This study aimed to evaluate the physicochemical quality of thirty-fve acerola genotypes produced during two growing seasons in a Semi-arid region and to identify the best ones with potential for fresh consumption based on a multivariate selection index. Fruit of each genotype were harvested during two growing seasons at the maturity stage red-ripe, characterized by full red skin color. After harvest, the fruit were evaluated for diameter, mass, fesh frmness, soluble solids (SS), titratable acidity (TA) SS/TA ratio, ascorbic acid content and skin color. A multivariate selection index (SI) was applied for scoring and ranking the genotypes for fresh consumption based on red-ripe fruit physicochemical quality. According to the results, all physicochemical attributes had high variability among genotypes. The SI was a powerful tool for identifying genotypes with high potential for fresh consumption, since it allowed selecting genotypes with multiple desirable traits. In the frst and second growing seasons, the SI identifed the genotypes PROG 052 (SI = 76.1 and 78.9), BRS Rubra (SI = 74.1 and 99.5), Cabocla (SI = 72.3 and 70.7), Costa Rica (SI = 61.2 and 73.8) and PROG 069 (SI = 68.1 and 72.4) as the most promising ones for fresh consumption due to the presence of multiple desirable traits such as high diameter, mass, fesh frmness, SS, and SS/AT ratio, as well as lower acidity.  aFruit quality  aMalpighia emarginata  aAcerola  aConsumidor  aGenótipo  aMelhoramento Genético Vegetal  aPós-Colheita  aQualidade  aAscórbico ácido  aAtributos físico-químicos da fruta  aDescritores  aDiversidade genética1 aVILVERT, J.
