Immature embryo- derived calli from the wheat accession 1908 were irradiated with gamma rays at 2.58×10^-1C/kg. The frequency of somaclonal variation in the second generation (C₂R₂) went up to 25%, being about four times as high as that of the non- irradiated counterpart (R₂). From the calli- irradiated regenerant's progeny, one elite line with high yield potential, early maturity, resistance to both scab disease and lodging was isolated and officially registered as a new variety named Hezu 8.
