An assessment of the regenerative capacity was made for 20 highbush blueberry cultivars and 3 half-highbush blueberry cultivars introduced in Belarus, based on 9-year research results. Has been established that the regeneration ability of the green cuttings of blueberry is genetically determined with varying degrees of severity in one or another cultivar. The results obtained allowed to classify blueberry cultivars according to their root-forming ability into three groups: easily rooted ((‘Elizabeth’, ‘Hardyblue’, ‘Northland’), medium rooted ((‘Blueray’, ‘Coville’, ‘Croatan’, ‘Darrow’, ‘Denise Blue’, ‘Herbert’, ‘Jersey’, ‘Northcountry’, ‘Reka’, ‘Rubel’) and difficult to resist (‘Bluecrop’, ‘Bluetta’, ‘Bluerose’, ‘Carolinablue’, ‘Duke’, ‘Earliblue’, ‘Nelson’, ‘Northblue’, ‘Patriot’, ‘Weymouth’). It is reliably shown that one hundred varieties of this crop, possessing a higher rootforming ability, produce plants with large biometric parameters of the above-ground sphere. The blue cuttings of highbush and half-highbush blueberries have a satisfactory regenerative capacity, which makes it possible to use this method of vegetative propagation for replication and to obtain planting material of this culture in Belarus.
