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 menziesii the flower. The sepals are fuchsia or purple. The petals are white and extend forward to form a loose tube from which the stamens emerge. The plant fruits purple gooseberries which are edible but are mainly seeds with little fruit, generally regarded as unpalatable. The plant's spines also make collecting fruit difficult. "Ribes menziesii" is cultivated as an ornamental plant for native plant and wildlife gardens, in areas of suitable climate, such as coastal California. It is valued for its attractive spring blooms. Ribes menziesii Ribes menziesii, the canyon gooseberry, is a species of currant found only in California and
