Nearly isogenic lines can serve as one of the best objects for such research. In order to create isogenic lines crossing of dwarfing analogues with respective recurrent varieties was performed and homozygotisation of genotypes was carried out. The aim of the work was to estimate by complex of quantitative traits the degree of recovery of the genetic background of recurrent forms in dwarfing analogues of tall wheat varieties, which have different alleles of dwarfism genes Rht 8 , Rht - B 1 , Rht - D 1 and gene of sensitivity of photoperiod Ppd - D 1 depending on combination of crossing and the number of saturations, to determine descriptiveness of separate traits of the said complex for discrimination of lines and expediency of further becrossing. As the research methods structural analys...

A practical algorithm for determining the probabilities of transmission of the odd chromosome separately through male and female gametes in selfpollination of hemizygous hybrids from the equation p 2-(1 + f 1-f 4) × p + f 1 = 0 is proposed, where p is the probability of the formation of viable gametes with the considered chromosome and f 1 and f 4 are the empirical frequencies of the corresponding homozygotes with and without the trait. The probability of transmission of an alien univalent chromosome through pollen (p ♂) is associated with the frequency of its transmission through the egg cell (p ♀) in backcrosses and in self-pollination (1-f 4) by the equation p ♂ = 1-f 4 /(1-p ♀). The calculated empirically dependent estimates of the probabilities of transmission of the added chromosome through the egg cell p ♀ = 18.7% and through pollen p ♂ = 4.3% correspond to the empirical frequencies obtained for backcrosses. The coefficients of the gamete selection V ♀ = 0.748 and V ♂ = 0.172 are calculated, and the expected segregation for the alien trait controlled by a dominant gene located in the added chromosome is determined-with the trait : without the trait is 0.222 : 0.778 in F 2 ; 0.187 : 0.813 in equational and 0.043 : 0.957 in certational backcrosses.

The variation of protein content and its relationship to agronomic traits of introgression wheat lines were studied to determine the differentiating ability of environment, a value of breeding traits from new sources and the relevancy of assessment methods. Methods. Growing plants under different conditions was combined with the laboratory methods for determining quality. Results. An average protein content of the lines (9.7–15.5 %) was higher in the wide-row crop and in drouth years, and the range of variation was wider in dry years in the wide-row crop, but in favorable years in the solid crop. A stable positive correlation of protein content with gluten content (0.87–0.96) and sedimentation value (0.58–0.90), and the negative correlation with yield was established. Conclusions. The parameters of plant resistance to diseases and harsh agricultural backgrounds, the determination of protein content by several methods and the differentiating ability of the environments with opti...

A combination of fungal diseases and drought can cause significant yield losses of winter wheat (... more A combination of fungal diseases and drought can cause significant yield losses of winter wheat (Triticum aestivum L.). It is known that alien traits introduced through wide hybridisation contribute to breeding of cultivars with a higher yield potential in arid environments. In this study, the impact of alien genes on the main agronomic traits in the arid environments of the Southern Steppe of Ukraine was analysed. The lines were grown under the arid conditions in 5 and 10 m 2 plots in the 2019-2021 growing seasons. Eight agronomic and six plant pathological traits were assessed and subjected to statistical analysis to comprehend the diversity and connections between the features. Due to the successful introgression of alien genes from all sources involved in hybridisation, most of lines were resistant to one of the rust species. The lines derived from the genotype containing the translocation 1BL.1RS in the karyotype and Triticum timopheevii in the pedigree were resistant to all rust species. There was a negative correlation between the protein content and grain yield in 2020 (r = −0.40***), and a weak positive correlation was found between the grain yield and resistance to yellow rust (R sp = 0.19* in 2019 and R sp = 0.26*** in 2020) or tolerance to Septoria leaf blotch (R sp = 0.27***). Under drought conditions, the grain yield reduced by 32.5% in 2020 and ca. 70% in 2021. The lines containing alien genes Lr42 and Hs showed a higher grain yield than the recurrent and standard ones. For further breeding, eighteen lines with a high TKW, protein content, and grain yield, and resistance to drought or disease were identified, and four promising drought-tolerant lines have been selected.
