Results of Utilization of Chernobyl Radio Mutant in Breeding Programmes of Triticum aestivum L

A large spectrum of mutations was observed as a result of winter wheat T. aestivum L. irradiation for two consecutive vegetative seasons (during 1986-87) in the fields close to the ruined reactor of the Chernobyl Nuclear Power Station. Mutants taken from the different generations (L147/91, BC 47 square head, dwarf 20104/89) were used for development of the varieties Lybid, Yasochka and Tsarivna to utilize traits from the mutants such as hardiness, drought tolerance, disease and lodging resistance and bread quality. These varieties were included in the State Variety Register of Ukraine, while another one, Lisova Pisnya is included in the list of perspective varieties. (author)
