The tests were conducted in the region of Gostivar, Resen, Kratovo and Veles. ‘Tiranka’ is a winter traditional pear variety (Pyrus communis L.). It starts to blossom in the first to the second decade of April and it flourishes earliest in Veles, and at the latest in Resen. It forms solid, medium-sized fruit with an average weight of 175.8 g, with a long handle and with an average 2.8 seeds in the fruit. The largest fruit is given in the region of Gostivar (214 g). The strongest and firmer are the fruits of the Veles region. The fruits contain an average of 15.3% soluble dry matter, 14.2% total sugars and 0.27% total acids. The best appearance and taste are the fruits of the Resen region. Regarding the investigated properties, statistically significant differences were found between the samples depending on the genotype, the climate and the orographic conditions.
