Water supply of crop plants is the most essential physiological condition influencing quality and quantity performance of grain yield. In a 12-year experimental series of winter wheat agronomic trials run at the Nagygombos experimental site (Hungary) the effect of water availability has been studied. The location represents the typical average lowland conditions of the country, the annual precipitation of the experimental site belonging to the 550–600 mm belt of the Northern edges of the Great Hungarian Plain, while the average depth of groundwater varies between 2 to 3 metres. Crop years with various precipitation patterns have had different impacts on crop yield quality and quantity. Yield figures were in positive correlation with annual precipitation in general. Water availability had diverse influence on quality manifestation. Good water supply has often resulted in poorer grain quality, especially wet gluten and Hagberg values have been affected by that. Drought reduced the amount of yield in general, but contributed to a better quality manifestation in some of the crop years.

Fowler, D. B. 2012. Moats hard red winter wheat. Can. J. Plant Sci. 92: 191–193. Moats is a hard red winter wheat (Triticum aestivum L.) that is eligible for grades of the Canada Western Red Winter (CWRW) wheat class. It has excellent stem and leaf rust resistance and higher grain yield and protein concentration than the Central Winter Wheat Cooperative Registration Trial CWRW grain quality check cultivar, CDC Buteo. Its grain yield is similar to the high-yielding Registration Trial check cultivar, CDC Falcon, and lower than Accipiter, which is a more recent high-yielding winter wheat cultivar released in the Canada Western General Purpose wheat class. A suitable combination of grain quality, rust resistance and yield make Moats widely adapted in the winter wheat production area of western Canada.

Wheat (Triticum aestivum L.) is one of the main foods globally. Nutrition problems associated with Zinc and Iron deficiency affect more than two billion individuals. Biofortification is a strategy believed to be sustainable, economical and easily implemented. This study evaluated the effect of combined Zn and Fe applied as foliar fertilizer to winter wheat on grain yield, quality, Zn and Fe concentration in the grains. Results showed that treatments containing high Fe increased the yield. Grain crude fat content remained unaffected. Crude fiber was enhanced up to three-fold by 60% Zn + 40% Fe5.5 (5.5 kg ha−1 of 60% Zn + 40% Fe). Moreover, 80% Zn + 20% Fe5.5 (5.5 kg ha−1 of 80% Zn + 20% Fe) was the best combination for increasing crude protein. Zinc applied alone enhanced Zn concentration in grain. In addition, Fe was slightly improved by an application of Zn and Fe in the first year, but a greater increase was observed in the second year, where 100% Fe13 (13 kg ha−1 of 100% Fe) was the best in improving Fe in grain. Foliar application of Zn and Fe is a practical approach to increase Zn and Fe concentration, and to improve the quality of wheat grains.

Aim. The goal of research was to study the effects of soil drought on the productivity of winter wheat plants (Triticum aestivum L.). Methods. Wheat plants of the cultivars of Zolotocolosa and Astarta were grown under optimal nutrition and moisture to the earing-flowering phase. After the beginning of it the experimental plants were transferred to drought conditions for 8 days, after that the optimal water supply was restored to the end of the vegetation. The yield structure was analyzed in mature plants. Results. It is established that the effect of drought in the critical phase of ontogenesis led to a decrease in plant height, ear size, mass and number of grains in it. At the same time, the number of grains in ears of plants decreased more significantly in the cultivar Zolotocolosa compared to the Astarta, especially in the tillers. The loss of grains mass from the ear was lower in cultivar Zolotocolosa than to the Astarta. Conclusions. Water deficit in the soil in the critical phase of ear-flowering led to a decrease in the productivity of wheat plants due to the inhibition of growth, the laying and the formation elements of the ear and grains, that depended on the specificity of the cultivar. Keywords: Triticum aestivum L., stem, ear, productivity, drought.

Winter Wheat Varieties

The current study is aimed at evaluating the reaction of winter wheat varieties according to cultivation technologies at a different level of intensity i.e. basic, intensive and high intensive. The cultivation technologies included fertilizers, pesticides and growth regulators at different combinations and concentrations. The experiment was established in order to determine the optimum conditions of winter wheat cultivation. Three winter wheat varieties were studied: Moskovskaya 40 (V1), Nemchinovskaya 17 (V2) and Nemchinovskaya 85 (V3). Yield performances and grain quality (measured through protein and gluten content) were determined according to the tested cultivation technologies. The results showed that the cultivation technology affected grain wheat productivity and quality on all varieties studied, since the highest yields were obtained using high intensive cultivation technology for all varieties studied, Moskovskaya 40 - 9.65 t/h, Nemchinovskaya 17 - 8.58 t/h and Nemchinovskaya 85 - 9.87 t/h. However, according to the basic technology, the yield was lower by 2064 %. The tested cultivation technologies demonstrated that high intensive cultivation technology increased wheat quality. The highest protein content (18 %) was recorded in Nemchinovskaya 85 variety. The present results give real opportunities for a largescale application of the tested cultivation technologies in different agricultural lands of Russia.

Fowler, D. B. 2014. CDC Chase hard red winter wheat. Can. J. Plant Sci. 94: 183–186. CDC Chase is a hard red winter wheat (Triticum aestivum L.) that is eligible for grades of the Canada Western Red Winter (CWRW) wheat class. High grain yield potential relative to the grain quality checks, CDC Buteo and Moats, is its primary strength. It has excellent stem, leaf, and stripe rust resistance, and low physiological leaf spot and very susceptible bunt ratings. Except for minor differences, its performance has been similar to that of CDC Buteo and Moats for the remainder of the agronomic characters measured. A suitable combination of grain quality, rust resistance, and grain yield make CDC Chase a good fit for the low to intermediate precipitation regions of western Canada.

CDC Osprey is a high-yielding, lodging-resistant, semidwarf winter wheat (Triticum aestivum L.) with good winterhardiness. CDC Osprey has excellent grain quality. It has a grain protein concentration that is similar to Norstar combined with the superior agronomic performance of CDC Kestrel in Alberta and Saskatchewan. However, more susceptible rust reactions and lower grain yields than CDC Kestrel may limit the production of CDC Osprey in southeastern Manitoba. CDC Osprey is eligible for grades of the Canada Western Red Winter Wheat class. Key words: Triticum aestivum L., cultivar description, wheat (winter)
