Akhal-Teke is the ancient cultural horse breed of oriental origin. The study of genetic features different subpopulations of Akhal-Teke breed was carried out on 17 loci of DNA microsatellites (VHL20, HTG4, AHT4, HMS7, HTG6, AHT5, HMS6, ASB23, ASB2, HTG10, HTG7, HMS3, HMS2, ASB17, LEX3, HMS1 and CA425) to assess their genetic differentiation. The results of DNA typing of 5457 Akhal-Teke horses on 17 microsatellite loci show that gene pool of world population is represented by 121 alleles, among which 98 are found in all countries. Comparative analysis of genotypes of horses representing different subpopulations indicates that they differ in the number of alleles (100-117), allele frequencies, the level of polymorphism Ae (3.40-3.91) and the degree of observed heterozygosity Ho (0.661-0.724). The genetic distances between the subpopulations varied in range from 0.007 (Russia – CIS) to 0.051 (Czechia – Turkmenistan). Correspondence to HWE was maintained in all countries, which confirms the negative value Fis. Genetic options of the Akhal-Teke by index Fst varied in a range 0.001 -0.078 at the mean value Fst=0.022. Cluster analysis demonstrated more close relationship between Russian, CIS and European subpopulations.

Research and production introduction of the multipurpose use of narrow-leaved lupin varieties in fodder production in the region will increase the agricultural efficiency with developed dairy cattle breeding. The aim of the research was to study the adaptive properties of narrow-leaved lupin varieties in the Udmurt Republic, to analyze the efficiency of its cultivation. The studies were carried out in the southern agroclimatic region of the Udmurt Republic on gray forest soil. The arable soil layer was characterized by a humus content of 2.1-2.6%, mobile phosphorus - 100-101 mg/kg of soil, mobile potassium - 101-170 mg/kg of soil, and pH KCl from moderately acidic to almost neutral (5.0 -5.6). By the content of crude protein (32%) in grain, narrow-leaved lupin is the leader in the region among leguminous crops. During the research period, a relatively high yield of 1.36-4.95 t/ha was formed by Snezhet’ variety. Varieties Snezhet’ and Vector (S2d = 0.05…0.14) were distinguished by their high resistance to changes in agro-ecological conditions. The combination of ecological plasticity indicators (bi = 0.60) and phenotypic stability (S2d = 0.60) of Crystal variety indicates its high adaptive properties.
