Abstract
Due to climate change and water shortages, there is a need to create alfalfa varieties that are drought-resistant and have low water consumption per unit of production. It is the most popular crop in the feed production of Kazakhstan. In the flora of Kazakhstan there are 7 wild species of alfalfa. Ecotypes of this species are involved in backcrossings with cultivated alfalfa M. sativa L. as a source for enhancing the adaptive potential of crops under conditions of water scarcity in the region.
Among them, the more common is Medicago falcata L., a drought-resistant species with numerous ecotypes. This article is devoted to the use of the positive properties of this species in breeding with the aim of transferring them to the cultivated 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 a backcross system in generations BC1 – BC3 to displace undesirable traits of M. falcata L.: hardness, lying type of bush, slow growth. Backcross hybrids have been obtained that are similar in architonics (phenotype) and regrowth capacity to M. sativa L. They can serve as the starting material for creating varieties with an increased level of drought resistance.
