In Vitro Cell Selection of Sugar Beet for Resistance to Culture Filtrate of the Fungus Fusarium oxysporum
A multistep in vitro cell selection was carried out on a well-proliferating callus tissue of sugar beet capable of morphogenesis. A 20-day culture filtrate of the fungus Fusarium oxysporum was used as a selective...
