asia.k68@mail.ruThe goal and tasks of the project:Project objective:
«Genotyping of wheat germplasm using functional molecular markers for key genes that determine resistance to biotic and abiotic stresses».
Tasks:
1. Phenotyping and genetic-breeding evaluation of the collection of wheat varieties and lines from the international KASIB nursery (at least 80 accessions) in contrasting ecological zones of Kazakhstan (Almaty and Kostanay), differing in temperature and moisture regimes; including the assessment of field drought tolerance and determination of the drought tolerance index.
2. Genotyping of wheat accessions using no fewer than 20 functional molecular markers targeting key genes that determine resistance to biotic stresses:
Vrn (vernalization response), which defines the plant’s requirement for vernalization;
Ppd (photoperiod response), which determines the plant’s reaction to day-length extension; and Lr genes (leaf rust resistance), associated with resistance to leaf rust caused by
Puccinia recondita.
3. Genotyping of wheat accessions using functional molecular markers for a key gene determining resistance to abiotic stresses:
Dreb-B1 (dehydration responsive element binding), responsible for cellular hydration and associated with drought tolerance. Conducting an integrated analysis of phenotyping and genotyping data to identify climate-resilient wheat genotypes, and selecting genotypes that exhibit high yield potential and resistance to adverse environmental factors.
Interim project results for 2025: Phenotyping and genetic–breeding evaluation of the collection of wheat varieties and lines from the international KASIB nursery were carried out in contrasting ecological zones of Kazakhstan (Almaty and Kostanay), which differ in temperature and moisture regimes. Field drought tolerance and the drought tolerance index were assessed. Under the conditions of the Almaty region, phenological observations and evaluation of 124 spring wheat accessions were conducted. Based on the structural analysis of productivity components, 22 wheat accessions demonstrating the highest values for the complex of productivity traits and 51 accessions with average productivity levels were selected. Phytopathological evaluation and productivity assessment made it possible to identify 64 wheat accessions exhibiting an immune reaction (IT-0) to leaf rust and showing high productivity. High NDVI values (0.50–0.83) were recorded in 72 accessions. In the Almaty region, 27 samples wheat accessions were selected that combined a high biomass index with field drought tolerance. The assessment of morphological traits in the Almaty region revealed high diversity in the collection regarding the length of the last internode and spike exertion, allowing clear adaptive patterns to be identified. The most valuable samples for the arid conditions of the Almaty region were eight accessions (Lutescens 48-204-03, Lutescens 393/05, Lutescens 932, Stepnaya 259, Liniya 4-10-16, Lutescens KS 140/08-3, Lutescens 1300, Hordeiforme 829), which are characterized by a moderate length of the last internode and high spike exertion. These traits ensure efficient heat exchange and preservation of reproductive organs during periods of severe stress.
Similar comprehensive studies, including phenotyping and genetic selection, were conducted in the Kostanay region. Fifty-nine accessions were selected, featuring a combination of leaf rust resistance, drought tolerance, and high productivity. Based on biomass index, 37 accessions were identified with high NDVI values (0.55–0.67) and were also characterized by leaf rust resistance. Correlations between biomass accumulation and grain yield were evaluated. Twenty-seven wheat accessions were selected for their high values across a complex of productivity traits. A wide variability in the length of the last internode and spike exertion was observed in the Kostanay region. It was determined that the greatest adaptation to the moderately arid climate was exhibited by 14 accessions with medium internode length and high spike exertion (Lutescens 932, Lutescens 48-204-03, Lutescens 2102, Pamyati Azieva, Saratovskaya 29, Lutescens 8-108-1, Lutescens 1300, Novosibirskaya 41, Lutescens 90-12, Kargala 223, Liniya 9-25-016, 107/00i, F6[(119x96) x113]). Correlation analysis between the studied traits was performed. As a result of evaluating spring wheat varieties and lines from the KASIB nursery, 22 accessions were selected in the Almaty region and 23 accessions were selected in the Kostanay region, all of which exhibited a high biomass index, strong field drought tolerance (DSI ≤ 0.50), and high productivity. Significant differences were identified in key yield indicators and the drought tolerance index (DSI). High-yielding and promising lines and varieties—Hordeiforme 2264, Annushka, Kargala 223, Liniya 19003, Bezenchukskaya 139, and Leukurum 1469-21—were identified, distinguished by strong field drought tolerance and low drought tolerance index values.
The study is distinguished by a high level of scientific rigor: comprehensive research was carried out, including phytopathological and genetic–breeding evaluations on a large volume of experimental material tested in contrasting ecological zones of Kazakhstan (Almaty and Kostanay).
The practical significance of the results and their potential for future commercialization are confirmed by the selection of more than 20 wheat accessions with a high biomass index, strong field drought tolerance, and high productivity. These accessions will be incorporated into the breeding process as candidates for new wheat varieties and represent valuable material for breeding aimed at improving wheat drought tolerance.
