The article presents results of comparative assessment of productivity and tribal qualities of six breeds of turkeys at the gene pool economy selection and genetic center «North Caucasus Zonal Poultry Experimental Station» and populations of blue and red turkeys. Among the studied breeds best egg production for primary and middle layers ащк 20 weeks of productive period is noted in silver North Caucasian breed: 50,33 and 64,10 eggs respectively, at intensity 45,19%. For the turkeys of the new gene pool this indicator was more in blue turkeys – 49,32 and 59,28 eggs for primary and middle layers respectively. The highest egg mass was marked in white North Caucasian turkeys – 82,7 g, with Haugh Units (HU) highest value and form index – Uzbek pale yellow breed – 83,6; 69,3% respectively. Thus, we can conclude that selection with domestic breeds of turkeys in centre of collective usage Bioresource breeds collection Selection and Genetic Center «North Caucasus Zonal Poultry Experimental Station» is conducted up to the mark; breeds are preserved and rationally used depending on the tasks. Silver turkeys of the North Caucasian breed and blue turkeys of the new gene pool possessed the best productive qualities.

The objects of research are representatives of the genus Malus growing in the Kuban zone of the North Caucasus region. The purpose of the research is the breeding improvement of the of apple southern assortment on the basis of the development of the scientific direction “Introduction, variety study and breeding of pome crops in the North Caucasus and the creation of promising domestic varieties with improved adaptability and quality. The history of the creation and development of this scientific direction of the scientific school “Southern Horticulture” in the North Caucasus, the founder of which was Lev M. Sergeev (1886-1980. Under his leadership, the first breeding programs for seed crops (apple, pear, quince) for the North Caucasus region were developed, the priority of which was to improve the characteristics of productivity and quality characteristics of fruits; with his active participation, a network of gossortuchastok was organized in the North Caucasus and by the end of 1947 a zoned assortment of the main fruit crops of the south of Russia was formed. At present, the development of the above-mentioned scientific direction has been continued in the works of L. M. Sergeev, original studies of which are based on the use of a complex of classical and improved methods for creating and evaluating breeding material, modern achievements in molecular genetics, biochemistry, cytology, and are aimed at creating domestic varieties with improved productivity and quality of fruits, with high resistance to abiostressors and the main fungal pathogens of the North Caucasus. In recent years, the gene pool of the apple tree has been significantly updated, numbering 436 specimens of various ecological and geographical origin and ploidy, most of which are from Russia (49 %), Western European countries (18 %), and the USA (17 %). Over the years of research, scientists from North Caucasian Federal Scientific Center of Horticulture, Viticulture, Wine-making have created and submitted for State variety testing 81 new apple varieties, including 25 varieties created in collaboration with scientists from All- Russian Research Institute for Fruit Crops Breeding, I. V. Michurin Federal Research Center and others. 36 apple varieties obtained on the basis of the use of spontaneous and induced mutagenesis, an improved method of polyploidy, directed, repeated and geographically distant hybridization were included in the State Register of Breeding Achievements approved for use in the North Caucasus region.

Выявлен вклад тюркского по происхождению компонента в генофонд различных этносов Дагестана и Северного Кавказа, который присутствует не только у тюркоязычных популяций, но и у соседних с ними. В горных популяциях Дагестана, в отличие от равнинных, тюркский компонент практически полностью отсутствует. The contribution of Turkic genetic component to the gene pool of various ethnic groups of Dagestan and the North Caucasus, which is present not only in Turkic-speaking populations, but also in neighboring ones, is revealed. In the mountain populations of Dagestan, unlike the plains, the Turkic component is almost completely absent.
