“…From statistical analyses utilizing this large dataset, the authors reported a much greater effect of environment on dough extensibility compared to genotype (Eagles et al, 2002). More recently, Živančev et al (2022) reported a significant effect ( p < .01) of environmental conditions due to crop year on dough extensibility for 18 wheat cultivars grown in Serbia over 3 years.…”

Background and Objectives: Safety aspects regarding free asparagine concentration in wheat arise because of its acrylamide formation potential in baked wheat products. Free asparagine concentration in wheat is affected by environment, genotype, and nitrogen and sulfur fertilization, which also affect wheat protein content and composition. Changing protein content and composition affects gluten strength, altering product quality. This study investigated how gluten strength was affected by environment, genotype, and fertilization treatments grown under commercially relevant conditions.Findings: Environment predominated in affecting dough extensibility and genotype primarily affected resistance to extension, with minimal effects from fertilization treatments. Differences in extensigraph parameters at two resting times segregated genotypes according to gluten strength. Conclusions: Factors affecting free asparagine accumulation in wheat also affect gluten strength. Genotype and environment require primary attention since they play an important role in both wheat safety and quality.Significance and Novelty: The lack of studies investigating the impact of factors affecting free asparagine concentration on the gluten strength of wheat has implications for the global wheat market. From a novel perspective on dough extensibility and resistance to extension, the effects of environment, genotype, and fertilization on the gluten strength of commercially important wheat varieties are considered in a food safety context.

Abstract. The aim of the study was to assess the size and stability of grain yield of a group of varieties grown in different conditions of the country. The study included a total of forty samples of winter common wheat, developed by Agronom breeding company. The field experiment was conducted in three typical grain production locations of the country: Dobrich, Trastenik and Straldja, in the period 2017-2019. All aspects of the interaction of varieties with environmental conditions were analyzed using two statistical programs PBSTAT and GEA-R. Through their application, 16 different parameters were calculated, through the ranks of which stability was assessed. The data obtained from the individual parameters were subjected to direct comparison with the modules of the programs GenStat 15, JMP 14 and GGE Biplot 6.3, which have a visual representation of the results for the level of yield and stability of each cultivar. The stability of only the varieties with higher yield than the check cultivar was monitored. Their stability was monitored and measured through all software products before a conclusion was made about its level. The share of genotype and its interaction with environment was only about 20% of the total variation. The conditions in the individual locations have a significant impact on the yield performance, which causes a strong change in the yield in the individual varieties. It causes a drastic change in the rank of the yield by locations. Against the background of strong G x E interaction, only six varieties have been identified: ABC Aldo, ABC Grosso, ABC Lombardya, ABC Klausius, ABC Zigmund and ABC Navo, whose average yields were proven to be higher than those of the check variety LG Avenue. Their high productive potential was realized to a degree that guarantees high stability in changing conditions of the used regions. Current statistical models were effective in quickly and efficiently determining all possible levels of combination between genotype yield and stability. The newly created varieties showed higher stability than the already established ones, as their productivity was at a much higher level. Breeding, accompanied by ecological tests of many advanced lines, shows that it was possible to combine high yields with relatively high stability with enough varieties for successful zoning throughout the country.

The goal of this research is to test breeding material of different geographical origin, and material that is adapted to different agro-climatic regions. This research examines how different wheat genotypes behave in the climatic conditions of the Pannonian Plain, where environmental stress occur more and more frequently. Fifteen divergent wheat genotypes were evaluated for grain yield, heading time and yield components (spike length, grain weight per spike and plant height) across seasons 2017/2018, 2018/2019 and 2019/2020. By applying the ANOVA model, significant differences between tested traits were recorded among the analyzed genotypes. Among the genotypes there was a variability that ranged widely for all tested traits. The coefficient of variation ranged from 5.48% for plant height to 41.03% for grain weight per spike. Correlation analysis showed strong positive relationships between grain yield and grain weight per spike (r=0.87), as well as between plant height and heading time (r=0.65). Principal Component Analysis (PCA) was also applied in order to determine the differences between wheat genotypes. This yield marker study, which was carried out in the Western Balkans, could be very valuable in providing breeders with the information they need to evaluate their breeding programs.
