Performance of sweet potato genotypes in Brazilian regions

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