Aim. In the second half of the 20th and the beginning of the 21st century, there were significant changes in the hemp growing that affected the improvement of morphological, biological and economic properties, by providing the opportunity, on the example of new varieties, to declare the creation of a new subset of sown hemp in which the main achievements of breeders and seedlings were accumulated. Methods. With the creation of the Institute of Bast Crops, scientific breeding has begun, based on improved and developed new breeding methods that include several significant steps as increasing of the yield of created monoecious form, as the elimination of their narcotic properties. Results. For the first time in the world, non-drug hemp that can produce high yields of straw, fiber and seeds while maintaining immunity to damage to pests and diseases were created. Conclusions. Responding to the doubts of tax of collectors and botanists about the classification of the hemp family, we share the opinion of the first scientists and our teachers that include Cannabis sativa L. and Cannabis indica L. to one species of Cannabis sativa L., combining all kinds and varieties. The elimination of a number of high-yielding varieties of non-drug monoecious hemp, which became the result of long-term breeding, testifies the creation of a new variety of Cannabis sativa L. convar non-narcotic Vyrovets, emphasizing the leadership and executive role of Professor V. Vyrovets during a long selection process.

Keywords: hemp, genus, variety, geographical types, selection, productivity, elimination of narcotic.
