Proizvodne osobine i kvalitet ploda novointrodukovanih sorti jagode

The paper presents results of the research into productive qualities and fruit quality of the ‘Clery, ‘Joly’ and ‘Dely’ strawberry cultivars, conducted during 2012 and 2013. The fruit mass and yield per crown were significantly higher in the ‘Joly’ cultivar. A significantly higher number of fruits per crown and higher yield per crown were recorded in the second year of harvest, whereas the fruit mass was significantly higher in the first year. The highest values of fruit quality parameters (RSM and total acidity) were recorded in the ‘Joly’ cultivar, whereas the highest values of the total sugars, pH and the RSM/total acidity ratio were recorded in the ‘Dely’ cultivar. A better chemical composition of the fruit of the examined cultivars was determined in 2012. In the overall result, the ‘Joly’ cultivar demonstrated the best productive qualities, whereas the ‘Dely’ cultivar was superior from the aspect of the fruit quality.U radu su prikazani rezultati dvogodišnjih proučavanja (2012−2013.) proizvodnih osobina i kvaliteta ploda jagode sorti ‘Clery’, ‘Joly’ i ‘Dely’. Vrednosti mase ploda i prinosa po bokoru bile su značajno veće kod sorte ‘Joly’. Značajno veći broj plodova po bokoru i prinos po bokoru zabeležen je u drugoj godini plodonošenja, dok je masa ploda bila značajno veća u prvoj godini. Najveće vrednosti parametara kvaliteta ploda (rastvorljiva suva materija i ukupna kiselost), zabeležene su kod sorte ‘Joly’, dok su najveće vrednosti sadržaja ukupnih šećera, pH i odnosa RSM/UK zabeležene kod sorte ‘Dely’. Hemisjki sastav ploda, svih proučavanih sorti, bio je izraženiji u 2012. godini. Ukupno posmatrano, najbolja proizvodna svojstva ispoljila je sorta ‘Joly’, dok je sa stanovišta kvaliteta ploda, superiornost pokazala sorta ‘Dely’
