Pomološke osobine sorti trešnje u beogradskom Podunavlju

Pomological properties of twelve sweet cherry cultivars of different maturing time were studied at the Experimental Station 'Radmilovac' of the Faculty of Agriculture in Belgrade during the five-year period (2005-2009). The aim of this study was choosing of the best cultivars for commercial growing. The average harvest time was from May 12 to June 18. High productivity was obtained in cultivars 'Van', 'Early Van Compact', 'Lapins', 'Stella', 'Bing' and 'Drogan's Yellow', while low productivity was obtained in 'Merchant', 'Summit' and 'Burlat'. The largest fruits had cultivar 'Vega' (9.2 g), and the smallest one 'Primavera' (4.0 g). Soluble solids content ranged from 12.7% ('Primavera') to 18.2% ('Drogan's Yellow') and it was correlated with the time of maturation. The highest organoleptic scores for fruit quality got cultivars 'Bing' and 'Summit'. Among early season cultivars the best results showed 'Burlat' and 'Souvenir des Charmes' ('Bigarreau Moro'), among mid season cultivars 'Van', 'Summit' and 'Vega', and among late season cultivars 'Bing' and 'Lapins'.Pomološke osobine 12 sorti trešnje različitog vremena zrenja proučavane su na Oglednom dobru 'Radmilovac' Poljoprivrednog fakulteta iz Beograda u periodu od pet godina (2005-2009). Cilj rada je bio izbor najboljih sorti za komercijalno gajenje. Ispitivane sorte prosečno su sazrevale od 12. maja do 18. juna. Po dobroj rodnosti ističu se sorte Van, Rani Van kompakt, Lapins, Stela, Bing i Droganova žuta, dok su najmanju rodnost imale Merčant, Samit i Birla. Najkrupniji plod imala je sorta Vega (9,2 g), a najsitniji Primavera (4,0 g). Sadržaj rastvorljive suve materije kretao se od 12,7% (Primavera) do 18,2% (Droganova žuta) i bio je u korelaciji sa vremenom zrenja. Najveću organoleptičku ocenu za kvalitet ploda dobile su sorte Bing i Samit. Od ranih sorti najbolje osobine pokazale su Birla i Suvenir, od srednje poznih Van, Samit i Vega, a od poznih sorti Bing i Lapins
