The phytic acid (PA), inorganic phosphorus (Pi), yellow pigment (YP), water soluble phenolics (WSPH) and free protein sulfhydryl groups (PSH) of 15 Triticum aestivum and 15 Triticum durum wheats grown at six different environments were evaluated for variability, intra- and inter- relations with agronomic traits. The most variable properties in bread wheat were YP and WSPH with coefficients of variation (CV) amounting to 14.59% and 14.10%, respectively, while in durum wheat those were PSH and YP with CV of 17.59% and 15.02%, respectively. PA in durum wheat showed the least variability (CV 3.61%). Among others, positive associations were obtained between WSPH and YP in bread and durum wheat, YP and PSH, WSPH and PSH, yield (YLD) and WSPH, YLD and PSH in durum wheat, while negative associations were recorded for PA and YP, PA and WSPH, YLD and antioxidants (YP and WSPH) in bread wheat, PA and antioxidants, PA and YLD in durum wheat.

Antioxidants prevent oxidative stress and exert positive health effects. However, phytic acid among them decreases micronutrients absorption, representing also antinutrient to human and non-ruminant animals. Fifteen bread wheat (Triticum aestivum L.) and 15 durum wheat (Triticum durum Desf.) genotypes were evaluated across six environments to determine contents of phytic acid (PA), inorganic P (Pi), total yellow pigment, total soluble phenolic compounds, free protein sulfhydryl groups (PSH), and also phytic acid P/Pi (Pp/Pi). The objective of this study was to quantify, for each trait the effects of environment, genotype, and their interaction; and the influence of climatic factors on the Genotype × Environment interaction (GEI) by the use of the factorial regression. GEI (P < 0.001) prevailed as source of variation over genotype (P < 0.001) in determining PA content in bread and durum wheat (44.3% and 34.7% of sum of squares-SS, respectively), PSH content in bread and durum w...
Effects of Environment and Genotype on Phenolic Acids in Wheat in the HEALTHGRAIN Diversity Screen †
Journal of Agricultural and Food Chemistry, 2010
Phenolic acid content and composition have been determined in 26 wheat genotypes grown in Hungary over three consecutive years and at three additional locations (France, United Kingdom, and Poland) during the third year. Fractions comprising free, soluble conjugated, and bound phenolic acids were analyzed using HPLC with measurements being made for individual phenolic acids in each fraction. Statistically significant differences in phenolic acid content occurred across the different growing locations with the average total phenolic acid content being highest in the genotypes grown in Hungary. The growth year in Hungary also had a large impact, especially on the free and conjugated phenolic acid contents. Certain genotypes were more resistant to environmental impacts than others. Of the genotypes with high levels of total phenolic acids, Lynx, Riband, Tommi, and Cadenza were most stable with respect to their total contents, whereas Valoris, Herzog, and Malacca, also high in phenolic acid content, were least stable. Of the three fractions analyzed, the free and conjugated phenolic acids were most variable and were also susceptible to the effect of environment, whereas bound phenolic acids, which comprised the greatest proportion of the total phenolic acids, were the most stable.
Genotypic and environmental variation in protein and antioxidants content of bread and durum wheat
Romanian agricultural research
The objective of this study was to determine effects of the genotype, environment and genotype byenvironment interaction on the several quality and antioxidant-related traits of six bread and durum wheat genotypes bred at the Maize Research Institute, Serbia. 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 side, 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. Higher temperatures and lower precipitations resulted in larger kernels, higher protein and gluten content, but negatively influenced antioxidant properties, total phenolics and lipid so...

The health-promoting effects of whole-grain wheat likely derive from phenolic compounds and other antioxidants that also make wheat a potential source of functional food ingredients. The objective of this study was to determine the effects of genotype and growing environment on the phenolic contents and antioxidant activities of alcohol-soluble extracts from commercial wheat cultivars. Total phenolic contents (TPCs), antioxidant activities (AOAs), and concentrations of six phenolic acids were measured in six red-and white-grained hard spring wheat genotypes grown at four diverse locations in Western Canada during the 2003 crop year. There were significant differences among genotypes and environments for TPC, AOA, and concentrations of all the phenolic acids measured. The predominant indicators of antioxidant potential, i.e., TPC, AOA, and ferulic acid (FA) concentration were highly intercorrelated (r > 0.72). For these indices, the Canada Western (CW) Red Spring wheat cultivars Neepawa and AC Elsa had the highest levels, whereas an analogous CW hard white spring wheat cultivar, AC Snowbird, had the lowest levels. Grain color did not appear to be a factor in the expression of antioxidant-related parameters. For both TPC and AOA, as well as for vanillic acid, syringic acid, and ferulic acid, environmental effects were considerably larger than genotype effects. Neither growing temperature nor rainfall from anthesis to maturity appeared to be related to the environmental variation that was observed. Genotype × environment interaction was small for all parameters compared with genotype and location effects and was significant only for TPC. Genotype variation for antioxidant properties indicates that it would be possible to select for these quantitative traits in a breeding program. However, the significant environmental variation observed would delay and/or complicate this process.
Genotypic and environmental variation of bread and durum wheat proteins and antioxidant compounds
The objective of this study was to determine effects of the genotype, environment and genotype by environment interaction on the several quality and antioxidant-related traits of six bread and durum wheat genotypes bred at the Maize Research Institute, Serbia. 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. 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.

BACKGROUND: We investigated three old wheats (Triticum dicoccum, Triticum durum, Triticum spelta) for effects of organic and conventional cultivation under equivalent nitrogen fertilisation (100 kg ha-1) on antioxidant content and composition, and on quality traits. RESULTS: Compared to conventional cultivation, organic cultivation had positive effects on test weight, while grain quality traits of protein content, gluten content and sodium dodecyl sulphate microsedimentation volume were 19.2%, 9.3% and 22.7% lower, respectively. Despite lower protein content with organic cultivation, this was still high (147 g kg-1); thus with adequate organic N fertilisation, the quality traits related to the technological properties of flour were maintained. Total phenolic content (TPC) was significantly higher for organic versus conventional cultivation, although free and bound phenolic acids were not significantly different. With discriminant analysis, only durum wheat differentiated the qualitative and compositional traits according to cultivation system. Separation of organic versus conventional cultivation in durum wheat and emmer was strongly affected by antioxidants (antioxidant capacity, TPC, yellow pigment content), dietary fibre, protein content and test weight. CONCLUSIONS: With adequate organic nitrogen fertilisation, protein and gluten contents remain high enough for good quality pasta. However, except for TPC, organic cultivation did not affect phenolic acids profile and antioxidant activity.

Cereal Chem. 91(4):310-317 In cereals, phenolic acid (PA) content and total antioxidant capacity (TAC) may have a wide range of variability, probably because of several factors influencing the occurrence of grain antioxidants, which include genotype, environment, and their possible interactions. However, only a few studies have investigated the influence of these factors on durum wheat. In the present study, we investigated the impact of the genetic and environmental factors on the profile and content of PAs occurring as soluble free, soluble conjugated, and insoluble bound compounds, as well as on the TAC level, in three genotypes of durum wheat grown in three different Italian agroclimatic areas during two crop years. The results show that genotype, environment, and crop year have highly significant effects on TAC levels and on PA contents. In particular, TAC and free PAs are most influenced by year, whereas conjugated and bound PAs are most influenced by environment × year and genotype, respectively. Therefore, it is evidenced that genetic and environmental factors affect the antioxidant activity and the content of the three forms of PAs in durum wheat to different extents.

One of the most significant factors affecting resistance to fungal diseases in winter wheat genotypes is the content of phenolic compounds. A total of 100 winter wheat cultivars were investigated. The contents of five phenolic acids: ferulic, vanillic, syringic, vanillin, p-coumaricand free phenolic acids (FPA) were determined. Considerable variation was found both within tested cultivars. Among the investigated acids the greatest amounts were recorded for ferulic acid and its mean concentration was 975 µg g -1 , p-coumaric acid was characterised by a lower mean concentration (52 µg g -1 ), while the lowest concentration was recorded for vanillin, amounting to 5 µg g -1 . Ferulic acid state 92.4% of total phenolic acids. Significant differences in content of ferulic acids between genotypes were observed. The group of winter wheats coming from different European countries was characterized by high variation in the contents of ferulic acid, ranging from 320 to 3103 µg g -1 . No signif...
