The first methods for creation of the initial hemp material aimed at f
ixing the monoecious character in generations are inbreeding of indivi
dual monoecious plants, interbreeding of standards of monoecious hemp
and obtaining the hybrids of recurrent crossing (dioecious hemp x mono
ecious) x monoecious hemp, in combination with selection for true fema
le monoecious plants, monoecious female pestillate hemp and pestillate
hemp of monoecious plants.
