title: Developing New Cultivars of <i>Prunus</i> × <i>Rossica</i> Erem. And Clonal Rootstocks at the Krymsk Experiment Breeding Station
abstract: Abstract The paper considers the possibilities of expanding the assortment of plum cultivars in world production by hybridising large-fruited myrobalan plum ( Prunus cerasifera Ehrh.) cultivars with those of Japanese plum ( Prunus salicina Lindl.) and other diploid stone fruit species. Because of many years of breeding work in Russia, cultivars of a new hybridogenous species Prunus × rossica Erem. (Russian plum) have been created, which can ensure a stable supply of fresh fruit from late June to
