Abstract
A new and distinct cultivar of black currant (i.e., Ribes nigrum L.) is provided. The flower buds of the new cultivar exhibit good tolerance to freezing during spring frosts and the time of flowering is very late. The vigorous and upright growth habit of the new cultivar renders it well amenable to mechanical harvesting. Good quality fruit is formed in high yields. The fruit exhibits an attractive glossy purple-black coloration and is particulaly well suited for juice production. Good resistance to mildew and leaf spot also are provided.
