Aims. Authors appealed to the very eccentric theme of researches, touching position of hemp in biotaxonomy, taking into
account its signs as plasticity, economic setting and variation of pharmacy-chemical indexes depending on ecologicallygeographical terms. Methods. Modern confession of hemp in the period of hard agrarian competition, due to ability to give
a large income, is investigation of successes of breeding. On the basis of the worked out methodologies the productivity was
considerably enhanceable and new drug free varieties are created. Results. In spite of antiquity of the crop, until now doubts
are not blown about in relation to belonging of hemp to family of Cannabaceae, as other consider that hemp together with
genera of Morus and Humulus nearer to nettle (Urticaceae) or mulberry (Moraceae). Like it there are no single opinion and
relatively specifi c division: to attribute a hemp to two kinds — Cannabis sativa L. and Cannabis indica L. or only to the
fi rst. On the basis of undertaken studies and created varieties we consider that in the origin of hemp an active role belonged
to economic activity of man in certain ecologically-geographical terms that are predominating. Conclusions. The shown out
new highly productive drug free varieties testify that a new crop, that on the identity of polymorphological signs presents the
new variant of industrial hemp that can be named as Cannabis sativa L. var. non-narcotic Virovets.
Keywords: industrial hemp, families and species, breeding, drug free varieties.
