Developing New Cultivars of <i>Prunus</i> × <i>Rossica</i> Erem. And Clonal Rootstocks at the Krymsk Experiment Breeding Station

Abstract The paper considers the possibilities of expanding assortment plum cultivars in world production by hybridising large-fruited myrobalan ( Prunus cerasifera Ehrh.) with those Japanese salicina Lindl.) and other diploid stone fruit species. Because many years breeding work Russia, a new hybridogenous species × rossica Erem. (Russian plum) have been created, which can ensure stable supply fresh from late June to September complement common cultivars. A description is given for best adaptive, high-yielding good taste high canning qualities — ‘Kubanskaya Kometa’, ‘Globus’, ‘Gek’, ‘Iyulskaya Roza’, ‘Dynnaya’, ‘Kolonnovidnaya’, ‘Podarok Sad-Gigantu’. efficiency their cultivation using intensive technologies own-rooted plants, as well clonal rootstocks bred at Krymsk Station, has shown. It recommended carry out Russian medium vigorous like Kuban 86, Evrika 99, Zarevo, Fortuna dwarf VVA 1, Best, Upryamets VSV 1.
