“…Increasing the resistance of wheat to diseases can be achieved due to the genetic resources of closely related wild and cultivated species and genera and artificially created on their basis amphiploids of different genomic structure (Morgounov et al, 2018). The method of remote hybridization in soft wheat was able to transfer useful genes for resistance to diseases (Kovalyshyna and Dmytrenko, 2017) and pests (Bhatta et al, 2018), drought, frost and salt resistance (Reynolds et al, 2007;Ahmadi et al, 2014). The number of results with the successful use of the obtained hybrids indicates the prospects of involving introgressive recombinant variability in the selection of soft winter wheat (Lyfenko et al, 2014).…”

Resistance to common diseases has been studied and a selection assessment has been made of improved introgressive lines created by repeated crossing of amphiploids, primitive lines or collection specimens with modern varieties of soft winter wheat. There is a low frequency of combining group stability with high yield and grain quality. It was found that the genetic environment of some introgressive lines is favorable for the positive effect of rye translocation 1BL.1RS on both economically valuable and adaptive traits in the south of Ukraine and the possibility of combining with other resistance genes. There was no correlation of resistance to powdery mildew, leaf and stem rust with yield both in the absence and presence of natural infectious background and a weak positive relationship (Rsp = 0.26 **) yield with resistance to Septoria and yellow rust in only one variant of the experiment. In most cases, there is a weak significant positive correlation between resistance with protein content and weight of 1000 grains, as well as between the resistance of the lines to various diseases, which is obviously a consequence of artificial selection for group resistance. Selected selection lines (E2792_14, AIL1161_16, E218_09, E212_09, AIL1073_16) with foreign polygenic complexes of resistance to rust diseases, high values of weight of 1000 grains, protein content, as well as morphological features; which are characterized by high productivity, adaptability, tolerance to low agrophones, baking quality. The lines are devoid of many negative qualities inherent in wild species, can be a promising source of resistance to these diseases and are of interest for further breeding work in southern Ukraine, provided the preservation of foreign gene complexes.

To realize the genetic potential of the productivity of bread winter wheat varieties, it is necessary to maintain a certain level of plant resistance to disease. Resistance donors may lose this property as a result of changes in the virulence of the pathogen and defeat of the genetic systems of plant resistance. This makes it necessary to search for new resistance sources and donors to leaf diseases. Our researches were conducted using field, laboratory and mathematical-statistical methods. Phenological observations, accounting, evaluation and harvesting were conducted according to currently accepted methods. 86 bread winter wheat samples from the 4th WWSRRN CIMMYT were studied for resistance to leaf diseases in our research during 2014–2016. The manifestation of variability depended significantly on the genotype for three diseases. The highest genotype influence was obseved in resistance to septoria disease, where it was 81%. On average the highest indicator of resistance (7.7) to powdery mildew during the three years of research was observed in the mid-late ripening samples. The mid-early ripening group was considered to be the most adapted to the powdery mildew pathogen in the Northeastern Forest-Steppe. The highest average indicator of resistance (7.5) to brown rust for the three years of research was found in the early ripening group. The samples of the mid-ripening group were most adapted to the brown rust pathogen. The highest average resistance to septoria disease was also found in the early ripening group. The best adaptation to septoria disease was observed in mid-late ripening samples. 36% of the samples were resistant to three diseases. As a result of the research, a number of CIMMYT samples were isolated from the 4th WWSRRN, which exceeded the standard in resistance to powdery mildew, brown rust and septoria disease. They were characterized by better performance. Valuable forms for breeding work that can be resistance donors to leaf diseases were identified among them.
