“…Other crop quality traits include kernel weight, often measured as Thousand Kernel Weight (TKW), and specific weight, often measured as Hectoliter Weight (HLW). These parameters are important indicators of the physical quality of grains and are commonly recognized as indicators of potential flour yield by the industry (Marconi et al, 1999;Sirat, 2023). Additionally, the test weight has (together with protein content) a direct influence on the price the farmer receives for his wheat grains (swissgranum, 2023a).…”

In the current quest for a more sustainable, environment-friendly agriculture, variety mixtures are often suggested as a practical option to increase the stability of food production systems. Their effects on yield have been extensively researched, yet clear conclusions remain elusive, notably in terms of mechanistic processes and optimal variety combinations. Furthermore, in the case of wheat, yield is not the only component in the equation: grain quality is crucial for the bread value chain, yet the effects of variety mixtures on wheat quality and its stability have rarely been investigated. To that end, we conducted a multi-year, multi-site wheat variety mixture experiment investigating the role of variety mixtures on the performance and stability of five traits linked to grain yield and quality, and the mechanisms underlying these effects. Eight varieties were grown in pure stands and 2-variety mixtures, following a full diallel design. We considered the responses of grain yield, protein content, thousand kernel weight, hectoliter weight, and Zeleny sedimentation value. Results showed that mixtures generally outperformed pure stands in terms of global performance and stability for the 5 parameters. We particularly noticed an increase in quality stability and in Zeleny sedimentation value in mixtures, showing the potential of mixtures to improve crop quality. Moreover, we highlighted the important role of light interception for increased mixtures benefits. A more detailed investigation into individual mixture performances led us to some practical rules for optimal variety combinations: we advise combining varieties with similar heights and phenologies but different tillering abilities and yield potential. This study thus shows that variety mixtures represent a promising solution to sustainably increase the stability of wheat yield and quality. With practical recommendations, our results could benefit farmers but also processors and bakers, and promote the adoption of wheat variety mixtures.

The current study aimed to determine and compare the grain yield, some quality characteristics and high-molecular-weight glutenin subunits (HMW-GS) of bread wheat cultivars cultivated in several agro-ecological regions using a total of 46 registered bread wheat cultivars in the 2016–2017 and 2017–2018 growing seasons. The results determined that the environment had the largest share in the total variation (Genotype + Environment + Genotype×Environment Interaction). The Mediterranean region had the highest average grain yield with 8137 kg ha− 1, while the Central Anatolia region (under the rainfed conditions) had the lowest average with 4260 kg ha− 1. The average thousand kernel weight of the cultivars was 35.3–39.9 g, test weight 77.2–79.2 kg hL− 1, protein content 13.4–14.7%, Zeleny sedimentation 39.2–53.3 mL, and alveograph energy value varied between 191.2-276.4 10− 4 J. Regarding the HMW-GS, 18 of the 46 cultivars scored 10, and one scored 5. The highest mean protein content and alveograph energy value was determined in cultivars with 9 Glu-1 score. In Zeleny sedimentation, cultivars with 10 Glu-1 score showed the highest mean value. The most common subunits in loci; it is 2* in Glu-A1, 7 + 8 and 7 + 9 in Glu-B1, and 5 + 10 in Glu-D1. The fact that registered cultivars predominantly carry these subunits at Glu-1 loci, which could be the result of yield and quality-oriented selection in the breeding process. It was concluded that high quality new varieties could be developed by HMW-GS oriented crosses and selections in wheat breeding programs.
