American blueberry (Vaccinium corymbosum L.) is demanding for cultivation in terms of agroecological conditions, but with proper planting and care of plantation, primarily the selection of an adequate cultivars is profitable fruit species. In the area of Cetingrad, there is a plantation of American blueberry in organic cultivation with four cultivars, and ten more cultivars in the experimental part of the plantation. By monitoring the morphological and phenological characteristics of all 14 cultivars, unique characteristics were recorded and presented in this paper, and based on the obtained results, a conclusion was made to determine which cultivars are most suitable for cultivation in this area. The description of the morphological characteristics of the blueberry cultivar was followed according to the UPOV (International Union for the Protection of New Plant Species) descriptor for the blueberry. The phenology of the cultivars was monitored according to BBCH (Biologische Bundesanstalt, Bundessortenamt und CHemosche Industrie) scale. Cultivars Darrow, Patriot and Spartan were the first to finish flowering, and thus fruit growth. Cultivars Bonus, Darrow, Duke, Patriot and Spartan indicated fastest fruits growth than other cultivars. The cultivar Duke was the first to be ripe for picking fruit, and it lasted the longest during the harvest period, so it proved to be a very suitable cultivar. Cultivars Duke, Bluecrop, Ivanhoe, Patriot, Spartan and Toro showed benefits for organic cultivation in the area of Cetingrad, since they started ripening the earliest and had the longest period when the fruits were ripe for picking, and the fruits are in these cultivars big.
