Description:	Plant selection conducted in commercial orchards is mainly based on plant features. This study characterizes and selects acerola tree genotypes with promising features for cultivation in the Gurguéia Valley region, Piauí. Twenty-five genotypes were used, consisting of 15 clones (CL 03, CL 08, CL 09, CL 12, CL 13, CL 14, CL 20, CL 23, CL 26, CL 27, CL 30, CL 31, CL 33, CL 36, and CL 38) and 10 cultivars (BRS 235, BRS 236, BRS 237, BRS 238, BRS 366, Sertaneja, Costa Rita, Morena, Tropicana, and Junko). The experiment was set up in a randomized block design with three blocks and three plants per experimental unit in 4 m x 3 m spacing. A total of 40% of the genotypes evaluated showed an umbrella shape, 36% showed a semi-open shape, and 24% showed an open shape. Clones 09, 14, and 12 presented the highest cultivation potential in the region, with monthly production of 5.01, 4.30, and 3.70 kg plant-¹ per year and productivity of 4.16, 3.59, and 3. 08-ton ha-¹, respectively. Clone 27, cultivars BRS 236 and BRS 235, and clone 14 were the earliest genotypes, requiring 1,503.3, 1,535.6, 1,686.6, and 1,686.6 DD; respectively, to complete their cycle. Clones 09 and 14 stood out from the others and are potentially promising for cultivation in the Gurgueia Valley region.
