Results of the formation of a selection core of carp with increased fertility of females
Abstract
The article presents the results of a study of the working and relative working fertility of carp females during the formation of a selection gene pool and the first generation obtained from the original material. During the formation of a carp gene pool characterized by increased fertility, females with well-defined sexual characteristics of older age groups (8—10 yearlings) were selected. Selection by fertility level was carried out with an intensity of about 40.0 %. The females selected to obtain selection offspring gave up eggs completely, without blood clots. A comparative assessment of the selection groups of the original gene pool and the first generation of carp with potentially increased fertility was carried out with the average indicators of collection breeds and lines of Belarusian and foreign selection, the spawning of which was carried out simultaneously under the same conditions with the selection material. Despite the fact that the fertility of females selected during the formation of the initial selection material was higher than in the first generation, the advantage of the selection group compared to purebred collection material, the spawning of which took place simultaneously and under the same conditions, remains.
