Sažetak
Iločka sour cherry is regional domesticated landrace grown in eastern Croatia. Landraces are characterized by significant phenotypic variability because of propagation by root suckers. The present study was undertaken to assess some physical and chemical traits of Iločka sour cherry fruits collected from originated accessions during 2015 and 2016 harvest season. The fruit of seven Iločka sour cherry accessions (IV), altogether with Oblačinska, Erdi Botermo and Rexelle, were analysed for their main physical and chemical attributes. Principal component analysis (PCA) successfully differentiated investigated genotypes correlating IV accessions with soluble solids content, total anthocyanin content, total sugars, glucose, fructose and sorbitol, Oblačinska with colour parameters, Erdi Botermo with fruit weight, whereas Rexelle correlated with titrable acidity and sucrose. Among IV accessions, IV1 stands out with high soluble solids content (20.4°Brix), soluble solids content/titrable acidity ratio (17.2), total polyphenol content (7.34 mgGAE/gFW) and total anthocyanin content (2.45 mgCGE/gFW) therefore IV1 is excellent candidate for commercialization for both, fresh consumption and processing markets, as well as for planting in amateur orchards. Further investigation of main biological and pomo-technological properties of selected IV accessions in parallel trials with standard sour cherry cultivars should be conducted.
