In the present study, in a panel of promising winter and facultative barley (Hordeum vulgare L.) breeding lines, the peculiarities of yield performance and its combination with resistance (tolerance) to the most common under conditions of the Ukrainian Forest-Steppe abiotic and biotic stresses have been determined. In 2016-17-2018-19 the breeding lines were differentiated based on grain yield, thousand kernel weight, frost resistance, leakage of electrolytes, relative drought tolerance, lodging resistance, and resistance to powdery mildew (caused by Blumeria graminis (DC.) E. O. Speer, f. sp. hordei emend. É. J. Marchal (anamorph Oidium monilioides Link)), spot blotch (caused by Cochliobolus sativus (anamorph Bipolaris sorokiniana [Sacc.] Shoem.)), and leaf rust (caused by Puccinia hordei Otth.). GYT (genotype by yield x trait) biplot model was used for comprehensive evaluation of the breeding lines by a combination of yield with a complex of traits. As a result, the winter breeding line 'Pallidum 5096' and facultative breeding line 'Pallidum 5110' superior to others in terms of yield x traits combinations have been identified. These breeding lines as new varieties 'MIP Atlas' and 'MIP Yanus' accordingly have been submitted to the Ukrainian Institute for Plant Variety Examination for further State Qualification Examination. The winter ('Pallidum 5134', 'Pallidum 5097', 'Pallidum 5024', 'Pallidum 5090', and 'Pallidum 5130') and facultative ('Pallidum 5153', 'Pallidum 5102', 'Pallidum 5126', and 'Pallidum 5131') breeding lines can be used as valuable genetic sources in breeding programs in Ukraine and some other Central a nd Eastern European countries.
