Title:
COMPARISON OF DROUGHT TOLERANCE OF CULTIVATED ALFALFA (MEDICAGO SATIVA L.) VARIETIES
Financing:
The study was conducted as part of an international project on "Animal Protein Cultivation and Fodder Production" funded by the Ministry of Culture and Tourism of the Republic of Turkey and the Coordinating Agency of the Embassy of Mongolia in Turkey (TIKA).

Annotation:
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.
Keywords:
blue flowered alfalfa Gozlu-1 variety, yellow flowered alfalfa Burgaltai variety, drought stress tolerance, morphological and physiological parameters.

Conclusion
To determine the drought tolerance of alfalfa varieties by seed germination intensity and physiological parameters, Gozlu-1 variety is 23.2-100% more resistant than Burgaltai variety.
Gozlu-1 variety germinated better than Burgaltai variety in terms of drought tolerance of alfalfa varieties.
The chlorophyll content in the leaves of alfalfa plants affected by drought showed that as the concentration increased, the amount of chlorophyll in the plant decreased and the morphological changes were stronger than in the control plants.
Gozlu-1 variety is considered to be suitable for semi-irrigated and non-irrigated conditions due to its early drought tolerance and drought tolerance of Burgaltai variety according to some morphological parameters.
