Abstract

During 1975 and 1977—1979 studies were carried out on the fungus diseases of experimentally cultivated arctic bramble (Rubus arcticus L.). The most common pathogenic or weakly pathogenic fungi isolated from the diseased clones were Cylindrocarpon destructans (Zins.) Scholten and Fusarium avenaceum (Cda ex Fr.) Sacc. Some other Fusarium species and Botrytis cinerea Pers. ex Fr. were rather uncommon. Didymella applanata (Niessl) Sacc. and plenty of pycnidia of Phoma spp. were established on nearly withered clones; among the isolates were P. exigua Desm. var. exigua Maas, Phoma spp. and Coniotbyrium fuckelii Sacc. (con. st. of Leptosphaeria coniotbyrium (Fuck.) Sacc.). Isolates of little significance were identified in the whole from 26 fungal genera.
