Feijoa [Acca sellowiana (Berg) Burret] is a Brazilian native fruit with few commercial‐level plantations and high agroindustrial potential. A genotype evaluation experiment was conducted since 1996, aiming to obtain fruits based on the agronomical parameters, however, the selection based on chemical composition had not been evaluated to develop a new cultivar. Based on the aforementioned, this study aimed to discriminate seven accessions of feijoa by its nutritional composition, phenolic compounds, and antioxidant activity using multivariate analysis (principal component analysis and multivariate contrast), aiming the potential production of a new cultivar with better nutritional value and high antioxidant capacity. Feijoa husk presented high content of ashes, lipids, proteins, carbohydrates, phenolic compounds, and antioxidant activity, comparing to feijoa pulp. However, just feijoa pulp was selected to multivariate analysis, because it is the fruit edible part. Data variability was explained in 78% and the feijoa pulp accessions were discriminated in four groups related to its characteristics. The accession 5 discrimination can be explained by the high content of ashes, carbohydrates, soluble solids, phenolic compounds, and antioxidant activity. Accession 6 was also discriminated by the high content of total acidity, pH and proteins; and low content of soluble solids. Feijoa accessions may be indicated to increase the plant selection through hybridization with the other accessions, to produce new cultivars with better nutritional composition and antioxidant capacity. For instance, accession 5 is the most suited fruit to human consumption and is a potential plant to become a new cultivar.
