Comprehensive evaluation of spring barley breeding lines in yield, stability and tolerance to biotic and abiotic factors under condition of the central part of the Ukrainian Forest-Steppe

Purpose. Identification of spring barley promising breeding lines with combination adaptive traits under conditions the central part Ukrainian Forest-Steppe. Methods. Field trial, laboratory-field analysis drought tolerance, statistical and graphical experimental data. Results. The variance AMMI model showed that largest contribution to general variation (85.78%) had environmental (years research). value genotype was 8.21%, by environment interaction 6.01%. first second principal components both GGE biplot explained more than 85% genotype-environment interaction. Spring ‘Deficiens 5162’, ‘Nutans 5073’ 5161’ superior yield performance relative stability through years according biplot. With GYT it has been determined 5162’ also significantly predominated over other genotypes in terms a number – 1000 kernels weight, resistance pathogens. Breeding 5161’, 4966’, 4705’, 4816’, 5184’, 5193’, which exceeded mean trial may have practical significance process for creation new initial material. Conclusions. As result complex evaluation when using AMMI, models optimal yield, stability, thousand kernel weight tolerance abiotic biotic factors identified
