Two 4x-4x (intra-Tub) cultivars (‘Bintje’ and ‘Delta’) were used as standards. The 4x-2x (FDR) and 4x-4x (DTO) strategies were equivalent for all traits but they presented superior performance when compared to the 4x-4x (intra Tub) scheme (as a group) for total tuber yield (TTY), commercial yield (CY), and plant vigor (PV). No differences among breeding schemes were observed for three other traits: eye depth (ED), plant uniformity (PU), and haulm maturity (HM).  apotatoes  avarieties  aBatata  aSolanum Tuberosum  aAvaliação  aCultivar Dias Curtos  aDiseases  aEstrategies  aShort-day  aSolanum plureja1 aARAGÃO, F.
