Methods of the breeding acceleration are aimed to obtaining the greatest number of seedlings and rapid entry into fruitage. Due to contamination by phylloxera the cultivation of own-rooted hybrid nursery grapes is difficult, a large percentage of seedlings is ruined and did not come into fruitage. This work is aimed at increasing in efficiency of the breeding process due to receiving of more hybrid seeds and conservation of genofund. This is achieved by more effective pollination of inflorescences and more hybrid seeds while reducing the volume of castration, increase in germination of seeds and vitality of seedlings, transfer of hybrid nursery in inoculated culture in the early stages of development of seedlings, with following selection and study of elite seedlings already in the nursery grafted hybrid that eliminates the premature death of the hybrid seedlings from phylloxera. To increase in the yield of hybrid seeds it is recommended the treatment of maternal inflorescences forms by physiological active substances as Krezatsin and Sweet 3-5 days before flowering. At the stage of sowing seeds � soak hybrid seeds in the solution of growth regulators for 1 hour: Krezatsin, Mival, Zircon and Emistim. At the stage of seedlings growing in the first year it is recommended three treatments of seedlings with a solution of growth regulators: Nikfan, Bigus, Larixin and Zircon. The application of growth regulators allows us to transfer the seedlings by the method of green grafting on rootstock bushes in the first or second year of life, that saves them from premature ruin from phylloxera and accelerates the timing of the fruiting stage of 2 times. As a result, the efficiency of the breeding process increases due to earlier time of seedlings selection to the elite and reducing of seedlings loss from phylloxera of 2-10 times.
