FIELD: agriculture.
SUBSTANCE: at reception of seeds F0 and reproduction of hybrids F1 in a 3 pairs of leaves it is spent a decapitation of all plants. Then, in a budding initial stage all genets with completely androecial flowers in panicles are removed with a root and they are leaved for unitary crossbreeding on hybridization plots of genets with completely gynaecial, subandroecial, monoecial and subgynaecial flowers, and on seet-breeding plots - only genets with subandroecial, monoecial and subgynaecial flowers.
EFFECT: seed yield increases and process of seed-growing reproduction and industrial use of hybrids of hemp is sped up.
