The author presents the results of estimating the resistance of a number of the pear introduced cultivars and hybrid forms to scab in the Western Part of the Right-Bank Lisosteppe of  Ukraine among which oligogenically resistant ones were not revealed. They were divided into immunological groups as follows: practically resistant Gyeorgiyevskaya Rannyaya, olet and the hybrid 38/16, almost not susceptible to the disease Devo, Jankoiskaya Pozdnyaya, Lagodnaya, Clapp Favourite, Yasachka, Prosto Mariya and the forms 39/1, 1/19, 1/22, 1/3, 1/30. The both groups should be included into the breeding process.

Key words: pear, cultivar, hybrid form, scab, symptom, resistance.
