Pitanga ( Eugenia uniflora L.) cultivation has increased rapidly around the world, but most seedlings come from sexual propagation and thus present high genetic variability and respond differently to environmental conditions. This work studied the phenology and thermal requirement of pitanga genotypes in the Brazilian semiarid. Forty‐eight genotypes were evaluated in 2017 and 2018 in an experimental farm at the Federal Rural University of Semiarid, Mossoró, Brazil. The time and thermal requirement for phenological stages from fruit pruning to harvesting, and fruit production were evaluated. Highly productive and precocious genotypes were identified, and six groups were arranged based on dissimilarity.
