Abstract. The article presents the results of the evaluation of parental forms of different origins. In order to obtain valuable parent material of monoecious hemp, varieties of the Central Russian ecotype (Surskaya, Vera, Nadezhda, Yuliana) and the southern ecotype (Zenitsa, Omegadar 1, Kubanka, Yuzhanka) were included in the crossing. The purpose of the study is to determine the presence of genetic divergence between the varieties of the Central Russian and southern ecotypes and to justify the selection of parental forms for hybridization in the breeding of nondrug monoecious hemp. Statistical characteristics of the main indicators of quantitative traits of the southern and Central Russian ecotypes are given. As a result of the studies carried out, data were obtained that allow a general conclusion that the parental varieties of different ecotypes included in the hybridization with the purpose of obtaining new parent material for hemp breeding have a 95 % probability of genetic distance in the following traits: length of vegetation period, plant height, weight of 1000 seeds, weight of seeds per plant and yield characteristics expressed by the amount of fiber obtained from a unit area. The use of parental forms characterized by hereditarily different traits and characteristics in the hybridization increases the likelihood that new valuable recombinant forms will be selected for hemp breeding.
Keywords: breeding, hemp, ecotype, nondrug variety, hybridization, parental forms.
