In vitro prediction for salt tolerance in wheat [electronic resource].

Includes references.

Calluses of three salt tolerant wheat genotypes and their hybrids was obtained from mature embryos were grown on MS medium supplemented with different NaCl concentrations. Growth rates of calluses decreased as the salinity levels were increased in the culture medium. There were highly significant differences among the tested genotypes and their hybrids in response to salt stress in callus growth rate. The results showed that callus growth rate and plant regeneration of hybrids were less decreased as salt concentration was increased compared with that of parents. Sakha-69 and hybrid (Sakha-69 x Giza -157) were the most tolerant and scored high percentage in plant regeneration. Free proline content im;reased parallel to the increase of salinity.
