“…The main effects of genotype, environment and G × E interaction were very significant (P < 0.001) (Table 6). The magnitude of the SSGE was 3.59 times more than that for genotype effect, demonstrating there were considerable deferential response among the genotypes to change of environment and the differential discriminating ability of the test environment (Shukla et al 2015;Heidari et al 2017;Bavandpori et al 2018;Tekdal & Kendal 2018;Mekonnen et al 2020). The value of the GEI is mostly due to variations in environmental conditions from supplementary irrigated to rainfed and from year to year.…”

“…The AMMI model by puncturing genotypes and environments on the biplot, identifies the position of the genotypes relative to each other and the studied environments (Elakhdar et al 2017). Mohammadi et al (2015), Ajay et al (2020), Khan et al (2020), Lozada & Carter (2020), Mekonnen et al (2020), Mohammadi et al (2020) and Verma & Singh (2021) by examining the stability of wheat genotypes reported that the AMMI method with high fitting power, is more suitable than other methods for determining genotypes with general and specific adaptability for different locations. Ahakpaz et al (2021) by examining 18 rainfed barley genotypes for three cropping years in cold rainfed regions of Iran, reported that the effects of G, E and GEI on grain yield were significant.…”

In rainfed areas, due to variable environmental factors, improving the yield stability of the introduced cultivars along with increasing yield should be considered. The main aim of this study is to obtain high-yield wheat genotypes that are stable and adaptable to cold climatic conditions in Iran. For this purpose, 25 wheat genotypes were evaluated in a randomized complete blocks design with three replications during three cropping seasons (2013-2016) under supplementary irrigation and rainfed conditions. PBSTAT-GE software was used for genotype × environment interaction (GEI) analysis and comprehensive sustainability analysis. The results showed that G5, G14, G16 and G18 genotypes had good stability and general adaptation based on parametric and non-parametric stability statistics. Combined analysis of variance based on the Additive Main Effect and Multiplicative Interaction (AMMI) model showed that GEI is significant in the term of grain yield. Also, the ratios between the sum of squares G, GE and IPC1 showed that the AMMI is suitable for data analysis. GGE biplot analysis identified five mega-environments (MEs), in which ME I including E1, E2, E3, E4, E5, E6, and G7, G5, G14, G13, G16, G18, G20 being the superior ME I genotypes. According to AMMI and GGE biplote stability methods, lines G20, G18, G13, G16, G14 and Saein cultivar (G5) can be considered as desirable genetic resources in wheat production programs under variable environments in Iran, due to having the appropriate combination of yield and stability.

“…Pigmented barley ( Hordeum vulgare ) and wheat ( Triticum aestivum and Triticum turgidum ) are gaining attention due to their rich phenolic content, health implications and various food applications [ 8 , 9 , 10 , 11 , 12 , 13 ]. Hordeum vulgare is a common hull-less barley that is used in making beverages and other cereal based products [ 8 ].…”

“…Likewise, pigmented varieties of the common bread wheat ( Triticum aestivum ) offer great nutritional value due to phenolic content [ 8 ]. The blue coloured variety is pigmented in the aleurone layer and has been the subject of studies focused on the antioxidant activity of pigmented wheats and selective breeding of new varieties [ 11 , 12 ]. On the other hand, Triticum turgidum is a durum wheat originating from Ethiopia [ 12 ].…”

Polyphenols in pigmented cereals are believed to enhance health outcomes through their antioxidant properties. This study aimed to characterise polyphenols from Hordeum vulgare (purple barley), Triticum turgidum (purple wheat) and Triticum aestivum (blue wheat) in order to evaluate their bioaccessibility and antioxidant activity. An ultra-high performance liquid chromatography mass spectrometry coupled with an online 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) system was used to identify the polyphenols and quantify their relative antioxidant levels. Simulated gastrointestinal digestion of the cereals allowed for the assessment of polyphenol bioaccessibility using benchtop assays. Between cereals, the bioaccessible phenolic content was similar following digestion, but the antioxidant activity was significantly different (purple barley > purple wheat > blue wheat; p < 0.01). Among the polyphenols identified, flavan-3-ols and anthocyanins were the least bioaccessible whereas flavones were the most bioaccessible after digestion. This study demonstrated that these pigmented cereal varieties are sources of bioaccessible polyphenols with antioxidant activity. These findings may aid in utilising these pigmented grains for the future design and development of novel functional food products with enhanced health properties.

The testing of durum wheat (Triticum turgidum subsp. durum) varieties in different irrigated environments is critical for determining the stability of their performance and adaptation. In this study, 12 popular and newly developed durum wheat varieties were examined in eight irrigated locations with the purpose of investigating genotype–environment interaction and their effect on Ethiopian tetraploid wheat yield stability across diverse environments. The field experiment has two replications with a randomized complete block design. Multivariate (analysis of variance, additive main effect and multiplicative interaction [AMMI], and genetics, genetics × environment [GGE] biplot) and univariate (bi [regression coefficient], S2d [deviation from regression], σi2 [Shukla's stability variance], Wi2 [Wricke's ecovalence], YSi [yield stability statistic], and CVi [coefficient of variance]) analysis methods were used to identify stable varieties. The AMMI analysis showed that the genetic × environmental interaction was highly significant (p > 0.01), while the genotype and environment variation were not significant. The first two principal component axes (IPCA1 and IPCA2) were highly significant (p > 0.01) and contributed 79% of the total GE interaction. Univariate statistical models indicate that Bulala is a stable, high‐yielding variety that can adapt to various environments. GGE biplot analysis revealed that the eight test environments were clustered into three mega‐environments, ranked Bulala as the most stable variety across diverse environments. The results of the combined mean analysis, multivariate and univariate models revealed that Bulala is a high yielder (3.46 tons ha−1) and stable variety across all test environments, while Mukiye variety has a high yield (3.43 tons ha−1) but is not as stable or adaptive to multiple locations. As a result, Bulala was recommended for further demonstration and popularization in test locations and places with similar agroecologies under irrigation.
