Blackcurrant material from the gooseberry ("Ribes grossularia"), the red currant ("Ribes rubrum") and the flowering currant ("Ribes sanguineum"). The resulting offspring were further back-crossed to "R. nigrum". Cultivars produced include 'Tisel' and 'Tiben' in 2000 and 'Ores', 'Ruben' and 'Tines' in 2005. Further cultivars 'Polares' and 'Tihope' are being tested. Since 1991, New Zealand has become an important centre for research and development, as its temperate climate is particularly suitable for cultivation of the crop. Breeding programmes are concentrating on yield, large fruit size, consistency of cropping and upright habit. In North America, there is a need for this fruit to
Ribes canthariforme Ribes canthariforme Ribes canthariforme is a rare North American species of currant known by the common name Moreno currant. The plant is native to southern California, having been found in San Diego County, California (Laguna Mountains and surrounding slopes) and in western Riverside County (Elsinore and San Jacinto Mountains). It is a member of the local chaparral plant community. The most recent estimates indicate that there are about 70 individual plants remaining. Most of these occur on land within Cleveland National Forest, and since there are few serious threats the species is not otherwise specifically protected. "Ribes canthariforme" is a
