“…Although drought stress during the booting stage inhibited spikelet development and reduced the number of spikelets, we established that the effects on the NIS were non-significant. These findings are consistent with those presented by Tatar et al (2020), who observed drought-induced reductions in spike and spikelet numbers during the stem elongation stage. The lower NGS in wheat exposed to the low-water treatment can be assumed to reflect insufficient spikelet development.…”

“…Furthermore, the findings of some studies have indicated that the concentration of grain proteins initially increases and subsequently declines in response to an increase in drought stress degree (Silva et al, 2020;Yan et al, 2020). In the present study, we detected reductions in protein concentrations in the grains of wheat subjected to the low-water treatment, which is consistent with the findings of Meng et al (2016), but contrasts with observations of Silva et al (2020); Tatar et al (2020), andYan et al (2020). We suspect that these discrepant findings could reflect differences in the respective intensities of the applied stresses.…”

“…GPC, expressed as the ratio of protein weight to dry matter weight, is determined by the characteristics of both grain filling and grain N accumulation. In this regard, given that grain protein content is diluted by non-nitrogenous compounds as grain yield increases, yield is negatively correlated with protein concentration ( Moral et al., 2007 ; Graziano et al., 2019 ; Tatar et al., 2020 ; Santis et al., 2021 ). However, the relationship between grain yield and GPC changes in response to different water treatments ( Meng et al., 2016 ).…”

In China, water-saving irrigation is playing important roles in ensuring food security, and improving wheat quality. A barrel experiment was conducted with three winter wheat (Triticum aestivum L.) genotypes and two irrigation pattens to examine the effects of regulated deficit irrigation (RDI) on wheat grain yield, water-use efficiency (WUE), and grain quality. In order to accurately control the soil water content, wheat was planted in the iron barrels set under a rainproof shelter, and the soil water content in the iron barrel was controlled by gravity method. The mechanisms whereby water management influences the end-use functional properties of wheat grain were also investigated. The results revealed that RDI improved the end-use functional properties of wheat and WUE, without significant yield loss (less than 3%). Moderate water deficit (60% to 65% field capacity) before jointing and during the late grain-filling stage combined with a slight water deficit (65% to 70% field capacity) from jointing to booting increased grain quality and WUE. The observed non-significant reduction in wheat yield associated with RDI may be attributed to higher rate of photosynthesis during the early stage of grain development and higher rate of transfer of carbohydrates from vegetative organs to grains during the later stage. By triggering an earlier rapid transfer of nitrogen deposited in vegetative organs, RDI enhances grain nitrogen content, which in turn could enhance dough elasticity, given the positive correlation between grain nitrogen content and dough midline peak value. Our results also indicate that the effects of RDI on grain quality are genotype dependent. Therefore, the grain end-use quality of some specific wheat genotypes may be enhanced without incurring yield loss by an optimal water management.

“…Drought is one of the most important environmental factors and severely impact crop growth, yield and quality ( Krasensky and Jonak, 2012 ; Zhang et al, 2014 ; Tatar et al, 2020 ). After long terms of evolution, plants have developed various strategies to cope with deleterious effects of drought, which deserves in-depth investigation.…”

Wheat as a staple food crop is enduring ever-frequent intermittent and changing drought with the climate change. It is of great significance to highlight the adaptive approaches under such variable conditions at multiple levels to provide a comprehensive understanding of drought tolerance and facilitate the genetic breeding of wheat. Therefore, three wheat lines with different drought tolerance (drought-tolerant mutant Mu > common wheat CK > drought susceptible mutant mu) were analyzed under moderate and severe drought stresses as well as rehydration. Samples were subjected to transcriptomic and metabolomic profiling in combination with physiological and biochemical determination. The moderate drought stress rendered 198 and 115 differentially expressed metabolites (DEMs) in CK and Mu, respectively. The severe drought stress rendered 166, 151 and 137 DEMs in CK, Mu and mu, respectively. The rehydration rendered 150 and 127 DEMs in CK and Mu. 12,557 and 10,402 differentially expressed genes (DEGs) were identified for CK and Mu under moderate drought stress, respectively. 9,893, 7,924, and 9,387 DEGs were identified for CK, Mu, and mu under severe drought stress, respectively. 13,874 and 14,839 were identified in CK and Mu under rehydration, respectively. Metabolomics results showed that amino acid was the most differentially expressed metabolites, followed by phenolic acids. Flavonoids played an important role in drought tolerance. Most enriched pathways under drought included biosynthesis of secondary metabolites, metabolic pathways and photosynthesis. Metabolites and genes involved in osmotic regulation, antioxidase activities, and ABA signaling were more enriched in Mu than in CK and mu. Various drought-responsive genes and metabolites in Mu showed different trends with those in CK and mu. Increased amino acids biosynthetic capability and ROS scavenging ability resulted from higher antioxidase activities and increased flavonoids may be the mechanisms underlying the drought tolerance characteristic of Mu. Recovery from reversible ROS damage and rapid amino acid biosynthesis may contribute to the rapid recovery of Mu. The present study provides new insights for mechanisms of wheat under complex drought conditions.

“…Development of cultivars characterised by a high and stable GY represents one of the main goals in winter wheat breeding programs. Moreover, different winter wheat cultivars showed a contrasting performance across different environments due to a significant GEI (Hristov et al, 2010b;Tatar et al, 2020). Knowledge about GEI is important for crop breeders, since GEI complicates the selection of superior genotypes affecting breeding strategies, multi-environmental testing, time, and the allocation of resources (de Leon et al, 2016).…”

The aim of this study was to analyse the changes in winter wheat (Triticum aestivum L.) grain yield and stability during the last century and to identify meteorological variables related to the cultivar performance in many-years research. A historical set of 47 winter wheat cultivars widely grown in the Pannonian Plain region during the period between 1930 and 2013 was studied. Field experiments with 47 winter wheat cultivars were conducted during ten growing seasons. Grain yield, main agronomic traits, protein content, and Zeleny sedimentation test were studied. The selected cultivars were widely grown and/or extensively used in breeding activities in Serbia and surrounding countries. The obtained results varied significantly across the growing seasons and breeding periods. The grain yield was closely related to winter wheat genetic gain. The genetic progress of grain yield was 48 kg ha -1 per year of cultivar release. Precipitation during winter, stem elongation, and mid and late grain filling stages were highly associated with the grain yield and genetic gain. Differences among the breeding periods were significant for the plant height. The cultivars of the 1st breeding period were the highest with an average plant height of 109 cm. The lowest plant height was recorded in the cultivars of the 5th and 6th breeding periods: 78.5 and 80.5 cm, respectively. Among the growing seasons, the average plant height ranged from 69.5 to 98.6 cm. The hectolitre weight varied from 77.6 to 79.6 kg hl -1 . The thousand grain weight showed a small variation and ranged from 40.1 to 41.9 g. The protein content significantly varied among the breeding periods and growing seasons. Modern cultivars of the 6th (12.4%) and the 4th (12.5%) breeding periods had the lowest protein content, while the highest protein content (14.0%) was recorded in the initial cultivars of the 1st breeding period. The modern winter wheat cultivars showed a higher grain yield potential and stability than older ones. Therefore, the improvement of cultivars stability across different environmental conditions should represent a notable strategy for further increase of the winter wheat grain yield potential.
