The thesis consists of introduction, 5 chapters, conclusions, recommendations, 263 bibliographic sources, 9 annexes, containing the main text on 130 pages, 40 figures, 46 tables. The obtained results have been published in 39 scientific papers.
Study domain: 03.00.15 – Genetics.
Research goal: establishment of a geneticaly factors; implicated in the resistance heritability of winter wheat resistance to mains pathogens causing roots diseases, and creation of the resistant sources.
Objectives: establishment of the species components, fungus strains pathogenicity, which causes root rots and ear diseases, as well as wheat genotype role in above mentioned manifestations; elucidation out the genotype x pathogen interaction influence on the reaction of some wheat quantitative indices in vivo and in vitro conditions; determination of the immunomodulatory capacity of some steroid glycosides; establishment of the temperature influence on the gene interaction of the wheat plantlet reaction to the pathogens; establishment of the heritability particularities of the wheat resistance to the root rots agents.
Scientific innovation and originality: the influence of temperature on the manifestation of genetic effects, involved in the formation of resistance character of the winter common wheat to some root rot mains agents. The solved scientific problem. The establishement of the genetic factors involved in the formation of resistance character of the winter common wheat to some root rot mains agents and the influence of interactions genotype x pathogen x conditions on their manifestations.
Theoretical significance. The elucidation of the genetic mechanisms which develop the winter wheat defence reaction in different biotic and abiotic conditions, as well as the role of steroidal origins immunomodulators.
Practical importance: the methods of identification of Fusarium fungi virulent strains, wheat resistance to root rots and treatment of caryopsis before sowing have been elaborated. Wheat’ lines with complex resistance to fungi diseases, optimal indices of productivity and capacity of the resistance heredity have been created.
Scientific results have been implemented in the Applicative Genetics Laboratory and in the Centre of Vegetal Genetics Resources of the Institute of Genetics and Physiology of Plants of the Academy of Sciences of Moldova.
