    Identification of novel quantitative trait loci linked to crown rot resistance in spring wheat
    (MDPI, 2018) Erginbas Orakci, G.; Sehgal, D.; Sohail, Q.; Ogbonnaya, F.C.; Dreisigacker, S.; Pariyar, S.R.; Dababat, A.A.
    Crown rot (CR), caused by various Fusarium species, is a major disease in many cereal-growing regions worldwide. Fusarium culmorum is one of the most important species, which can cause significant yield losses in wheat. A set of 126 advanced International Maize and Wheat Improvement Center (CIMMYT) spring bread wheat lines were phenotyped against CR for field crown, greenhouse crown and stem, and growth room crown resistance scores. Of these, 107 lines were genotyped using Diversity Array Technology (DArT) markers to identify quantitative trait loci linked to CR resistance by genome-wide association study. Results of the population structure analysis grouped the accessions into three sub-groups. Genome wide linkage disequilibrium was large and declined on average within 20 cM (centi-Morgan) in the panel. General linear model (GLM), mixed linear model (MLM), and naïve models were tested for each CR score and the best model was selected based on quarantine-quarantine plots. Three marker-trait associations (MTAs) were identified linked to CR resistance; two of these on chromosome 3B were associated with field crown scores, each explaining 11.4% of the phenotypic variation and the third MTA on chromosome 2D was associated with greenhouse stem score and explained 11.6% of the phenotypic variation. Together, these newly identified loci provide opportunity for wheat breeders to exploit in enhancing CR resistance via marker-assisted selection or deployment in genomic selection in wheat breeding programs.

    Genetic gains in grain yield in spring wheat in Turkey
    (The Scientific and Technology Research Council of Turkey, 2017) Akin, B.; Sohail, Q.; Unsal, R.; Dincer, N.; Demir, L.; Geren, H.; Sevim, I.; Orhan, S.; Yaktubay, S.; Morgounov, A.
    Genetic gain for grain yield was evaluated in 35 Turkish spring wheat varieties released between 1964 and 2010. The germplasm comprised varieties developed by the East Mediterranean Agricultural Research Institute (ARI) in Adana, the Maize Research Station in Adapazarı, and Aegean ARI in İzmir. Out of 34 varieties studied, 24 were selected from CIMMYT germplasm. The trials were conducted during 2009?2013 at the same three sites. Average yearly genetic gain for all varieties was 30.9 kg/ha or 0.62%. The top five highest yielding varieties were all released after 1998: Ziyabey, Menemen, and Meta (İzmir), and Karatopak and Ceyhan (Adana). Plant height had a clear tendency to decrease over time. Genetic gain in yield was associated with genetic gains in harvest index (0.51%), the number of spikes/m2 (0.29%), and the number of grains/spike (0.26%). Kernel size and biomass did not change over time and represent traits to be explored in the future. The newest varieties combined higher yield with yield stability. Resistance to leaf rust contributed greatly to yield genetic gain. Turkish breeders made a substantial impact on national grain supply and food security. Future breeding strategies shall combine the utilization of CIMMYT germplasm, a diverse modern gene pool, and genetic resources in an integrated national breeding program.
