Abstract
As part of the study on the effect of viruses on the growth and fruiting of red raspberry cultivars, drupelet set of fruit was studied. Clones of four cvs., Fairview, New-burgh, Sumner and Willamette were infected with black raspberry necrosis (BRNV), raspberry mosaic (RMV), tomato ringspot (TomRSV) and raspberry vein chlorosis (RVCV). Significant reduction in drupelet set, expressed as crumbliness, occurred only in the TomRSV-infected clones of ‘Sumner’ and ‘Fairview’, and for the latter, it occurred only on those plants which showed relatively severe symptoms of decline.Keywords
