Abstract Dual-purpose wheat (Triticum aestivum L.) systems increase farm sustainability by diversifying on-farm income. While these systems are common in the Southern Great Plains of the United States, they are not often utilized in the Southeast. This study aimed to evaluate pre- and post-grazing herbage mass (HM) of four winter wheat varieties managed under a dual-purpose grazing and grain production system. The winter wheat varieties evaluated were generic feed-type wheat (mixed variety, Feed), seed-type wheat (‘GA Gore’) and two forage-type varieties, ‘AGS 2024’ (AGS) and ‘Pioneer 26R41’ (Pioneer). The experiment was a completely randomized block design with n = 4. Each plot was randomly assigned either as no-grazing (CON) or grazing (GF2). Plots were grazed with cow-calf pairs that were fasted 24 h before each grazing event. Grazing was considered complete when the average stubble height was 10 cm. Herbage mass was determined using three 0.1m2-quadrats per plot and clipping to a 10 cm stubble height before (PreG) and after (PostG) each grazing event. Forage samples were then dried at 45°C for 72 h. Data were analyzed using PROC GLIMMIX of SAS (SAS Inst., Cary, NC). Differences were declared at P < 0.05. Initial HM was greater for PreG than PostG (883 and 615 kg/ha, respectively; P < 0.01). Prior to grazing, AGS (1204 kg/ha) was greater (P < 0.02) than all other varieties. Pre-grazing, there were no differences among the other varieties (776 kg/ha; P > 0.14). Post-grazing, AGS had a greater HM than Seed (788 and 391 ka/ha, respectively; P = 0.04), while all other varieties were intermediate (642 kg/ha). Herbage mass was affected by grazing frequency with CON being greater (P < 0.01) than GF2 (993 and 691 kg/ha, respectively). These results indicate that both wheat variety and grazing treatment had an effect on dual-purpose wheat herbage mass.

Dual-purpose winter wheat production is an important economic enterprise in the southern Great Plains of the United States. Because of the complex interactions involved in producing wheat grain and beef gain from a single crop, stocking density is an important decision. The objective of the research is to determine the stocking density that maximizes expected net returns from dual-purpose winter wheat production. Statistical tests rejected a conventional linear-response plateau function in favor of a linear-response stochastic plateau function. The optimal stocking density of 1.48 steers/ha (0.60 steers/acre) is 19% greater with a stochastic than with a nonstochastic plateau.

Aim. Further improvement and application of modern methods of wheat breeding of different types of development for adaptiveness caused by change in the character of manifestation of limiting environmental factors under conditions of the Southern Ukrainian Steppe. Methods. Field experiment, selection and genetic, calculation and comparison research methods were used. Wheat varieties of different genetic and ecological origin under different growing conditions were examined. Results. Analysis of the parameters of plasticity and stability of the elements of the yield structure in winter wheat varieties under different growing conditions revealed that their variability depends on both genotype and ecological gradients. For instance, by the weight of grain from ears only the varieties Kirena and Yaroslavna were distinguished by a high reaction to changes in growing conditions (bi= 1,215 – 1,635) among the analyzed genotypes, the other varieties Askaniiska, Askaniiska Berehynia, Znakhidka odeska and Klarisa manifested quite high plasticity (bi= 0,454 – 0,816). There was an analogous situation in the formation of the number of grains per ear. It is necessary to highlight an important biological feature of these varieties which formed the highest actual productivity under late sowing conditions and different sowing rates when compared to other varieties and realized its potentialities better. Conclusions.The research determined that every wheat variety of different development types should be considered in the aspect of its reaction to different growing conditions and to the capability of realizing genetic potential in a particular ecological region. The results of estimation of adaptiveness potential determined a high degree of homeostaticity in the winter wheat varieties Askaniiska, Askaniiska Berehynia, Perlyna and the variety of an alternative type Klarisa. Keywords: winter wheat, varieties of alternative types, adaptiveness, plasticity, stability.

In this article, the reaction of winter wheat varieties to fertilizers in irrigated soils in the varietal-soil-fertilizer system was studied and a feeding system was developed and recommended for each soil-climatic conditions and varieties. Appropriate fertilizer standards have been developed for each wheat variety, which have increased the germination, weeding, accumulation, tuberization, spike formation, dry mass accumulation, grain quality, and yield structure and yield of winter wheat. N250P200K200 kg/ha was obtained from Polovchanka variety of winter wheat at the rate of N250P200K200 kg/ha used in irrigated brown meadow soils, while in typical irrigated gray soils the yield of winter wheat was higher than N250P200K200 kg/ha of pure wheat with N250P200K200 kg/ha. Grain yield was 80.18 tons/ha from Tanya variety, 76.38 tons/ha from Krasnodar-99 variety and 82.32 tons/ha from Polovchanka variety under N200P150K150 kg/ha. Under the influence of the same optimal fertilizer standards, the growth and development of winter wheat, nutrient accumulation, and grain yield and grain quality are improved, and the efficiency of fertilizers is increased.

Dynamics of photosynthesis pigments in the leaves of different varieties of winter wheat during the vegetation period is analyzed in the paper. The accumulation of pigments in the plant depends on the physiological activity, growth and development of the plant, therefore the composition and content of photosynthesis pigments chlorophyll a, b and carotenoids reflect the general condition of the plant. The ratio of chlorophyll a / b for normal photosynthesis activity in the leaves of the plant should be at least 1:3. The object of the research is different varieties of winter wheat (Triticum aestivum L.) - 'Artist', 'Edvin', 'Skagen', 'Bertold' and 'Viola'. Field experiment was carried out at the Experimental Station of Aleksandras Stulginskis University in 2015-2016. Soil type was identified as IDg8 - k (LVg - p - w - cc) - shallow calcareous luvisol (Calc (ar) i - Epihypogleyic Luvisols). Agrochemical parameters of the soil were determined using accepted analytical methods. The content of photosynthesis pigments (chlorophyll a, b and carotenoids) in green leaf mass was determined in 96% ethyl alcohol extract applying spectrophotometric Wettstein method, “Genesys” 6 spectrophotometer. The photosynthesis productivity (Fpr) was calculated according to the formula: Fpr = 2 (M2-M1) / (L1 + L2) T. The accuracy of the data analysis was estimated according to the standard measurement deviation from the mean. The highest content of photosynthesis pigments has been accumulated by winter wheat variety 'Skagen'. The best result has been observed at the end of nodding stage. A lower content of photosynthesis pigments has been found in the leaves of 'Edvin', 'Viola' and 'Artist' varieties. The highest photosynthesis productivity of all winter wheat varieties has been recorded at the end of nodding stage, and decrease of photosynthesis productivity has been observed since milk maturity stage.

Winter Wheat Varieties

Breeding wheat with blue grain was conducted at the Crop Research Institute in Prague. Initial donor material came from the legacy of Erich von Tschermak-Seysenegg. Long-term crosses with a series of winter wheat varieties were made with the aim of transferring blue grain colour into cultivated varieties. The prospective material was later handed over to Agrotest Fyto, Ltd., Kroměříž, where line no. 6 was selected from the population RU 440. At the end of 2011, the new winter wheat variety Skorpion with blue grain was registered in Austria. It is intended for special use in the food industry. The anthocyanins which it contains are considered to offer health benefits due to their antioxidant effects.
