PERSPECTIVES OF THE APPLICATION OF BIOTEC HNOLOGICAL METHODS IN SELECTION OF THE SUGARCANE SACCHARUM-OFFICINARUM L FOR RESISTANCE TO HYPOXIA

The possibility of obtaining somaclonal forms with increased resistanc e to hypoxia was demonstrated on three clonal varieties of the sugarca ne using cell selections on selective media. Two selective in vitro sy stems were developed for selection of forms resistant to hypoxia. The culture of sugarcane tissues can be used in the selection directed at the increase of resistance to hypoxia. Sugarcane plants with increased tolerance to root waterlogging were first obtained from the callus li nes, selected for resistance to the toxic analogue of methionine, ethi onine, and to anaerobic conditions. These plants can also be used in t raditional selection as donors of such a resistance.
