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 malvaceum source in habitat gardens. It thrives under oaks in bright dry conditions, and in many other locations. Pollination ecologists have reported the plant important as a honey plant for attracting large numbers of native bees. Ribes malvaceum Ribes malvaceum, the chaparral currant, is a member of the Grossulariaceae (gooseberry family). It is native to California and northern Baja California, where it occurs from sea level to , in chaparral, foothill oak woodland, and closed-cone pine forest habitats. "Ribes malvaceum" typically grows tall. This perennial shrub lacks the characteristic nodal spines which are demonstrated on the stems of many other members
