The basic chemical characteristics of 22 quince genotypes and cultivars were determined: dry matter content, soluble solid content, the contents of organic acids, pectins, and mineral elements (nitrogen, phosphorus, potassium, calcium, and sodium). Quince fruits were harvested in the course of October and analysed at the stage of consumption ripeness after storage at 2 deg C and relative air humidity of 85%. The levels of pectins in fruits were high - the cultivar Hruskovita contained 3.51+/-0.19 g/100 g FW. The concentrations of vitamin C were also high, the cultivar Muskatova containing as much as 79.31+/-2.01 g/100 g FW. The affinity of chemical properties of the individual cultivars was expressed by means of cluster analysis and it was found out that there were no marked differences between pear-shaped (Cydonia oblonga subsp. pyriformis) and apple-shaped (Cydonia oblonga subsp. maliformis) forms of fruit.
