Abstract
Due to climate change and water scarcity, there is a need to create droughtresistant and low-water-consumption alfalfa varieties per unit of production. It is the most in-demand crop in the feed industry of Kazakhstan. There are 7 wild alfalfa species in the flora of Kazakhstan. Among them, the more common Medicago falcata L. is a drought-resistant species with numerous ecotypes. Ecotypes of this species are involved in backcrossing crosses with cultured alfalfa M.sativa L. as a source to enhance the adaptive potential of crops in conditions of water scarcity in the region. This article is devoted to the use of the positive properties of this species in breeding in order to transfer them to the cultural species Medicago sativa L. Backcrossing is used. The original interspecific hybrids from M. falcata L. and M. sativa L. were re-crossed with M. sativa L. in the backcross system in generations BC1 – BC3 to displace undesirable signs of M. falcata L.: hardness, lying bush type, stunting. Backcross hybrids have been obtained, which are close to M. sativa L. in terms of architonics (phenotype) and regrowth. They can serve as a starting material for the creation of varieties with an increased level of drought resistance
