Ninety-nine F4 lines from the cross Lennox × Stadler of common wheat (Triticum aestivum L.) ranged widely in both kernel hardness and kernel protein content. A nonsignificant correlation of r = −0.17 showed the absence of any tendency for hardness and high protein to be associated, contrary to what might be expected from the association found in commercial cultivars.

The results of research at the department of grain breeding and seed production in 2015–2017 on the territory of the grain-ploughed crop rotation of the State Enterprise of the experimental farm «Chabany» of the NSC «Institute of Agriculture NAAN» located in the Fastiv district of Kyiv region are presented. We studied 850 lines of introgression obtained as a result of remote hybridization in previous studies. 10 lines with a grain yield from 788.2 to 949.4 g per square meter were identified, a high grain yield was found in lines 2555 and 2555/2 (949.4 and 912.1 g, respectively). The 12,2/1 line with a 1000-grain weight of 53.6 g and an index of grain weight from an ear of 2.0 g significantly exceeded the standard variety by 8.6 g and 0.56 g, respectively. In terms of quality indicators, the protein content in the grain of the selected lines was at the level of 16.8–17.9%, gluten 29.7–32.12%, Green indicator 65.7–74.7% and significantly exceeded the Standard Polesskaya 90 variety by 2.7–3.8%, 5.1–7.5% and 20.6–29.6%, respectively. Lines that are advisable to use to obtain the best combination of economically valuable traits and biological properties for a complex of traits are identified. Lines 2557, 2555, 2559, 11,2, — yield per m2, ear length, protein content in grain, gluten, Green indicator, disease resistance and winter hardiness; in addition, line 2557 — the number of spikelets in an ear; lines 2555 and 2559 — the number of spikelets, the number of grains in an ear; line 2555 — mass of grains per ear. Lines 2/1 and 12,2/1 — yield per 1 m2, number of spikelet’s, number of grains in an ear, weight of grains per ear, protein and gluten content in a grain, Zeleny indicator, disease resistance and winter hardiness; in addition, line 12,2/1 is the mass of 1000 grains and the length of the ear, lines 2533/2, 2555/2, 2558/1 and 2561/1 — the content of protein, gluten in the grain, Green indicator, disease resistance and winter hardiness; in addition, line 2555/2 for the yield from 1 m2. The use of remote crosses of Triticum aestivum L. with Aegilops species made it possible to create a wide source material that is of interest for obtaining highyielding, winter-hardy and disease-resistant winter wheat varieties with high grain quality in the foreststeppe of Ukraine and will be used in the following breeding programs.

Aim. To investigate the functionality of the transgene in the seed generation (T2) of genetically modified winter wheat plants (Triticum aestivum L.) in terms of productivity in conditions of normal and insufficient water supply. Methods. Determination of yield structure and protein content. Results. The indicators of productivity of control and T2 biotechnological plants under normal growing conditions and water deficit are analyzed. The quantitative composition of protein in the conditions before and after osmotic stress and in the period of rehydration was determined. Conclusions. It is shown that under the action of water deficit there is a decrease in productivity for all studied plants. In this case, genetically modified plants had an advantage in the main elements of the crop structure over the original form under both analyzed growing conditions. It was found that under normal conditions of hydration, the amount of protein in the studied plants did not differ significantly. An increase in its content in control plants under the action of osmotic stress was recorded, which may indicate the synthesis of stress response proteins. Decreased protein content during rehydration may indicate the passage of normal metabolic processes. Keywords: Triticum aestivum L., biotechnological plants, proline dehydrogenase gene, structural analysis of yield, osmostability.
