Mratinić E., Popovski B., Milošević T., Popovska M. (2011): Evaluation of apricot fruit quality and correlations between physical and chemical attributes. Czech. J. Food Sci., 29: 161-170.The fruit of apricot (Prunus armeniaca L., Rosaceae) has been used as food in FYR Macedonia since a long time ago. The chemical organic matters from the fruit is a kind material for food processing and has potential nutritional, medical and commercial values. The results based on fruit physical and chemical analyses clearly showed that different apricot genotypes have very important contents of soluble solids, individual sugars, and titratable acidity in limited soil and climatic conditions. In addition, the contents of these chemical compounds in some genotypes were higher than those in the control cultivar Hungarian Best. Using the PC analysis (PC1 = 32.13%, PC2 = 22.86%, and PC3 = 18.32%), apricot genotypes were separated into groups with similar physical and chemical attributes. These relationships may help to select a set of genotypes with better fruit quality performances which, in our study, might be indicated in DL-1/1/04, DL-1/2/03, D-1/04 and K-5/04.

To carry out domestication, five genotypes (B1, B2, R, VG and RK) were isolated from natural populations by selection of black elderberry (Sambucus nigra L.). The most prominent biological-technological characteristics were studied during fruit flowering and ripening. Flowering proceeded in the period from mid-April to the 1st decade of June, while ripening lasted from the 1st decade of August to the 1st decade of October. The largest inflorescences were found in genotype R (14.32 cm in diameter). The highest number of berries per inflorescence (on average, 280), the largest berry (on average, 0.21 g), and the best fruit quality (17.19% dry matter, 11.50% sugars, 35 mg vitamin C, and 2.58 g/l total colored matter) were all demonstrated by genotype VG. In all isolated genotypes fruit demonstrated biologically high quality, which makes it a good raw material desirable for diverse forms of processing. Its high yield level, pronounced resistance to disease agents and pests, as well as adaptability to adverse conditions are a recommendation for organic-based production
