Scientific potential: Within the laboratory of Plant Resistance Genetics, 16 scientific researchers are active, out of which 3 habilitated doctors, 6 doctors of sciences, 4 coordinating scientific researchers, 2 senior scientific researchers, 6 trainee scientific researchers, 4 senior laboratories.
Directions of activity: Experimental mutagenesis, in vitro techniques, biotechnological processes for inducing plant variability in order to create new valuable genotypes, intra- and interspecific hybridizations, gametic selection, haploidy, cultivation features of energy crops.
Research includes the following objectives:
- Assessment of the variability and heredity of quantitative and qualitative traits, identification of gene donor sources responsible for productivity and resistance to extreme climate factors according to F1-F4 hybrid combinations and parental forms in tomatoes.
- Improved methods of gametic (pollen) selection of lines, varieties and hybrids that combine high potential productivity with ecological resistance in order to determine valuable genotypes;
- Elucidation of genetic mechanisms for inducing the effect of haploidy, obtaining homozygous lines with increased productivity based on simple corn hybrids;
- The use of gamma radiation and in vitro culture in order to induce phenotypic variability in culture plants in order to highlight forms with characters important for improvement;
- Improving the methodology for including genetically distant species in the creation of own root interspecific genotypes of vines (V.vinifera L. x M.rotundifolia Michx.) With increased resistance to environmental factors and pathogens of the created genotypes;
- Evaluation of local garlic and onion populations in order to select valuable forms and include them in the breeding process;
- Utilization of hybrids and androsterile lines according to quantitative and qualitative traits in sorghum crops in order to increase productivity in the context of climate change;
- Determination of agrobiological peculiarities of biomass formation and energy value of Miscanthus spp. Genotypes, resistance to extreme temperatures, water deficit and other unfavorable weather conditions (strong winds, frost, snow).
Research results:
• Developed biotechnological processes to induce plant variability in order to create new valuable genotypes (lines, hybrids, varieties) with adaptability, productivity and increased resistance to pathogens and different production conditions.
• To extend the variability to tomato culture, distant hybridizations were performed, applied gamma radiation and in vitro culture as a result of which inter- and intraspecific hybrid combinations of tomatoes with increased variability of the main agronomic characters were obtained, which is an important starting material for the process. improvement. The hybrid combinations obtained were evaluated according to the type of dominance of valuable agronomic traits and the heritability of the indices that determine productivity. The research resulted in the creation of 6 varieties of tomatoes, which exceeded the previous varieties in terms of productivity, fruit quality, resistance to stressors, 4 of them (Iulihirsutian, Anatolie, Jacota and Cerrydani) were approved for cultivation in the Republic of Moldova .
• In the tritical culture, the significant influence of gamma radiation on the callus mass was established, the power of radiation being 11.01%, however, the maximum action was manifested by the genotype with a weight of 72.15%. It was found that gamma radiation influenced the process of cell division in triticale, inducing chromosomal aberrations in ana-telophase in the genotypes investigated, their frequency increasing from 11.57% to 28.20%, compared to the control of aberrant cells constituted 0% -4.56%.
• Inducers of haploidy in maize were obtained at a rate of 13-17%, of which 16 lines were selected that exceed by 47% in productivity the most efficient parental form.
• Research on sorghum crops is focused on the development of amelioration techniques that allow the expansion of diversity, the creation of the initial material for the amelioration process. As a result, 1258 sorghum lines and hybrids with heterozygous Aa1 were created, which ensure a high heterosis effect after productivity (80-90 t / ha). The hybrids obtained with the use of this heterozygote ensure a biomass yield up to 80-90 t / ha in the absence of irrigation, resistant to pollination. During that period, two sorghum hybrids (SASM 2 and SASM 3) and a sorghum hybrid x Sudan grass (SASM4) were approved for cultivation in the Republic of Moldova. The created sorghum hybrids exceed by 26-39% the approved hybrids according to the biomass productivity. At the CSTSP of the Republic of Moldova, a variety of sorghum for grains is being tested (Avantaj).
• The garlic collection includes over 40 shapes, which served as a basis for highlighting and selecting valuable shapes. As a result, a form that does not form floral stems (Moldabella) and a form with floral stems (Berechet) characterized by productivity, quality and increased resistance to unfavorable environmental factors were highlighted and evaluated. The varieties are approved for cultivation in the Republic of Moldova.
• The vine germplasm collection is maintained and completed, which currently includes 120 intra- and interspecific varieties. Interspecific vine hybrids (V.vinifera L. x M.rotundifolia Michx.) (Alexandrina, Nistreană, Malena and Augustina, Bega, Amethyst and Algumax) were created by the methodology of including genetically distant species in the creation of their own interspecific genotypes. vine roots (V.vinifera L. x M.rotundifolia Michx.). They are characterized by increased resistance to environmental factors and pathogens, have an early period of grape ripening, increased resistance to low winter temperatures of - 29oC, can be grown on their own roots in the Central and Northern areas of the Republic. Moldova. They are approved in 2019 for cultivation in the Republic of Moldova.
