ECOLOGICAL TEST OF PROMISING LINES OF BARLEY
Evaluation of adaptability and character stability has an important place in plant breeding. The results of ecological test of 5 productive lines created atV.V. Dokuchaev Scientific Research Institute of Agriculture of the Central Black Earth Regionare presented. Researches were conducted in 4 different on edaphoclimatic conditions localities of the Central Black Earth Zone: Kamennaya Steppe and Mitrofanovka (Voronezh region), Tambov and Kursk.In competitive variety trial in the conditions of Kamennaya Steppe these lines had higher yield capacity in comparison with the productive standards. High plasticity and ultra stability were shown by lines 4/16 and 29/16. During two years of ecological study, growing conditions were rather contrasting - the environment indicator varied from 20.73 to 17.95.In 2017, the lines 40/16 and 41/16 showed weak drought resistancein the conditions of Mitrofanovka. These lines are of the intensive type, have the high crop capacity and will be used as base lines.The high-yield line 29/16 was the best in terms of the level of stability to stress conditions and degree of ecological adaptation. The lines 29/16 and 33/16 are going to be presented for the State variety trial by the indexes of the yield capacity and adaptability.
