| Abstract:
Objectives of sour cherry breeding were high yield, self-compatibilty, high fruit quality and resistance to, or tolerance of, spring frost, Monilinia spp., Blumeriella jaapii and Prunus necrotic ringspot virus. Four new cultivars have been released: ‘Karneol‘(‘Köröser‘ x ‘Schattenmorelle‘),‘Morina’(‘Köröser’x’Reinhardts Ostheimer‘), ‘Safir’ (’Schattenmorelle‘ x ’Fanal‘) and ‘Topas’(’Fanal‘ x ’Kelleriis16‘) and three clones have been shortlisted: 5,55 (’Köröser‘ x clone 2,40), 13,122 (’Kelleriis16‘ x clone 17,5) and 19,130 (’Köröser‘ x ’Röhrigs Weichsel‘). In most years they do not achieve the high yield of ‘Schattenmorelle’, but they are more resistant to brown rot (Monilinia spp). and leaf spot (Blumeriella jaapii) and are well suited for canning and processing. The main problem in sour cherry breeding is to achieve high self-compatibility. Self-compatibility is a quantitative characteristic and its origin and inheritance are unknown. In general, there was more success in progenies with non-related parents than in selfings or sib-crossings. | |
