In the conditions of the Republic of Belarus there were studied 9 promising pear (Pyrus L.) varieties of Byelorussian and foreign breeding on suitability for juice extraction by direct pressing. Those varieties varied by their resistance to diseases (scab - Venturia pirina Aderh. - ascigerous stage, Fusicladium pirinum Fck. -conidial stage; pear Septoria blight - Mycosphaerella pyri (Auersw.) Boerema - ascigerous stage, Septoria piricola Desm. - conidial stage) and by winter hardiness. By frost extent there were distinguished highly winter hardy varieties such as 'Vidnaya' and 'Chizhovskaya', winter hardy varieties 'Kudesnitsa', 'Prosto Mariya', 'Avgustovskaya rosa', 'Krasavitsa Chernenko', 'Rossoshanskaya krasivaya' and medium winter hardy ones 'Dukchmyanaya' and 'Lagodnaya'. All varieties studied on foliar scab resistance were included into the group of relatively resistant varieties. Fruits of all varieties except 'Vidnaya' and 'Rossoshanskaya krasivaya' were included into the group of relatively resistant ones. According to the data of organoleptic evaluation, fruits of the following pear varieties appeared to be the most suitable for unclarified juice extraction by direct pressing: 'Rossoshanskaya krasivaya', 'Krasavitsa Chernenko' and 'Lagodnaya' (4.5 points), just suitable were the fruits of the varieties 'Vidnaya', 'Prosto Mariya' and 'Chizhovskaya' (4.3 points). Fruits of all studied varieties are suitable for fresh consumption.
