| Abstract:
Cherry plum (Prunus cerasifera Ehrh.) is a relatively new crop in Estonia. It is known that cherry plum cultivars show usually somewhat lower resistance to the frost with comparison with the European plum (Prunus domestica L.) cultivars. Our main objective was to test cherry plum cultivars for their adaptation to the climatical conditions of Estonia and their potential commercial value. Cherry plum hybrid cultivars under estimation were obtained from Russian, Byelorussian and Latvian breeding programs. During 1995-2000 eight introduced cherry plum hybrid cultivars ´Alvis´, ´Karminnaya Žukova´, ´Kometa´, ´Mara´, ´Naidena´, ´Podarok Druzyam´, ´Pramen´, ´Vetraz´ and one selection Matyunin´s 9-250 as well as american cultivar ´La Crescent´ and russian cultivar ´Skoroplodnaya´ (hybrid between Prunus salicina Lindl. and Prunus americana Marsh.) were evaluated for their productivity, fruit weight, harvesting time and fruit quality characteristics in an orchard, planted in 1988-1989 at the Polli Horticultural Institute of the Estonian Agricultural University. Winter hardiness of these cultivars was estimated during winters of 1993/94, 1995/96 and 1996/97. This paper contains also the brief descriptions of the cultivars. According to our results frosts caused the different level damage practically to all studied hybrid cultivars. ´Mara´ and ´Alvis´ were the most hardy cultivars during three winters estimation. The most injured were ´Naidena´, ´Skoroplodnaya´ and ´Vetraz´. ´Mara´, ´Pramen´ and ´Karminnaya Žukova´ were the highest yielding cultivars in this trial. Fruit weight was the largest on ´Kubanskaya Kometa´ and ´Podarok Druzyam´. Fruit attractiveness and flavour were ranked highest for ´Kubanskaya Kometa´. | |
