The article provides results of studying the output percentage of green stem cuttings of seven varieties of Highbush blueberry (Vaccinium corymbosum L.) subject to the dates of cutting preparation, type of shoot and its metamerism in agroecological conditions of the Rightbank Forest Steppe of Ukraine. It is found that green stem cuttings of Highbush blueberry varieties under review display low regenerative ability and are characterized with medium rooting ability. The optimal procuring and planting for rooting dates for the shoots fall within the stage of their intensive growth, which lasts from the first decade of June till the second decade of July. The level of regenerative capacity for the cuttings is determined by the type of cutting and its metamerism. Basal three-node cuttings have displayed essentially improved rooting ability as compared to the apical and medial cuttings.
