Abstract
We conducted graft transmission experiments for the assessment of the Blackcurrant reversion virus (BRV) resistance in currants.
Scions from Full Blossom Disease (FBD) infected Ribes rubrum were grafted onto red currant cultivars Rondom, Jonkheer, and Vitan, white currant Blanka, and black currants Viola and Öjebyn. Symptoms of BRV infection were observed and the virus was detected by RT-PCR repeatedly.
Among red cultivars the highest resistance was observed in Rondom with no BRV infection, whereas 12% and 25% of Jonkheer and Vitan plants were positive in RT-PCR respectively.
White currant cultivar Blanka was infected in 24%, black currant Viola in 11%, and Öjebyn only in 3%, the latter without any symptoms of virus infection.
