CDC Clair is a high-yielding, strong-strawed, semidwarf winter wheat (Triticum aestivum L.) with good winterhardiness. When grown in western Canada, it has the high grain yield and agronomic performance of CDC Kestrel, but improved grain quality. The grain protein concentration of CDC Clair has been higher than that of CDC Kestrel and similar to Norstar. CDC Clair is eligible for grades of the Canada Western Red Winter Wheat class. Key words: Triticum aestivum L., cultivar description, wheat (winter)

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.

Aim. Taking into account the fact that the zones of local massive chemical soil contamination could have unique conditions of the effect of gene-toxic factors on living organisms, the purpose of the research was to study yield capacity and some parameters of grain quality of productive T. aestivum L. mutants, induced by chemical techno-genic mutagenic factors of the environment. Methods. The yield from each plot was determined based on three-year data. The determination of the total protein and gluten content and the studying of the indicators of grain firmness were carried out in M6 by the method of infra-red spectroscopy (NIR). Gluten quality was determined by sedimentation indicator SDS-30. Results. Samples were selected whose yield exceeded the initial form by 1.2–9.0%. In most of them by the content of protein and gluten in grain, the indicator of sedimentation and grain firmness corresponds to the level of an initial form or does not equal it considerably. Mutant sample No. 5561 of cultivar Albatros odeskyi, induced by the contamination with the discharges of Burshtyn ThPS, was found; its yield capacity was supplemented by a serious increase of grain quality indicators. Conclusions. Using the effect of chemical techno-genic mutagenic factors of the environment, it is possible to improve the indicators of wheat yield capacity and grain quality. The expansion of the genetic diversification of the initial breeding material due to a gene-toxic effect of xenobiotics creates perspectives for its use to implement breeding-genetic programs of the improvement of wheat cultivars. Keywords: Triticum aestivum L., mutagenic factors, productive mutants, yield capacity, grain quality.
