Study of the regeneration processes and raising the efficiency of rape (Brassica napus) organs and tissues cultivation in vitro methods, as well as the achievement of a stable yield of proper regenerants were realized in the conditions of the Republic of Belarus. The obtained data specified the possibility of generation of rape finished regenerants in vitro culture without additional passages and transfers by means of effectively selected concentrations of phytohormones and biologically active substances, which made it possible to realize principles of totipotency and polarity of crop vegetative organs. On the explant part which was submerged into culture medium there was formed a root, and on opposite one - the morphogen structures. The possibility of obtaining rape regenerants from hypocotyls segments by straight regeneration was studied. Application of the analyzed substances considerably simplified and reduced the price of process of full regenerants formation, and made it possible to receive a wide spectrum of various forms that was important for selection process due to the opportunity to select valuable (in protein content) samples for the further studies and their inclusion into production process
