Evaluation of the nursery traits of rootstocks and varieties is an important tool for optimisation of the fruit orchard plants final growing. The present experiment evaluated the standard and progressive rootstocks for the pear trees in combination with the Asian varieties of P. pyrifolia Nakai. a P. ussuriensis Maxim. in comparison with the control variety ‘Conference’ P. communis L. The evaluation was focused on such properties as affinity, growth of the tree propagated by budding, thickness of the root crown at the rootstock and the root suckering. Their interactions were tested statistically. The highest values of affinity within the nursery were achieved with the following rootstocks: ‘BET’ (96.6%), ‘FOX 11’ (95.5 %), and ‘MA’ (94.4 %). ‘Hosui’ was identified as the variety with the greatest growing capacity, with an average gain of 1238.2 mm. The most supported variety growth was exhibited by the ‘FOX 11’ rootstock, with an average gain of the trees propagated by budding of 1388.8 mm. The growth intensity itself was demonstrated most in the thickness of the root crown of the ‘BET’ (P. betulifolia) rootstock, namely 15.8 mm. The rootstock that exhibited the strongest root suckering was also ‘BET’ with 6.2 suckers per rootstock. The identified differences between the varieties and rootstocks were confirmed as statistically significant or even highly statistically significant.
