Vaccinium corymbosum fruits are used as raw material for the food industry. It is known that the highbush berries, compared to lowbush blueberries, are richer in dry matter and total sugar content. During 2021-2022, at the Researsch Institute for Fruit Growing Pitești-Mărăcineni, Romania was organized a field trial with two genotypes and their progenies. Data were collected for: average fruit weight,size index, firmness, ph,total soluble solid, total sugar content, vitamin C, total polyphenol, flavonoid, antocyanin, lycopene and β-carotene content. The aim of this study was to compare the analysis of the fruit quality in hybrids of 'Simultan’ and 'Northblue’ cutivars. The results showed significant differences between progenies. The fruit weight varied between 0.82 and 2.05 g, the firmness oscillated between 8.13 and 28.27 N, total soluble solids reached a maximum of 17.43° BRIX, size index varied between 8.13 to 28.27, vitamin C content varied from 3.48 to 13,49 mg/100 g. Total polyphenol, lycopene and β-carotene content averaged 1296.66 mg GAE/100 G, 0.10 mg and 0.42 mg. For the blueberry breeding programme, biochemical evaluation of hybrids characteristics is an important objective.
