Changes in Quality Components of Durum Wheat Genotypes Under Temperature Stress and Sufficient Rainfall Conditions During the Growth Period
(Publ House Bulgarian Acad Sci, 2024) Elis, Seval; Yildirim, Mehmet
A combination of genetic makeup and environmental factors determine the quality characteristics of durum wheat. Specifically, environmental stressors, such as extreme temperature fluctuations, can have a substantial impact on the productivity and quality of wheat crops. The effect of terminal temperature stress on yield and quality in durum wheat genotypes grown during 2019 and 2020 seasons was studied. These characteristics include thousand kernel weight, protein content, hectoliter weight, wet gluten content, Zeleny sedimentation value, and grain colour. The first year of the study was warmer than the second, resulting in decreased kernel weight, hectoliter weight, and gluten values, as well as increased protein content and Zeleny sedimentation values. This indicates that temperature stress leads to a higher protein content. The study also showed considerable variation in quality traits among genotypes, with certain genotypes demonstrating greater stability in specific quality traits. Genotype by environment interaction significantly affected grain weight, protein content, gluten content and Zeleny sedimentation. These data indicate that temperature stress plays an important role in determining the quality characteristics of durum wheat. Future studies should focus on mitigating the adverse effects of terminal temperature stress and improving the generation of genotypes with optimal quality traits.

The present study was undertaken to identify the best durum wheat genotypes suitable for the South-Eastern Anatolia Region of Turkey with desirable grain yield and quality. In the context, thirteen spring durum wheat genotypes were evaluated in four environmental condition of the target region in consecutive two growing seasons in the year 2013-14 and 2014-15. The stability and superiority of genotypes, and favorable testing environments were described by using ANOVA and GGE biplot analysis (genotype, genotype x environment). Genotype, environment and GEI (genotype x environment interaction) was found to be highly significant for multiple traits. The total variation of PCI (principles component) and PC2 was calculated 90% for ETI (environment trait interaction), 57.35 for GTI (genotype trait interaction), and 87.5% for GE interaction. The results of total variation of ETI was found higher than GTI and GEI. On the other hand, the biplot analysis showed that four megaenvironments occurred among ETI and three environments (E1, E2 and E3) correlated with different traits, while environments E4 did not correlated with any traits. The environment El was found the best for Grain yield, test weight, thousand kernel weight and starch content, E2 for L*, b*, SPAD, and E3 for zeleny sedimentation, protein content and wet gluten content. In the biplot analysis, the environments divided three sector based on traits. Among the genotypes, the genotype G8 was performed the best in all tested environments, while G9 was found the best based on all traits. The results of the study showed that GGE biplot analysis can be used as a good tool to identity of the most suitable environment in terms of all the characteristics as well as to identify the best genotypes for future breeding program.

Lentil is conventionally grown as a rain fed crop, mostly in the Middle East; it's a rich source of protein for human feeding. Yield, seed quality, adaptability and chalky spot syndrome of fifteen lentil genotypes and five lentil cultivars were evaluated in the South-Eastern Anatolia of Turkey. Yield and yield trails as well as seed quality such as protein content, seed rate with chalky spotted and germination rate for of all genotypes were varied significantly. Seed yield were varied from 1337 to 2142 kg/ha among the genotypes. While cultivar 'Sakar' produced the maximum yield and cultivar 'BM 848' produced the minimum seed yield. It was also revealed that genotypes 'ILL10975', 'FLIP2010-94L' and cultivar 'Sakar' was found the most sensitive to cold. Lentil crops with chalky spotted were detected in Adiyaman location and its rate ranged from 42% to 13%. Genotype x environment interaction was significant for seed yield and different stability parameters were computed for genotype adaptability. Ecovalance (W(2)i) and stability variance (sigma(2)i) were low value in genotypes ILL 3375 and Kafkas, but Firat 87 had high values.

Increasing nitrogen use efficiency in modern agriculture is important for obtaining high yields and reducing production costs and environmental pollution. Globally, price reduction and environmental concerns advocate a lower use of nitrogen (N) fertilizer for wheat (Triticum aestivum L.) crop, especially for wheat hybrids. The objective of this study was to assess combining ability at different N levels for agronomic traits and nitrogen use efficiency (NUE) via diallel analysis in wheat hybrids. Four spring wheat cultivars were used to produce a 4 x 4 full diallel cross with the reciprocals. Parents of various origins and their diallel F-2-hybrids were evaluated in field under 0, 120 and 240 kg ha(-1) N doses. The results showed that there was much genotypic variance among nitrogen doses for the NUE, grain yield, agronomic and quality traits. Significant genotypic differences in the yield, protein yield, protein content and NUE were identified among hybrids. General combining ability effect of parents for the grain yield and protein content, and specific combining ability effect of hybrids for the NUE and grain yield significantly changed depending on nitrogen levels. Both genetic and reciprocal effects showed interaction with nitrogen doses in determining the NUE of wheat. Because of the reciprocal x N interaction, the hybrids' reciprocal responses to increasing nitrogen levels revealed positive or negative changes in the yield and NUE characteristics. The winner among hybrids was identified for grain yield and grain nitrogen yield (GNY) at the optimum N level according to the GGE biplot analysis. Inqualab91 x Chils was found to be desirable for selecting NUE traits.

Stable and high yield varieties identification under various conditions prior to release as a variety is the main steps for breeding program. In order to exploit narrow and broad adaptability of genotypes and assess their effects, environment and GE interaction, 12 spring bread wheat genotypes were grown at four various experimental locations during 2013-14 and 2014-15 growing seasons. The stability and superiority of genotypes were identified by the AMMI (additive main effect and multiplicative interaction) and GGE (genotype, genotype x environment) biplot analysis. The AMMI analysis showed that the variance of genotype, environment and GE interaction were significant and the major treatment sum of squares were significantly affected by environments (85.47%), genotypes (8.51%) and GE interaction (6.07%). On the other hand, the first principal component axes (PCA 1) distributed to the complete interaction as 62.56%, and the second PCA 2 axes 37.44%. The GGE bi-plot analysis indicated that the total variation PC (principle component) was 83.09%, and PC1 was accounted as 63.69%, PC2 only 19.40%. The AMMI analysis showed that C11 was quite stable as well as the highest yielder among test genotypes, while C7 and C8 were unstable and low yielding across environments. The GGE biplot indicated that it was detected in two mega-environments, and the first mega-environment covered three environment (E1, E2 and E3), and the second mega-environment covered only E4. The genotypes C11 and C12 remained superior under ME I, while genotypes C1, C3 and C5 were for ME II. Among the genotypes, the genotype C1 may be recommended to be developed and released as an approved cultivar for being comparatively more stable and the highest yielder. Therefore the AMMI and GGE biplot models have an opportunity to determine the best genotypes under multiple environments considering on adaptability and stability concentrating on overall performance for screening superior genotypes.
