The material for the study used the following varieties - Favorite glutton, blizzards - created through the action of gamma rays, line 418, Colossus Myronivschyny - by hybridization Sun (NDMS 0.005%) and Kalynova (Dub 0.1%) - action chemical mutagens, cornflower - termomutahenez. Optimal doses were chosen for selection and of mutations. The doses of gamma rays - commonly used for relevant research on mutation breeding - 100, 150, 200 and 250 Gy. Concentrations NES - 0.01% and 0.025%, NMS - 0.0125% and 0.025%. DMS concentrations (dymetylsulfat) 0.0125, 0.025 and 0.05% respectively and dub (1.4 dysdiazoatsetylbutan) 0.1 and 0.2%. Varieties that were established using gamma-rays showed the specificity of mutagenic depression only in terms of pollen fertility, but this figure with the same inherent values ??and was generally unstable to radiation sort of sun. The most informative on mutagenic depression in M1 generation plants winter wheat soft indicators were similarities and survival of plants, pollen fertility and yield performance structure, plant height, grain weight of main spike, thousand grain weight. All these indicators with high index had a relationship with the concentration of mutagen, but using dub depression may not even appear on these indicators. The action of the same mutagen reduced frequency of chromosomal aberrations, gamma rays induce restructuring mainly on the type of bridge, and chemical mutagens fragments, and at higher doses specificity becomes more blurred.
