CHARACTERISATION OF WHEAT MUTAGEN DEPRESSION AFTER GAMMA-RAYS IRRADIATED

Here we report cytogenetic, plant growth and development characteristics of mutation induction variability of the new wheat varieties and some relationships between means of cytogenetic characteristics and different doses and types of mutagens. The strategy of investigation combined the identification of genotypes carrying specific low-sensitive to mutagen factor using cytological and morphometrical analyzes screening of mutagen treated wheat populations with the approach of comparing different varieties by breeding methods to reveal its connections and differences, specific sensitive to mutagens effects on cell and plant level. The main purposes of investigations in this area were determination of the mutagen-polluted area suitability for agriculture; determination more suitable varieties for planting on mutagen-polluted area or as a object for mutation breeding.
