“…Development of winter wheat synthetics was started at CIMMYT in 2004, when winter durum wheat germplasm from Ukraine and Romania was crossed with winter Ae. tauschii accessions from the Caspian Sea basin (Morgounov et al, 2017;Gadimaliyeva et al, 2018). Independent studies indicated and confirmed that synthetic hexaploid wheat possessed considerable variation for salinity tolerance based on Na exclusion (Dreccer et al, 2004).…”

In order to determine the performance of synthetic wheat (Triticum turgidum × Aegilops squarrosa) lines under soil salinity stress conditions and to screen quantitative indices of salinity tolerance, 43 synthetic wheat lines from International Maize and Wheat Improvement Center (CIMMYT), Turkey were tested in a randomized complete block design in two replications under non-salinity (normal) and salinity stress conditions in Absheron and Ujar regions of the Republic of Azerbaijan. The results of analysis of variance (ANOVA) showed significant differences among the wheat genotypes for all quantitative morphological traits studied. Salinity stress tolerance indices, including stress sensitivity index (SSI), tolerance index (TOL), mean productivity index (MPI), stress tolerance index (STI), geometric mean productivity index (GMPI) and harmonic mean index (HMI) were calculated according to the grain yield under non-salinity and salinity stress conditions. The correlation coefficients showed that GMPI, STI, MPI and HMI were the most desirable selection criteria for high yielding and soil salinity tolerant genotypes. The results of this experiment revealed that among the studied wheat genotypes lines Nos 16 and 27 were highly tolerant but produced low grain yield. Also, lines Nos 5, 29, 15, 28, 4, 25 and 24 had the highest tolerance to salinity stress and produced the highest grain yield in both (non-salinity and salinity stress) conditions. In conclusion, it was suggested that these wheat lines are suitable for salinity stress conditions and are appropriate for hybridization with the aim of increasing salinity tolerance.

“…All segregating populations crossed with BRS Guamirim, including this male parent, remained in the same statistical group, with fewer spikelets. Gadimaliyeva et al (2018) analyzed agronomic traits in three groups of synthetic wheat and found an average of 20 spikelets per spike of wheat. Similar values were found in the present study at crossings with BRS 179.…”

“…The lack of symptoms of FHB is generally associated with tall stature and low yield; the breeding experience in China has shown that it is difficult to use these materials in breeding (Bai & Shaner, 2004). Gadimaliyeva et al (2018) studied agronomic traits in lines from synthetic wheat and found average height for all synthetic wheat and its derivatives ranging from 85 to 126 cm, with no line being considered semi-dwarf. Szabo-Hever et al (2018) indicated that smaller synthetic wheat plants had higher disease severity.…”

The objective of this study was to develop segregating wheat populations for resistance to gibberella through the introgression of synthetic wheat genes in traditional cultivars and to present the results using the backcross method. In addition, to evaluate these populations in F1RC2, agronomic aspects and type II and III resistance to Fusarium head blight (FHB). The cultivars BRS Guamirim and BRS 179 were used as male parents and three synthetic wheat cultivars (CIGM90.909, CIGM92.1666, and CIGM93.298) as female parents, both previously characterized for the reaction to FHB. Crossing and backcrossing methodological procedures were performed to provide adequate controlled conditions. The F1 (winter 2016), RC1 (summer 2016/2017), and RC2 (winter 2017) populations were developed through emasculation and pollination procedures. In the winter of 2018, segregating populations were evaluated in the field using a randomized block design. In the three generations developed in a greenhouse, it was observed that the best crossbreeding combinations, verified by the number of grains, were obtained with the male parent BRS 179. Under field conditions, all segregating populations were considered moderately susceptible and susceptible to type II resistance. In type III resistance, all segregating populations, except for CIGM90.909/BRS 179 and BRS 179, showed values above 50%. Thus, it was evident that the crossings performed with the male parent BRS 179 generated better resistance to the disease.

International Winter Wheat Improvement Program (IWWIP) was established in 1986 between the Government of Turkey and CIMMYT with three main objectives: (1) develop winter/facultative germplasm for Central and West Asia, (2) facilitate global winter wheat germplasm exchange, and (3) training wheat scientists. ICARDA joined the program in 1991 making it a threeway partnership that continues to work effectively. The germplasm developed by IWWIP as well as the winter wheat cultivars and lines received from global cooperators are assembled into international nurseries. These nurseries are offered annually to public and private entities (IWWIP website) and distributed to more than 100 cooperators in all continents. IWWIP impact has primarily been in new winter wheat cultivars combining broad adaptation, high yield potential, drought tolerance and disease resistance. A total of 93 IWWIP cultivars have been released in 11 countries occupying annually an estimated 2.5-3.0 Mha. IWWIP cooperation with researchers in Turkey, Central and West Asia and several US universities has resulted in a number of publications reviewed in this paper. Important IWWIP impacts include national inventories of wheat landraces in Turkey, Tajikistan and Uzbekistan, their collection, characterization, evaluation and utilization.
