The paper presents evaluation of the effect of two intensities of winter pruning on cropping and fruit quality of sour cherry cv Oblačinska. With 4 x 2 spacing and pyramidal crown as training system, light pruning, including removal of suckers and vigorous and upright shoots, and severe pruning, including removal of vigorous branches and considerable thinning of bearing trees, were employed. It has been established that the increase of pruning intensity leads to increase in fruit size of sour cherry cv Oblačinska and its fruit ratio. Soluble solids content of the fruit is very high and remains the same after pruning, whereas the total acids content markedly increases in case of severe pruning. Severe pruning causes substantial yield reduction per unit of arable land and decrease in yield efficiency defined as relation between yield quantity and annual growth of trunk cross-sectional area. However, yield efficiency defined as yield quantity per unit of crown volume adequately increases with more intensive pruning. Intensity of pruning is not an important factor as regards regularity of fruit set.U radu je ispitivan uticaj dva intenziteta zimske rezidbe na rodnost i kvalitet ploda Obla- činske višnje. Razmak sadnje je 4 x 2 m, a oblik krune je uska piramida. Primenjena je slaba rezidba sa uklanjanjem vodopija, bujnih i uspravnih letorasta i jaka rezidba sa uklanjanjem bujnog prirasta i značajnim proređivanjem rodnog drveta. Sa povećanjem intenziteta rezidbe krupnoća ploda kao i randman mesa ploda se značajno povećavaju, ali se zato smanjuje visina prinosa koja se dobija po jedinici površine. Sadržaj rastvorljive suve materije je redovno visok i ne menja se pod uticajem različitog intenziteta rezidbe, kao i sadržaj ukupnih kiselina
