• Abstract The paper states that the problem of developing valuable starting material for breeding new varieties is very acute. In this situation, the authors consider it necessary to offer new methods of inducing aberrant or recombinative plant variability without using GMOs but attracting own hidden reserves of seeds to increase their germination, seedling growth, productivity, and yield of future agricultural products. For this purpose, the research team suggested treating wet seeds with physical factors by mobilizing forces and releasing energy reserves of seeds, activating physiological and biochemical processes at the early stages of their germination. The research showed that the more water is in the seed cells, the more immobile the rotating DNA molecule is and the more vulnerable the constituent genes are subject to irradiation. The authors found that an increase in seed humidity before irradiation led to a higher yield of chromosomal aberrations, expanding the spectrum of their economically valuable traits to be transmitted to the next generations. The authors presented the results of their studies on the effect of electrophysical factors of seed treatment. The procedure included water-thermal seed treatment with alternating electric current and subsequent laser irradiation depending on doses, type, and nature of influences stimulating the growth and development of their seedlings.
