Alfalfa is a perennial fodder plant with high nutritional value, efficient grass yield and high protein content [Erdenejav, 2015]. Drought stress is a major environmental factor that affects the germination and growth stages of plants. In this study, the drought tolerance of Turkish alfalfa variety, Gozlu-1 and Mongolian alfalfa variety, Burgaltai was compared using polyethylene glycol (PEG 20 000) and mannitol both in vitro and ex vitro. According to the results of the study, the germination rate of Gozlu-1 variety in drought was 4.4-20.2% better than that of Burgaltai variety. When comparing the alfalfa varieties according to some morphological parameters that indicates the resistance of artificial drought, Gozlu-1 variety showed 8.4% more resistance than Burgaltai variety, and Gozlu-1 variety has 17.5-28% more water absorption intensity than Burgaltai variety.
