Five years research of the biological and pomological characteristics of some pear varieties are presented in this paper. 18 pear varieties with different ripening time were included in the research. Some of investigated varieties are new bred (Turandot, Norma, Karmen, Monica), some of them are famous as resistant to Fire Blight (‘Harrow Delight’, ‘Harvest Queen’, ‘Harrow Sweet’, ‘Honey Sweet’) and some of them belong to group of old varieties that have been less investigated in our conditions (‘Starking Delicious’, ‘Abbe Fetel’, ‘Packams Triumph’, ‘Conference’, ‘Magness Highland’, ‘Guyot’). All varieties were compared with standard varieties (‘Williams’, ‘Precoce Moretini’, ‘Bosc,s’). Demonstrative orchard was established in 1997 at the Faculty farm-Trubarevo near Skopje. The trees were grafted on BA 29 quince rootstock and for those varieties that had not affinity with quince, we used inter stock pear variety Cure. Research was conducted during the period of 2003-2007. The following parameters were investigated: blossom, ripening of the fruits, growth of the trees (TCSA, volume of the crowns), yield, pomological characteristics of the fruits and content of the soluble dry matters and acids. The results showed that some of the pear varieties are characterized with a good production attributes, resistant to Fire Blight, pear sucker and to some a biotical factors, with good quality of the fruits. In the first group, the best characteristics gave variety Norma, from resistant variety group good results gave variety Harrow Sweet, and from old variety assortment for our conditions, good results gave ‘Packams Triumph’. These varieties can be recommended for cultivation in our climatically conditions.
