Comprehensive evaluation of spring barley yield and tolerance to abiotic and biotic stresses
The results of comprehensive evaluation in 2018-2020 of 96 spring barley accessions of different ecological origin under conditions of the central part of the Ukrainian Forest-Steppe are presented. As a result of field trials and laboratory investigation, the new genetic sources in terms of high and stable grain yield, relative tolerance to drought, lodging resistance, and resistance to diseases have been identified. Accordingly to the GYT (genotype by yield*trait) biplot, the accessions Skald (POL), Despina (DEU), Kormoran (POL), Almonte (CAN), Suveren (POL), Dar Nosivshchyny (UKR), Scarb (POL), Vienna (AUT), AC Alma (CAN), Smarahd (UKR) are characterized with increased yield and combination of a set of adaptive traits. The new genetic sources identified are valuable in spring barley breeding to develop an initial material with combination of yield, its stability, and tolerance to the most widespread abiotic and biotic stresses under conditions of the central part of Ukrainian Forest-Steppe.
