New and prospective peer varieties are estimated by their resistance to scab, fruit biochemical indices (sugar, dry matter and acid, including ascorbic acid, content), fruit organoleptic properties and crop performance. The varieties Skoroplodnaya, Sochinaksya Krupnoplodnaya, Nektarnaya, Avgustovskaya, Slavyanka and Sochinskaya Urozhajnaya are notable for their field resistance to scab. It is acceptable to use amenable varieties which have a complex of outstanding agronomic parameters for receiving resistant ones during breeding. Fruits of Malva and Luchistaya peers stand out for sugar aacumulation (14.63 and 17.07% respectively). The varieties Khokhlatka, Rassvet, Sochinskya Krupnoplodnaya have the maximum ascorbic acid amount (10.56-10.74 mg/100 gram). The studied varieties can be divided on 3 groups according their yields in the 1 years of fruiting: high-yielding (more than 13 kg per a tree) Chernomorskaya, Yantarnaya, Skoroplodnaya, Sochinskaya Urozhajnaya, Rassvet, Dushitsa, Malva; medium-yielding (10-13 kg per a tree) Sochinskaya Ananasnaya, Williams, Cure, Slavyanka, Avgustovskaya, Sochinskaya Krupnoplodnaya; low-yielding (less than 10 kg per a tree) Yasnotka, Bere Bosk, Kholhlatka, Luchistaya, Surpriz. The follow varieties are notable for a complex of agronomic parameters (adaptability, fruit chemical composition, taste, crop performance, resistance to diseases and others): Sochinskaya Krupnoplodnaya (Bon Louise x Spadone), Slavyanka (Dekanka Osennyaya x Bere Clerzho), Rassvet (Bere Bosk x Pamyat Kongressa), Vega, Chernomorskaya, Yantarnaya, Verbena (the last 3 are received by open pollination of the variety Bere Bosk).
