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
Allium nigrum not supported by molecular data which indicate "Allium israeliticum" Fragman & R.M. Fritsch, as a distinct new species. WCLSPF recognises both as distinct species. The name "nigrum" (Latin: black) is derived from the colour of the ovaries. The plant is a frequent ornamental in European and North American gardens, having been introduced in the early twentieth century. It is produced in Taean and Seosan in South Korea. Allium nigrum Allium nigrum, common name black garlic, broad-leaved leek, or broadleaf garlic, is a Middle Eastern species of wild onion. It lacks the onion or garlic scent shared by most of the
