In the last 30 years, pears orchards area diminished dramatically in Romania due to several factors, the most important being the sensitivity to some pests (pear psylla - Cacopsylla pyricola Förster) and diseases (fire blight - Erwinia amylovora Burrill). In the same time, the market demand for pears is increasing and the prices are continuously high. The aim of this study is to present the behaviour of some new Romanian pear disease resistant genotypes, produced at the Voineşti Research Station for Fruit Growing and planted in the Experimental Orchard of the Faculty of Horticulture within USAMV Bucharest. Six varieties and two new hybrid selections grafted on quince (CTS 212), on pear (Farold 40) and on own roots, in vitro propagated, were analysed. The planting distances varied from 3.0 x 0.8 m, for Parallel U to 3.0 x 1.6 m, for Trident canopy. The study presents the comparative biometrical data for each genotype respectively: average tree height, type, number and average length of annual fruiting shoots, trunk cross sectional area. Estimation of yield and fruits characteristics at the harvest moment are detailed.
