THE OCCURRENCE OF RASPBERRY BUSHY DWARF VIRUS IN RASPBERRY FIELD TRIALS IN ROMANIA

V. Isac, M. Isac, P. Mladin
Raspberry bushy dwarf virus (RBDV) is widely distributed among different raspberry cultivars throughout the world. Many infected Rubus species and cultivars do not show any symptoms but, in sensitive ones, RBDV causes yellowing, premature defoliation, leaf curling, necrosis, decrease in vigor, fruit size and weight; and fruit may be crumbly. This virus is seed-borne through pollen and ovules and is transmitted naturally in the field by pollen. Since 1990, extensive observations were carried out on the occurrence of Rubus viruses in experimental fields at the Research Institute for Fruit Growing (RIFG) Pitesti, Romania. Subsequently, a systematic study on RBDV presence has been initiated. Severe vein yellowing and partial or complete yellowing of the leaves were observed on shoots of some raspberry cultivars and hybrids. Based on serological assays (DAS-ELISA) RBDV was detected in approximately 31% of the Rubus genotypes tested including materials from the germplasm collection and from field trials. The virus appears to be widespread in Romania.
