiás Cerrado (Araçu and Porangatu) during the 2020/2021 growing season. A randomized complete block design with three replications was used, and productive, morphological, and root-quality traits were assessed. Combined analysis of variance revealed significant effects of genotype and location for most traits, with a significant Genotype × Location interaction for root yield. Principal component analysis (PCA) indicated positive correlations between root yield and starch yield, as well as between plant height and shoot yield. All genotypes exhibited high yield potential, surpassing the regional mean. Cultivar BRS 429 showed superior performance and lower environmental sensitivity, indicating greater yield stability and favorable productivity and quality attributes for the Goiás Cerrado.
