Pumiselect is a clonal Pumiselect pumila rootstock for peach and apricot. The aim of an experiment conducted in 2002-2004 was to determine the ability of Pumiselect propagation by hardwood cuttings. In autumn from one-year-old hardwood shoots 40 cm long selections were cut. The hardwood cuttings were calibrated into 2 groups according the diameter: is great than 5 mm and is less than 5 mm. In each group of hardwood cuttings, 50% of them were treated with rooting stimulator with 0.5% NAA. In the spring, hardwood cuttings were planted in the nursery 20 cm deep. In the year of planting, the rootstocks were budded. In the autumn, the quality of root system was estimated. The quality of the root system was very good. Both diameter of cuttings and rooting stimulator didn't have an influence on the root mass. The hardwood cuttings is greater than 5 mm of diameter and treated with NAA had the least number of places with outgrowing roots and the least roots in the highest part of rootstock. The thicker hardwood cuttings promoted the overhead part of rootstock.
