Climate change imposes many environmental stresses out of which drought stress is a major concern that significantly restricts crop production in arid and semi-arid regions. The negative impact on grain quality caused by drought stress is responsible for reduced grain yield and quality. Many previous studies aimed to understand the tolerance level of wheat varieties, but studies on grain quality traits assessment were less. Therefore, the aim of the present investigation was to study some grain quality traits and to determine how drought stress affected these parameters. Experiments with two wheat varieties viz. WH 1105 and WH 1025 were conducted in microplots with RBD design in open fields. Grains were selected after harvest of the crop and were used to evaluate sedimentation value, β carotene, crude fibre, total sugars and starch. Sedimentation values (ml) were increased more in WH 1025 (6.9 per cent) than WH 1105 (3.8 per cent). Beta carotene content (µg g-1 DW), crude fibre (%), total sugar (%) and starch (%) contents were decreased in both wheat varieties and more decrease was observed in WH 1105 than WH 1025 under drought condition than irrigated condition. The study revealed that quality traits of WH 1105 were much affected than WH 1025 under drought stress.

In Mediterranean environments the adoption of Conservation Agriculture (CA) would allow growers to achieve environmental, agronomic and economic sustainability. We investigated the effect of different combination of crop establishment treatments and crop sequence (conventional tillage (CT) and durum wheat monocropping (WW); conventional tillage (CT) and durum wheat following faba beans (WF); zero tillage (ZT) and durum wheat monocropping (WW); zero tillage (ZF) and durum wheat following faba beans (WF) on yield, grain quality traits as well as on disease incidence and severity in durum wheat (var. Saragolla). The results of two years of data of a long-term experiment (seven-year experiment; split-plot design) are discussed. The CA approach (ZT + WF), which always induced the highest grain yields (6.1 t ha−1 and 3.3 t ha−1 in 2016 and 2017) thanks to an increased number of spikes m−2 (296 vs. 269 and 303 vs. 287 spikes m−2 in 2016 and 2017, respectively) as well as a more pronounced ear length, demonstrated significantly positive influences in terms of grain quality. It promoted grain protein accumulation (12.1% for ZT + WF vs. 11.4% for ZT + WW and 12.4% for ZT + WF vs. 10.6% for ZT + WW in 2016 and 2017) and improved the gluten quality (in terms of sodium dodecyl sulphate (SDS) sedimentation test) and colour of the grain. The abundance of crop residues determined a higher incidence and severity of Zymoseptoria tritici leaf symptoms under the CA system; nevertheless, the late appearance of infection was the main reason for not affecting yield and quality traits. The presence of faba beans (WF) in the rotation significantly reduced leaf symptoms in Z. tritici.

The current paper has presented the study results of grain quality and pasta properties of the new and promising winter durum wheat varieties developed in the FSBSI “Agricultural Research Center “Donskoy” in 2016–2018. The purpose of the study was to evaluate winter durum wheat varieties according to such traits as grain quality and pasta properties to identify the best genotypes and recommend them for use in the breeding process and wider introduction into production. There have been identified the varieties “Yubilyarka” (96%), “Kristella” (94%), “Lakomka” (92%), “Diona” and “Yantarina” (91%) with maximum values of general hardness. All studied genotypes have formed the nature weight of grain corresponding to a first quality class (from 786–814 g/l). There have been identified the varieties “Kristella” (13.9%), “Donchanka” (13.8%), “Diona” (14.0%), “Yakhont” (14.0%), “Yubilyarka” (13.6%), “Yantarina” (13.7%), “Uslada” (13.6%), “Zoloto Dona” (13.6%), “Solntsedar” (13.9%) and “Almaz Dona” (13.5%) with protein percentage in grain corresponding to a first quality class. As a result of the study, it was found that all the studied varieties had good rheological properties of gluten and formed a DCI from 80 units (the variety “Eyrena”) to 102 units (the variety “Donchanka”) and belonged to the 2-nd group. The varieties “Diona”, “Eyrena”, “Yakhont”, “Yantarina” and “Solntsedar” had high rheological properties of dough. There have been identified the genotypes of the varieties “Donchanka” (613 μg/%), “Solntsedar” (626 μg/%) and “Almaz Dona” (630 μg/%) with the maximum concentration of carotenoid pigments, which could be used as sources to improve the trait “carotenoid content”. Throughout the years of study, the varieties were characterized by high indices of dry pasta color (4–5 points). According to a brittle strength of dry pasta there have been identified the varieties “Kristella” (775 g), “Donchanka” (774 g), “Diona” (757 g), “Yantarina” (782 g), “Solntsedar” (766 g) and “Dinas” (769 g) with the best indices of the trait. The varieties identified both by a single and by a set of traits characterizing grain quality of winter durum wheat and its final products, can be used in the breeding process as an adaptive initial material. The introduction of the best varieties into production will partly solve the problem of deficiency of high-quality durum wheat in the south of Russia.

Abstract The aim of this research was: (1) to assess the effect of an integrated cultivation system of native durum wheat (6 variants), differentiated by a nitrogen fertilization dose (0, 80, 120 kg.ha-1) and growth regulator use (Medax 350 SC, with growth regulator - GR, without growth regulator - WGR) on changes in selected quality parameters (protein, lipid, and starch contents; hardness; color) and electrical parameters (conductive - Z and capacitive - Cp, Cs) of the grain; and (2) to determine the correlations between the examined quality traits and electrical properties of the grain to indicate the possibility of using a non-invasive electrical method to assess grain quality. The grain of durum wheat cultivated in the six variants tested differed mainly in the starch and lipid contents, which indicates the feasibility of tailored optimization of grain production. The highest contents of starch and total lipids, and the highest grain hardness were obtained in the cultivation variants GR+0N and WGR+0N, whereas the highest protein content - upon wheat fertilization with 120N. The study demonstrated a different strength of the correlations between the tested parameters depending on the cultivation method (WGR-GR; N: 0, 80, 120 kg.ha-1). In the WGR+0N variant (environmentally friendly), the strongest correlation between grain quality traits and electrical properties was obtained for both the conductive (Z) and capacitive (Cp, Cs) parameters in the entire analyzed range of current frequencies. The GR application during cultivation hampers the possibility of using electrical parameters to assess grain quality. In turn, the quality of the grain produced WGR can be effectively assessed using the Z, Cp, and Cs parameters in the entire measuring frequency range (1 kHz-1MHz), while in the variant with GR, only impedance (Z), measured at high frequencies (100 kHz, 1MHz) can be used.
