dc.description.abstractContinuous changes in climate, desertification, reduction of arable land, increase in salted land, in the conditions of continuous growth of the population, the problem of providing food and food security to humanity arises, the solution of which is one of the challenges of the 21st century that requires universal efforts. At the same time, abiotic stresses, which are the cause of 50% of global yield losses, are the motivation for the creation of new stress-resistant varieties of crops using modern technologies. The salt resistance of that idea as a physiological manifestation with a polygenic component is characteristic in the modern processes of selection management. This work presents studies of salt tolerance of three valuable varieties of potatoes cultivated in Armenia, using biochemical and DNA-markers. Classical agronomic, molecular-biological, genetic-mathematical methods are used in the researches. In order to induce salt stress and provocation background in plants, 50, 100 and 150 mmol solutions of NaCl were used. The results have shown that 11S-globulin of all varieties are polymorphic, forming different electrophoresis spectra and protein formulas. It is also evident that plants with different spectra of the same varieties react differently to salt stress. The DNA restriction regions of the saltresistant variants are significantly longer than those of the non-salt-resistant forms. Thanks to the biochemical and RFLP markers, it has been possible to establish salt tolerance loci, to identify and list plants with a salt-tolerant spectrum of the same variety, which can be nominated as new salt-tolerant varieties for breeding stock producers.eng
