Trials were conducted in two successive years under contrasting temperature and moisture conditions during spring growing season, thus, the environmental effects On average, 1000-seed weight, protein, wet gluten and yellow pigment contents were higher in durum than in bread wheat in both years. On the other hand, the --and total tocopherols was higher in bread than in durum wheat. The content of total phenolics and antioxidant capacity was similar for both species. Higher temperatures and lower precipitations resulted in larger kernels, higher total protein content, as well as gluten, but negatively influenced antioxidant properties, total phenolics and lipid soluble antioxidants content. Based on ANOVA (analysis of variance), all sources of variation for each of the nine quality-and antioxidant-related traits were highly significant (P < 0.01). Average variances of studied traits associated with environmental factors were generally larger (41.6%) than those for genetic factors (23.9%) and genotype by environmental interaction effects (33.6%). Especially high environment variance was recorded for antioxidant capacity. Both, genotype and genotype by environment interaction had significant effects on wet gluten and lipid soluble antioxidants.

On average, bread wheat had significantly higher concentration of total sulphur-rich (S-rich) and sulphur-poor (S-poor) subunits of gliadins, as well as total low molecular weight (LMW) and high molecular weight (HMW) subunits of glutenins than durum wheat. However, durum wheat had higher concentration of S-rich c-gliadins and S-poor D-LMW-glutenins, but did not possess S-poor x-gliadins. The concentration of disulphide bonds and total cysteine was higher in the durum gluten than that in the bread gluten, as well as antioxidant capacity (on average 90.6 vs. 85.9 mmol Trolox Eq kg À1 , respectively). In contrast to the bread wheat, the concentration of HMWglutenins was negatively associated with extensibility, as well as resistance to extension in durum wheat flour dough.

Soluble free forms of total phenolics, flavonoids, PVPP (polyvinylpolypyrrolidone) bound phenolics, proanthocyanidins and phenolic acids were investigated. In addition, the correlation coefficients between total antioxidant capacities and the concentration of different soluble free phenolic compounds, as well as between soluble free total phenolics and phenolic acids, flavonoids and PVPP bound phenolics were determined. Significant differences in the content of aceton/water extractable total phenolics, PVPP bound phenolics and phenolic acids between and within two wheat species were found. On the average, durum wheat samples had about 1.19-fold higher total phenolic compounds and about 1.5-fold higher PVPP bound phenolics than bread wheat samples. Three phenolic acids, ferulic, caffeic and chloro...

Trials were conducted in two successive years under contrasting temperature and moisture conditions during spring growing season, thus, the environmental effects consider the influence of “hot/dry” and “cool/wet” season. On average, 1000-seed weight, protein, wet gluten and yellow pigment contents were higher in durum than in bread wheat in both years. On the other hand, the average content of α-, β+γ- and total tocopherols was higher in bread than in durum wheat. The content of total phenolics and antioxidant capacity was similar for both species.

Twenty-four agronomic traits were evaluated over 3 years under fully irrigated, rainfed and drought treatments. Grain yield was the most sensitive trait to water deficit and was highly correlated with above-ground biomass per plant and number of kernels per m 2 . The germplasm was structured into four subpopulations. The association of 46 SSR loci distributed throughout the wheat genome with yield and agronomic traits was analyzed using a general linear model, where subpopulation information was used to control false-positive or spurious marker-trait associations (MTAs). A total of 26, 21 and 29 significant (P < 0.001) MTAs were identified in irrigated, rainfed and drought treatments, respectively. The marker effects ranged from 14.0 to 50.8%. Combined across all treatments, 34 significant (P < 0.001) MTAs were identified with nine markers, and R 2 ranged from 14.5 to 50.2%. Marker psp3200 (6DS) and particularly gwm484 (2DS) were associated with many significant MTAs in each treatment and explained the greatest proportion of phenotypic variation.

Ninety-six diverse wheat genotypes were laboratory tested for germination and growth response under osmotic stress induced by polyethylene glycol (PEG). Germination percentage, mean germination time, coleoptile length, shoot length and shoot growth rate were compared under stress (− 0·4 MPa) and control (0·0 MPa) conditions. The same genotypes were previously grown in field trials exposed to drought stress during the anthesis and/or grain filling growth stage along with control (optimum) conditions. Grain yield (GY) and 19 other traits of agronomic importance (earliness, stemrelated traits, number of kernels, mass of 1000 grains, etc.) were recorded. All seedling traits under PEG-induced water stress showed the highest relationship with the stem and stem-related traits of adult plants. To study the correlation between stress tolerance in the seedling and reproductive stages, three stress indices (tolerance index (TOL), stress susceptibility index (SSI) and stress tolerance index (STI)) for the seedling traits and GY under pre-and post-anthesis drought stress were calculated, based on a mean trait value obtained under stress and the corresponding trait value under control conditions. The ranking of the genotypes based on TOL and STI from seedling traits was found in most cases to be significantly correlated with the ranking of genotypes based on TOL and STI from GY, respectively.
