Climate change has increasingly affected Brazilian agriculture, with higher temperatures during the strawberry planting period altering crop performance. This study aimed to evaluate the agronomic performance of strawberry cultivars under different planting times, from late summer to early autumn, in Pelotas, RS, during the 2022 and 2023 seasons. The cultivars BRS DC22, BRS Fênix, and BRS DC09, developed by the Embrapa strawberry breeding program, were evaluated for yield per plant, harvest onset, number and average fruit weight, number of crowns, and physicochemical attributes. A significant genotype × planting date interaction was observed only for harvest onset in 2022. ‘BRS Fênix’ showed earlier harvest and higher average fruit weight, while ‘BRS DC22’ produced more fruits and crowns per plant. In 2023, higher temperatures during early planting reduced the influence of planting time on most variables. Fruit production was concentrated between September and November, with an early onset in July and August. ‘BRS Fênix’ exhibited greater brightness and a higher soluble solids/acidity ratio, whereas ‘BRS DC22’ produced fruits with higher acidity. The results highlight that cultivar selection and planting time definition should be adjusted according to climatic conditions to optimize earliness, yield, and fruit quality.
