F. S.  aPerformance of sweet potato genotypes in Brazilian regions.h[electronic resource]  c2022  aThe average yield of sweet potato (Ipomoea batatas (L.) Lam.) in Brazil is below the crop potential, and appropriate cultural practices and more productive cultivars are needed to improve crop yield. The Beauregard sweet potato cultivar, originally from the United States, has shown high productive potential. This study evaluated the performance of features of agronomic importance of the Beauregard cultivar in comparison to local cultivars and eight sweet-potato clones in Brazilian regions. For that purpose, two sets of experiments were carried out. The first set evaluated eight sweet potato clones and cultivars Beauregard, Olho Roxo and Ourinhos in Brasília?DF and Itabaiana?SE using as criteria two foliage and six root traits. In the second set, two sweet potato clones (9 and 75), and Beauregard, Brazlândia Branca and Canadense cultivars were evaluated in Piacatú?SP, Brasília-DF, PAD-DF, Canoinhas-SC and Altamira-PA, for the traits: commercial, non-commercial, and total yield. Beauregard presented little foliage production but great root yield across the different environments. Since it has low dry matter content, acceptance of this cultivar may be limited in some regions. None of the sweet potato clones showed stable yield to justify a commercial launch.  aBiofortification  aPlant adaptation  aSweet potatoes  aBatata Doce  aIpomoea Batatas  aCultivar  aCultivar Beauregard  aCultivar Olho Roxo  aCultivar Ourinhos1 aSILVA, G.
