The experiment was carried out at the Department of Processing and Storage of Plant Raw Materials of the Agricultural University of Szczecin in 2001–2002. The aim of this study was to estimate the quality and nutritive value of three patisson cultivar fruits. Salad-fruits (medium-size fruits) of all tested cultivars formed fruits of significantly greater weight, vertical and horizontal diameter in comparison with dessert-fruits (small fruits). Chemical composition of patisson fruits was significantly dependant on the cultivar and size of picked fruits. Among the tested cultivars the highest amount of dry matter, total sugars and vitamin C was obtained from the ‘Disco’ cultivar while the total nitrogen and protein was from ‘Gagat’. The highest amount of ash was found in fruits of cv. ‘Polo F₁’. Dessert-fruits contained higher amount of dry matter, total sugars, vitamin C, total nitrogen, total protein and ash in comparison with salad-fruits.
