The challenge facing raspberry production on a regular basis is knowledge of both the biology of growth and development and the characteristics of aboveground growth –pseudostems arising from the rhizome of raspberry, as dependent on the nature and position of adventitious buds from which they develop. In terms of the formation and realization of the bearing potential, fruiting canes as aboveground growth are classified according to the rooting degree of the supporting rhizome. The two-year research on the bearing potential of cv. ‘Polka’ as dependent on the type of aboveground growth indicates differences that are likely to affect the cost-effectiveness of raspberry production. The aboveground growth developing from primary adventitious buds positioned on horizontally growing roots exhibits significantly higher bearing potential compared to that arising from lateral buds positioned on etiolated belowground growth. The number of fruits per cane ranged from 310.20 to 429.15. Fruit characteristics were significantly affected by harvest date
