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
Epicoccum nigrum versicolor", "E. vulgare", "E. granulatum", "E. menispermi", and "E. neglectum". More recently, two distinct genotypes for "E. nigrum" have been identified with the combined use of DNA sequencing, morphology, physiology, and recombination factors. This indicates the existence of cryptic species, and a subsequent call to re-classify "E. nigrum" into more than one species. Epicoccum nigrum Epicoccum nigrum is a species of fungus, in the phylum Ascomycota. A plant pathogen and endophyte, it is a widespread fungus which produces coloured pigments that can be used as antifungal agents against other pathogenic fungi. The fluorescent stain, epicocconone is extracted from it. "Epicoccum
