Choice of orchard system is one of the major factors, on which pear crop size and quality depend. The purpose of this research was to assess the influence of two training systems involving trees trained to different number of leaders on growth, yield, and fruit quality of three pear cultivars. The study was conducted in 2001–2012 near Wrocław (south-western Poland). One-year-old trees of ‘Carola’, ‘Dicolor’ and ‘Erika’ cultivars on the Quince S1 rootstock were planted in the spring 2001 using 3.5 m between rows and a variable in-row spacing: 1.7 m (Drilling form with 3 leaders) and 1.2 m (Güttingen – V system with 1 leader). More vigorous growth was observed from more sparsely planted trees under the Drilling form. The total per-tree yield during 2002–2012 was decreasing as the planting density increased. No differences were observed on yield per hectare between the tested systems. The Drilling trees produced significantly heavier and larger fruit than the trees trained to the V-Güttingen system.
