The purpose of the research: Collection of wild ecotypes of forage grasses on the natural landscapes of Kazakhstan, their study in culture for the expansion of the gene pool and use in recursive selection to enhance the adaptive characteristics of the varieties being created. Research methods: collection of wild ecotypes of leguminous grasses through the organization of an expedition along established routes, carried out by harvesting seeds. The study of them was carried out according to the methods of VIR named. N.I. Vavilov. Results of the research: Expeditions were carried out on the territory of Almaty (2015-2017), Zhambyl (2015), South Kazakhstan (2015) and East Kazakhstan regions (2016-2017). Prior to harvesting, beans were the priority. Sampling was carried out by seeds. As a result of the expedition, 201 samples were collected with a brief description of the site of their growth and morphological and biological features. including for alfalfa 162 specimens, bottoms - 25, sainfoins - 7, clover - 5 and lyadventu -2. According to the results of 1-3 year study in the conditions of introductory nurseries, 15 samples of alfalfa were selected as sources for the complex - economic-valuable traits for further use in recurrent breeding.
