“…Given the unpredictable environmental factors in the GE interaction studies, different models (GE, GE interaction, and AMMI), were developed to elucidate the effect of genotype, environment, or interaction; they are still used in breeding studies (Kendal, 2015;. In addition, the GT biplot technique has been used for a long time by many researchers to understand the effect of genotype and environment on the relationships between agronomic, physiological and quality characters, and yield (Yan and Tinker, 2006;Kendal and Dogan, 2015;Akcura et al, 2016;Oral et al, 2018). The GT biplot is used to compare varieties based on multiple traits and to define them based on these traits.…”

The specification of the most convenient cultivars based on multiple trait indices is a new approach in durum wheat (Triticum durum Desf.) adaptation and stability studies. This approach helps to define the best cultivar based on multiple traits and multiple locations because cultivars are affected by unpredictable climatic conditions. Some traits (ears per square meter, spike length, number of grains per spike, spike yield, and leaf chlorophyll content among others) can be produced for primary breeding purposes because they are influenced by environmental factors and indirectly affect grain yield and quality. Therefore, in the present study, the new genotype × yield × trait (GYT) biplot approach was used to identify the best cultivar among 10 durum wheat cultivars based on multiple environments (8) and multiple traits (18). Cultivar ranking was examined by a superiority index that combined yield and other target traits with the GYT biplot. The general adaptability of each cultivar in terms of all the traits indicated differences based on environment means, and significant differences were found between varieties for the GYT biplot. In the GYT biplot, yield-trait combinations clearly indicated the most stable cultivars, whereas in the genotype × trait (GT) biplot, the best cultivars were not defined for all traits. 'Sariçanak' was ranked as the best combination of physio-morphological traits with grain yield, 'Zühre' was the best for more quality traits, and 'Güneyyildizi' was the best for both physio-morphological and quality traits in the GYT biplot. The GYT biplot combines traits with yield and can help the visual identification of the best cultivars; it is better than the GT biplot method.

“…This is in agreement with Bardsley et al [39], who explained that the landrace Kirik is retained in Northeast Anatolia villages primarily because the baking qualities in the flour are appropriate for the local bread, lavash. Further studies are necessary to determine the grain quality components and properties that led to this preference, something that has already started in that country [40]. In other cases, such as the bread named "Pane Nero di Castelvetrano" from Sicily (Italy), the association between its end-use quality and the use of a specific landrace to elaborate it has been established [41].…”

Recovery of Wheat Heritage for Traditional Food: Genetic Variation for High Molecular Weight Glutenin Subunits in Neglected/Underutilized Wheat

Club wheat (Triticum aestivum L. ssp. compactum (Host) Mackey), macha wheat (T. aestivum L. ssp. macha (Dekapr. & A.M. Menabde) Mackey) and Indian dwarf wheat (T. aestivum L. ssp. sphaerococcum (Percival) Mackey) are three neglected or underutilized subspecies of hexaploid wheat. These materials were and are used to elaborate modern and traditional products, and they could be useful in the revival of traditional foods. Gluten proteins are the main grain components defining end-use quality. The high molecular weight glutenin subunit compositions of 55 accessions of club wheat, 29 accessions of macha wheat, and 26 accessions of Indian dwarf wheat were analyzed using SDS-PAGE. Three alleles for the Glu-A1 locus, 15 for Glu-B1 (four not previously described), and four for Glu-D1 were detected. Their polymorphisms could be a source of genes for quality improvement in common wheat, which would permit both their recovery as new crops and development of modern cultivars with similar quality characteristics but better agronomic traits.

“…A two hundred pure-line selected from Turkish wheat landraces which stored Turkish National Gen-Bank used as experimental material in this research. While selecting research materials, care was taken to include the provinces with the greatest diversity in wheat landraces and to include material from every province in which wheat landraces were grown (Akcura, 2006). Information about the origins of pure lines and sampling locations were provided in Fig.…”

“…Bread wheat landraces grown in Turkey exhibit great variation. Gen-Banks were established to preserve this diversity and several wheat cultivars have been collected and preserved for years (Akcura et al, 2016). Mamluk et al (1997) and Mamluk and Nachit (1994) assessed a series of genotypes composed of Turkeyoriginated local wheat cultivars through cluster and PCA analyses to find out new resistance sources against bunt disease (Tilletia foetida and Tilletia caries) in durum wheat and identified 26 new resistance sources against bunt disease.…”

The present research was conducted to determine the reactions of 200 pure lines selected from bread wheat landraces collected from 18 provinces and seven regions of Turkey against bunt disease (Tilletia foetida) under field conditions for 3 years. Bunt disease reactions of pure lines were assessed based on the infected spike/total spike ratio. For visually assessed materials, the GGE-biplot method, where G = genotype effect and GE = genotype-by-environment effect, was used to group the reactions against bunt disease. Fifty-nine pure lines showed high resistance (with infection rates ranging from 0.1 to 10%); 24 in the moderate resistance (with infection rates ranging from 10.1 to 25%); 75 in the moderate susceptibility (with infection rates ranging from 25.1 to 45%); 38 in the susceptibility (with infection rates ranging from 45.1 to 70%) and finally four in the highly susceptibility (with infection rates of >70.1%). PC1 and PC2 of the GGE-biplot graph created over the years explained 76.49% of the total variation. The GGE-biplot graph provided efficient identification of resistant genotypes. The lowest PC1 values and PC2 values close to 0.0 explained the resistance of pure line to bunt disease best. The resistance of pure lines to bunt disease over the biplot decreased from the first section through the last section. Based on the results of present study, 19 pure lines (located within the first circle of the biplot graph) were selected for resistance breeding programmes against the diseases.
