The Impact

The adaptive properties of spring wheat lines with foreign genetic material at the early stages of ontogenesis on the backgrounds of salinization with sodium chloride and prolonged flooding of seeds in water were evaluated. In the course of the work, different degrees of inhibition of growth processes were revealed, depending on the factor used and the genetic characteristics of the studied forms, a comprehensive (summary) assessment of the index of stability characterizing adaptability to adverse environmental factors was shown.

Resistance To Diseases

Introduction. The global climate change conduces spreading of main diseases of winter bread wheat (Triticum aestivum L.) and increases the yield losses caused by both these diseases and drought. Preventing the devastating impact of these factors on the yield depends on development of donors carrying the resistance genes. Aim. The diversity of new introgression wheat lines derived from complex interspecies crosses was evaluated for resistance to widespread diseases, drought and other agricultural traits. Methods. The trial was conducted consecutively during two vegetative periods (2018-2019 and 2019-2020) on the black earth area under the arid system in a control nursery design. Genetic material includes seventy-eight introgression wheat lines of different origin with two check cultivars for the arid climate zone of Ukraine. The data on nine agronomic (quantitative scores) and five plant pathological (point scores) traits were collected and subjected to both variance and correlation analysis to comprehend the contribution of the factors towards general diversity and connections between the characters. Results. Most lines were resistant to rust species due to the successful introgression of alien Lr, Yr and Sr genes from all sources involved in hybridization. High long-term resistance to stem rust was observed mainly among the derivatives of the collection sample H74/90-245 from Bulgaria, whose genetic background was favorable for generating a positive effect of 1BL.1RS translocation on both productive and adaptive traits in southern Ukraine and the ability to combine with other resistance genes. The yield traits did not correlate with the resistance to diseases except stem rust (Rsp = 0.34**) and Septoria blight (Rsp = −0.23*). Resistance to stem rust correlated with the grain and protein yield, test weight and flour density, which may be due to the presence of translocation 1BL.1RS. Negative correlation was observed between quality traits and grain yield, but quality traits mainly positively correlated with each other. The plant height had the highest contribution to grain yield followed by volume of 1000 kernels and WTK. Conclusions. The introgression lines were found to be diverse and potential for use in the wheat improvement programs for resistance to the diseases or drought in Southern Ukraine.

Aim. T. kiharae (AtAtGGDD, 2n=42) is a source of high protein and gluten content, resistance to many diseases. Сommon wheat lines with the introgression of T. kiharae genetic material were obtained in order to enrich T. aestivum L. gene pool. The aim of this study was to assess the impact of T. kiharae genetic material on the grain quality of T. aestivum/T. kiharae introgression lines. Methods. The composition of the high molecular weight glutenin subunits was analyzed by SDS-PAGE. Evaluation of the most important traits of grain quality (hardness, protein and gluten content, gluten quality) was carried out according to GOST. Results. Сomparative analysis of the composition of high molecular weight glutenin subunits of introgressive lines and their parental forms allowed us to identify lines with novel alleles of Glu-1 loci, specific for T. kiharae. For most of the introgression lines T. aestivum/T. kiharae hardness, protein and gluten content were higher than for parent wheat varieties. Conclusions. Introgression of T. kiharaegenetic material in the genome of common wheat had a positive effect on all studied parameters of grain quality except the gluten quality. Keywords: common wheat, T. kiharae, glutenin, SDS-PAGE, quality of grain.
