Papp V. Experimental Study of the Creation of a New Intra-Breed Type of Carpathian Bees

The dissertation presents the results of a completed scientific study on the creation of a new intra-breed type of Carpathian bees, the name «Synevyr» which is given according to the region of origin of the original genetic material. In bee families of type «Synevyr» the incidence of typical gray color of working bees has increased by 43.0 % (p<0.001), gray with silver-gray tint (type B2) has decreased by 3.1 % (p<0.01), and gray with single cases of rust-brown stripes on the first visible tergite – by 31.1 % (p<0.001), atypical gray color with single cases of rust-brown stripes on the first visible tergite (type B4) was not recorded already in F3 generation of direct descendants. The number of uterus with black belly color has increased by 38.8 % (p<0.001) and with cherry blossom color has decreased by 1.0 % (p<0.05). The number of uterus with atypical color decreased, namely, dark brown color with 1-2 barely noticeable inter-tergitic strips of light brown color – by 20.1 % (p<0.001) and tiger color with well-marked intertergitic strips of yellowbrown color – 17.7 % (p<0.001). The creation of a new intra-breed type of Carpathian bee «Synevyr» was the result of the long section study. A breeding apiary with a breeding kernel was created, in which work with the intra-breed type of bees «Synevyr» was provided for the annual selection of the breeding group by the average selection coefficient in the maternal line of 26.3 %, in the parent – 22.7 %, with an average coefficient of 48.6 1.51 %. For structuring of genealogical groups 795 branches were created – 771 branches with uterus of natural mating and 24 branches with uterus of artificial insemination. The newly created type is characterized by increased uterine egg production (1814±22.9 eggs per day), high honey productivity in the harsh natural and climatic conditions of the Carpathian mountain forest zone, including gross (9.2±0.32 kg) and marketable (7.3±0.25 kg). At the same time, for the creation of a new type of Carpathian bees, additional prerequisites for reliability have been laid down to solve the problem of preserving its gene pool, replenishing the variable base for carrying out industrial crossings, laying new lines and types. The proximity of the bees of the Ukrainian Carpathians to the bees of the national breed group (blood ratio 83.5–92.0 %) is established, so they can be called Apis mellifera carnica var ukrainiсa carpatica and according to the conducted research and therefore, they can be a branch of the Ukrainian honey bee breed group.
