“…Significant differences were observed for the production of multi-cellular structures and plantlets: N6 and B5 media were found better than MS medium (Sun et al 1980); C17 medium respectively better than B5, N6, and MS medium (Park et al 1995); Potato II medium better than B5 medium, N6, MN6 and C17 (Wang and Hu 1984). Today, some of the defined basal media (C17, N6 and NPB99) are preferred and, are in common use (Eudes and Amundsen 2005;Gonzalez and Jouve 2005;Gut et al 2006;Ponitka and Slusarkiewicz Jarzina 2007). These authors have reported regeneration on specialised media, 190-2, R9, or hormone free MN6, GEM (Eudes and Amundsen 2005;Karsai and Bedo 1997).…”
