Publication - Primary hexaploid synthetics: novel sources of wheat disease resistance(Elsevier, 2019) Shamanin, V.; Shepelev, S.; Pozherukova, V.E.; Gultyaeva, E.; Kolomiets, T.; Pakholkova, E.V.; Morgounov, A.Climate change is leading to increased occurrence of and yield losses to wheat diseases. Managing these diseases by introducing new, effective and diverse resistance genes into cultivars represents an important component of sustainable wheat production. In 2016 and 2017 a set of primary hexaploid synthetic wheat was studied under high disease pressure: powdery mildew, leaf and stem rust in Omsk; Septoria tritici and S. nodorum in Moscow. A total of 28 synthetics (19 CIMMYT synthetics and 9 Japanese synthetics) were selected as having combined resistance to at least two diseases in both years of testing. Two synthetics (entries 13 and 18) originating from crosses between winter durum wheat Ukrainka odesskaya-1530.94 and various Aegilopes taushii accessions, and four synthetics (entries 20, 21, 23 and 24) from cross between Canadian durum wheat Langdon and Ae. taushii were resistant to all four pathogens. Pathological and molecular markers evaluation of resistance suggests presence of new genes and diverse types of resistance. The novel genetic sources of disease resistance identified in this study can be successfully utilized in wheat breeding.
Publication - Effect of climate change on spring wheat yields in North America and Eurasia in 1981-2015 and implications for breeding(Public Library of Science, 2018) Morgounov, A.; Sonder, K.; Abugaliyeva, A.I.; Bhadauria, V.; Cuthbert, R.; Shamanin, V.; Zelenskiy, Y.; DePauw, R.M.Wheat yield dynamic in Canada, USA, Russia and Kazakhstan from 1981 till 2015 was related to air temperature and precipitation during wheat season to evaluate the effects of climate change. The study used yield data from the provinces, states and regions and average yield from 19 spring wheat breeding/research sites. Both at production and research sites grain yield in Eurasia was two times lower compared to North America. The yearly variations in grain yield in North America and Eurasia did not correlate suggesting that higher yield in one region was normally associated with lower yield in another region. Minimum and maximum air temperature during the wheat growing season (April-August) had tendency to increase. While precipitation in April-August increased in North American sites from 289 mm in 1981-1990 to 338 mm in 2006-2015 it remained constant and low at Eurasian sites (230 and 238 mm, respectively). High temperature in June and July negatively affected grain yield in most of the sites at both continents. Climatic changes resulted in substantial changes in the dates of planting and harvesting normally leading to extension of growing season. Longer planting-harvesting period was positively associated with the grain yield for most of the locations. The climatic changes since 1981 and spring wheat responses suggest several implications for breeding. Gradual warming extends the wheat growing season and new varieties need to match this to utilize their potential. Higher rainfall during the wheat season, especially in North America, will require varieties with higher yield potential responding to moisture availability. June is a critical month for spring wheat in both regions due to the significant negative correlation of grain yield with maximum temperature and positive correlation with precipitation. Breeding for adaptation to higher temperatures during this period is an important strategy to increase yield.
Publication - The performance of early-generation perennial winter cereals at 21 sites across four continents(MDPI, 2018) Hayes, R.; Wang, S.; Newell, M.T.; Turner, K.; Larsen, J.; Gazza, L.; Anderson, J.; Bell, L.; Cattani, D.J.; Frels, K.; Galassi, E.; Morgounov, A.; Revell, C.K.; Thapa, D.B.; Sacks, E.J.; Sameri, M.; Wade, L.J.; Westerbergh, A.; Shamanin, V.; Amanov, A.; Li, G.D.A network of 21 experiments was established across nine countries on four continents and spanning both hemispheres, to evaluate the relative performance of early generation perennial cereal material derived from wheat, rye, and barley and to inform future breeding strategies. The experimental lines were grown in replicated single rows, and first year production and phenology characteristics as well as yield and persistence for up to three years were monitored. The study showed that the existing experimental material is all relatively short-lived (?3 years), with environments that are milder in summer and winter generally conferring greater longevity. No pedigree was superior across this diverse network of sites although better performing lines at the higher latitude sites were generally derived from Thinopyrum intermedium. By contrast, at lower latitudes the superior lines were generally derived from Th. ponticum and Th. elongatum parentage. The study observed a poor relationship between year 1 performance and productivity in later years, highlighting the need for perennial cereal material with greater longevity to underpin future experimental evaluation, and the importance for breeding programs to emphasize post-year 1 performance in their selections. Hybrid lines derived from the tetraploid durum wheat generally showed greater longevity than derivatives of hexaploid wheat, highlighting potential for greater use of Triticum turgidum in perennial wheat breeding. We advocate a model in future breeding initiatives that develops perennial cereal genotypes for specific target environments rather than a generic product for one global market. These products may include a diversity of cultivars derived from locally adapted annual and perennial parents. In this scenario the breeding program may have access to only a limited range of adapted perennial grass parents. In other situations, such as at very high latitude environments, perennial crops derived from barley or rye may have a better chance of success than those derived from wheat. In either case, development and selection of the perennial parent for adaptation to local environments would seem fundamental to success.A network of 21 experiments was established across nine countries on four continents and spanning both hemispheres, to evaluate the relative performance of early generation perennial cereal material derived from wheat, rye, and barley and to inform future breeding strategies.

Publication - Evaluation of synthetic wheat lines (Triticum durum/Aegilops tausсhii) for vegetative period and resistance to diseases(Institute of Cytology and Genetics of Siberian Branch of the Russian Academy of Sciences, 2017) Shamanin, V.; Pototskaya, I.V.; Shepelev, S.; Pozherukova, V.E.; Truschenko, A. Yu; Chursin, A.S.; Morgounov, A.The growth of the total wheat production and increase of yield stability from year to year are some of the pri-orities of agriculture in Russia. The yield of commercial varieties signi cantly diversi es due to huge losses of their potential under the in uence of negative biotic and abiotic factors. Increase of resistance to stress factors in the emerging varieties can be achievedby utilizing the diversity of the genetic resources of relat-ed wild species and genera in crosses. The results of a phenotypic evaluation of the synthetic hexaploid wheat lines of CIMMYT breeding created by crossing durum wheat varieties from Institute of Breeding and Genetics (Odessa, Ukraine) and variety Pandur from Romania (T. durum Desf., AB genome) with Aegilops (Ae. tausshii Coss., D genome), and also 15 synthetic wheat lines of Kyoto University breeding (Japan) creat ed by crossing durum wheat variety Langdon with di erent ecological forms Aegilops are presented. Research was performed on the experimental eld of Omsk SAU under conditions of southern forest-steppe of West Siberia in 2016. Between synthetics, there was revealed a genotypic di erence in the vegetative peri-od duration and resistance to diseases. Lines of hybrid combination Aisberg/Ae.sq.(511) were characterized as the most early-maturity genotypes among the lines studied. The hybrid combinations Ae.sq.(369) with va-riety Aisberg, Ae.sq.(310) and Ukr-Od 1530, Ae.sq.(223) and Pandur are characterized by complex resistance to fungal diseases. Most of the lines demonstrated high and moderate resistance to rust fungus, severity rang-ing from 5 to 70 % and severity of powdery mildew being 10–90 %. Lines derived from variety Ukr-Od 1530.94 and accessions Ae. tauschii (392); (629); (1027); (1031) and lines Langdon/Ku-2074; Langdon/Ku-2075; Langdon/Ku-2100; Langdon/Ku-2079 are character-ized by complex resistance to powdery mildew, leaf and stem rust. The synthetic lines with a complex of economically valuable traits present interest as an initial material for breeding programs. Key words: synthetic wheat; phenotyping; vegetative period; leaf and stem rust; powdery mildew; resistance.
