Fall Gold Raspberry bud deformity
I have some fall gold raspberry bushes and at the end of this season quite a few of them started having this bud deformity. The buds were slightly chlorotic, bunched, and never seemed to open into a flower. There were no obvious signs of pests or fungus. Any idea of what this could be? Maybe a virus?

"I’ve seen this before. Mutation occurs within the bud. No sure of cause (physiological). When canes are cut back this winter, one hopes won’t be a problem next year."
