Short description of the organization (max 12 lines): -
Expertise offered Inbreeding, or closely related crossing, is always connected with the decrease of phenotypical values of quantitative features in certain groups of plants. Inbreeding in self-pollinating plants (wheat, barley, peas, beans, peppers, citrus plants, cotton, etc.) is a normal phenomenon. In cross- pollinating plants and animals inbreeding can result in the action of harmful recessive genes, which in a homozygous state cause partial (sublethal and subvital genes) or full (lethal genes) destruction of organisms. Harmful influence of inbreeding is often revealed, for example, in self-pollination of corn, potatoes or cabbage (the decrease in intensity of growth, fertility; the appearance of anomaly and deformities). In hens annual coupling «brother x sister » leads to the hereditary decrease in egg-laying qualities and vitality. In human beings marriages between cousins result in the growth of frequency of hereditary diseases (especially rare ones) in children; inborn deformities, stillbirths and deaths in early age are more frequent than in unrelated marriages, by 24—48 %.
Problems to be solved and results: Stage-by-stage production of a necessary plant material will make it possible to check the necessary theoretical preconditions obtained as a result of tests on annual plants. An ultimate aim of the work is to obtain selfed lines in birch.
