| Cenchrus ciliaris L., a forage grass of wide distribution in the north-west of Argentina, is a tetraploid (4x = 36) and obligate apomictic species. One way of obtaining novel germplasm is by induced mutations. In this work, physical and chemical mutations are combined with in vitro selection procedures seeking for new germplasm, with emphasis on salinity and drought tolerance. Mature seeds of Cenchrus ciliaris L. cv Biloela were subjected to treatments with X rays (400 Gy) and ethyl methanesulphonate (EMS) water solution (5.5 mM for 24 h). To perform in vitro selection, after 7 days of EMS or X rays treatments, germinated seeds were transferred to tubes containing Murashige and Skoog medium supplemented with NaCl or mannitol to simulate salinity and... |
