In technical standards, requirements concerning quality of fresh apples are defined on the base of sensory criteria. As far as measurable traits are concerned, the standards contain only data about dimensions and weight of fruit. The estimation of numeric values of soluble solid content (SSC) is based partly on technical and economic parameters and partly on requirements of the world market. For the time being, the Commission of Normalization. negotiates the limits data about SSC that could be used for the market standard. In years 2005, 2006 and 2007, values of SSC were estimated in 18 apple varieties originated from seven countries sold in market network of the Slovak Republic. The overall average of all measurements and all varieties (n=1080) reached a value 13.3±1.2%. Variability of SSC content was mainly influenced by the apple variety. The highest contents of SCC were estimated in the following varieties: Pinova, Red Winter, Topas, Melrose, Rubinola, Jonagored and Fuji.
