“…Although grain yield is always paramount, quality has been systematically and thoroughly investigated (De Santis et al, 2017, Liu et al, 2022. The influence of environments on quality has been studied through a number of its different team-related indexes (Bornhofen et al, 2017;Penchev et al, 2019;Öztürk, 2022). The strength of the effects of the conditions (E), of the genotype (G) and the interaction between them (GE) for each index have different shares (Alemu and Gerenfes, 2021;Kyratzis et al, 2022.…”

The influence of the environment on the basic indexes of the grain as Wet Gluten Content index (WGC), Gluten Index (GI), and Zeleny sedimentation index (Zeleny) in wheat without a doubt is significant (Karaman, 2020;Bosi et al, 2022;Öztürk, 2022). This makes the evaluation of varieties by grain quality very difficult, because each of them shows different performance, despite the existing positive correlations between them (Öztürk, 2022;.…”

“…Second, is the variation of a variety as measured by one of the quality indexes analogous to that of other ones? Divergence in variety stability measured by different indexes is more the rule than the exception (Stoeva, 2012;Öztürk, 2022). Discrepancy in the evaluation of the stability of cultivars by specific indexes is common, and yet there is progress in breeding (Mirosavljević et al, 2020).…”

“…High-yielding stables, what level of quality could they have -"low" "medium" or even "high"? Complex yield-quality relationships are generally negative but may change substantially by genotype x environment interaction (Öztürk, 2022;. This is an indication the combination of the two aspects of the grain -yield and quality is possible, but at compromise levels of each of them to have progressed in terms of quality as well (Bosi et al, 2022;Ilin et al, 2022).…”

The study was conducted to evaluate the stability of common wheat varieties in four locations with proven different environmental conditions. Three indexes of grain quality were studied: wet gluten content, (WGC); gluten index of grain (GI) and grain sedimentation value (Zeleny). The stability of varieties has been evaluated by many parameters that reflect different aspects of the complete picture for it. The indexes studied are strongly influenced by environmental conditions. The most genetically stable among them is the gluten index (GI), where the genotype has a decisive role of about 70% of the variation, and the most unstable is the wet gluten content (WGC), with only 17% of the effect. As a result of reliable GE, the ranking of the varieties according to the performance of each of the indexes is different in the individual locations. The ranking of varieties in terms of stability according to the ranks of each of the parameters is very different. Even a visual representation of the results, which clears the picture to the maximum extent, shows a different set of stable varieties in each of the quality indexes. Only a few of the varieties (G2, G6, G9, G13, G18, G20, G22) have a good balance between the size and stability of all quality parameters, with a moderate compromise with the grain yield level. The assessment of the stability of the variety in terms of quality can be made according to any of the indexes used. The stability of the variety depends to a large extent on the effect of the environment, which must be considered when selecting a specific index for assessment. The most suitable for this purpose is the gluten index (GI), where the influence of genotype is the strongest, with a significant GE interaction accounting for 25% of all variation. The stability of the variety does not depend on the magnitude of the quality indexes. Stable can be both quality (G2, G6) and varieties with very low grain quality (G18, G20, G22). Stability of quality, at high levels of indexes, is associated with low grain yield and vice versa. From this point of view, combining high yield stability and grain quality at the highest possible levels is a very rare exception (G2, G9).

The purpose of the study was to determine the stability of winter wheat (Triticum aestivum L.) cultivars according to the quality indices: deformation energy (W), alveograph P (dough tenacity) to L (dough extensibility) ratio (P:L), and dough extensibility (swelling) index (IE). The data were collected from four locations with different climatic conditions, in three consecutive years. The evaluation of the cultivar stability was made for each index using the statistical software PBSTAT specialised for this purpose. The information from its 16 different parameters is combined into a parameter stab16, by which the cultivars are compared for stability. The indices studied are influenced to varying degrees by the environmental (E) conditions. As a result of a reliable genotype and environment interaction (G × E), the stability ranking of cultivars according to the ranks of each of the parameters was very different. The level of stability of the cultivar in the studied different aspects of its grain quality is related to different levels of the indices. For the IE index, many of the studied cultivars are unstable in performance, which excludes its use for stability assessment. A limited number of cultivars combine a high and stable quality in different environmental conditions (c6 and c7). The W and P:L indices can be used independently to evaluate the stability of the cultivar as an additional characteristic of its quality. The estimation of cultivar stability by averaging the ranks of parameters (stab16) proved to be an effective approach due to its proven high and positive correlations with most of the 16 parameters. The applied analogical approach for the simultaneous assessment of quality stability does not provide correct information for the individual cultivar due to a significant discrepancy when comparing the information from each of the three indices.

The significant genotype by environment interaction is a major matter for wheat breeding research. The study was carried out for seven growing season (between 2010-2011 and 2016-2017) in the Edirne location in the Trakya region, Türkiye. Each year was considered as a single environment. In the study, a regional yield trial of 25 genotypes, 5 of which were standard cultivars were evaluated across seven environments. The experiments were arranged in a randomized complete block design (RCBD) with four replications. The characters such as yield, days to heading, plant height, thousand kernel weight, hectoliter weight, protein ratio, wet gluten content, gluten index, grain hardness and sedimentation value were investigated in the study. The result of the variance analysis (ANOVA) demonstrated considerable differences (p
