Abstract
Abstract The Embrapa Cerrados pitaya breeding program developed five superior genotypes of different species. The objective of this work was to evaluate the yield capacity of these five pitaya genotypes under the edaphoclimatic conditions of the Federal District. The experiment was carried out at the Embrapa Cerrados in Planaltina, DF. The five selected pitaya genotypes were evaluated, as well as a parent genotype used in the breeding program. Length (CF), diameter (DF) and mass (MF) of all fruits were evaluated, as well as the length/diameter ratio (CF.DF-1), number of fruits per plant (NF.PL-1), production per plant (kg.PL-1) and estimated productivity (t.ha-1). BRS Luz do Cerrado and BRS Lua do Cerrado presented larger and heavier fruits, while BRS Minipitaya do Cerrado presented the smallest fruits. CPAC Roxa and BRS Granada do Cerrado presented more rounded fruits. BRS Granada do Cerrado had the highest yield capacity in the two evaluated crops. The results obtained prove the importance of genetic breeding and the selection of superior genotypes more adapted to the region of cultivation, in order to guarantee greater profitability and products of better quality to rural producers and consumers.
