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 oxyacanthoides found in mountain talus. This plant is an alternate host for the white pine blister rust ("Cronartium ribicola"), the vector of a pine tree disease. It is sometimes eradicated in attempts to control the rust. Small amounts of this shrub and its fruit are present in the diets of wildlife species such as grizzly bear and mule deer. Humans find it "more or less palatable". Many Native American groups collected and stored it for food. The Ojibwa cooked and ate it with sweet corn and made it into preserves, for example. The root was used medicinally. Ribes oxyacanthoides Ribes oxyacanthoides
