Evaluation of winter hardiness and drought resistance of alfalfa varieties in the conditions of Northern Kazakhstan

Research on the study of the adaptive properties of varieties of alfalfa variable for introduction into the forage production system in the sharply continental conditions of Northern Kazakhstan is an urgent task. The aim of the research is a comparative assessment of alfalfa varieties of different ecological and geographical origin in the conditions of the region. Experimental work was carried out on the basis of stationary field experiments, laid down in the Research and Production Center for Grain Farming named after. A.I. Baraev. The scheme of the experiment, which included 32 varieties of different ecological and geographical origin, including 10 varieties of Kazakhstan selection, 18 varieties of Russian selection, 3 varieties of Canadian selection and 1 variety - Ukrainian. Varieties Raikhan, Shortandinskaya 2, Karaganda 1 Karabalykskaya rainbow, Karabalykskaya Zhemchuzhina, Lyutsiya 14, Lazurnaya of Kazakh selection, varieties Guzel, Muslima, Sarga, Bibinur, Tatar pasture, Uralochka, Nakhodka of Russian selection and varieties Ferax, Rangelander of Canadian selection had an average variability of the trait, about as evidenced by the coefficient of variation V ≤ 20%. .6% drought tolerance.
