Ugni molinae Turcz. known as "murta" or "murtilla" is a native species from Central and Southern Chile. This plant has attracted interest as a fruit-growing alternative due to the distinctive fragrance and taste of the fruit. With the objective of evaluating the fruit of different murta accessions collected from the 7th to 10th Region of Chile, a sample of 20 fruit per accession was analyzed for physical and chemical parameters. The highest frequencies for the evaluated parameters were as follows: polar diameter 0.87 cm; equatorial diameter 1.01 cm; unitweight 0.45 g; seeds perfruit 10.27; color of epicarp: red; color of pulp: white; soluble solids 19.4 °Brix; fructose in fruit 21.6 mg gpf-1 (grams offresh product); fructose in seeds 6.33 mg gpf-1 ; sucrose in fruit 68.6 y 134.2 mg gpf-1; sucrose in seeds 8.66 mg gpf'; titrable acidity 8.2 meq Na OH 100 gpf-1; pH 4.29 and ascorbic acid 63.4 mg gpf-1.

Keywords: Chilean wild fruit, physical characteristics, chemical characteristics.
