Effect of sublethal and lethal doses of gamma-radiation of the corn pollen on the inducing the form-bullding process

The pollen and the plants of the corn have been investigated. The aim of the work: inducing the form-building processes on the ground of utilization of the donor corn pollen to be radiated with the sublethal and lethal doses with the subsequent additional pollination by the recipient pollen. The methods of the radiobiology, genetics, cytology and biochemistry have been used as well as the gamma stand and microscopes. The radiobiological properties of the pollen radiated by the high doses of the gamma-radiation have been studied; the presence of the two mechanisms of the genetic changeability has been shown, they are: transformation and mutation ones. Determined has been the range of the doses which ensures the most genetic changeability. The transgene plants of the corn and the mutant forms to be characterized by the high content of the protein, dwarf, fast-ripening and having the increased number of corn-cobs have been obtained.
