Due to such qualities as plasticity and relative non-wholesome cultivation, carrots are cultivated in most countries of the world. Carrot roots are a valuable source of vitamins A, B, B2, B6, B12, C, RR, E, R. Agroecological conditions of the region allow to cultivate carrots in the open ground. Astrakhan region is not yet characterized by high production rates, as its cultivation can be done only under irrigation. The article considers the influence of agroecological conditions on crop yield and adaptability of garden carrots cultivars in the arid zone of the Caspian region. Experiments on studying the carrots cultivars was carried out on the fields of Precaspian Agrarian Federal Scientific Center of the RAS in 2017-2019. The purpose of the research was to study garden carrots cultivars from collection of plant genetic resources of Vavilov Institute for the selection of high-productive and more adapted samples. The object of research was 17 types of carrots from the world Vavilov collection. Based on three-year studies on yield, we can distinguish the following cultivars: Berlanda F1 (Netherlands), Nantese (Italy) and Imperator Type 9-11 (USA) with yield of 68.4 to 75.2 t/ha. The coefficient adaptability was higher than 1, in the varieties Berlanda F1 (Netherlands), Nantese (Italy), F1 Eagle (Canada), Imperator Type 9-11 (USA), Wav-88 (Germany), Surazhevskaya-1 (Russia). They have ability to adapt to difficult growing conditions and produce consistently high yields. The samples selected can be used in the future to create new cultivars and hybrids for conditions of the Caspian region.</p>table carrotscultivarhybridadaptationyieldCaspian plainAstrakhan regionстоловая морковьсортгибридадаптированные сортообразцыурожайностьПрикаспийская низменностьАстраханская область[Stolarczyk J, Janick J.
