Potato genotypes and environments under potato in the Brazilian Cerrado biome

The objective was to estimate the physiological and productive performance of potato genotypes in two organic cultivation systems. No trials were conducted, being one in a protected and on in an open-field environment. A randomized complete block design with four replicates and five treatments (genotypes 'Agora', 'Atlantic', 'BRS Ana', 'BRSIPR Bel' and 'BRS Claro') was used. Physiological, productive characteristics and defects associated with tubers were obtained. The protected environment is the most appropriate to produce organic potatoes under the evaluated conditions. Genotypes 'BRSIPR Bel' and 'BRS Ana 'exhibit a high productive potential in organic conditions.
