Variability of the sign of oil content in hemp seeds depending on breeding methods

Abstract

Traditionally, hemp is considered a fibrous crop, but the scope of their economic use is constantly expanding, recently increasing demand for seeds as a food product and hemp oil, and in the breeding of intensified direction to increase the oil content in seeds and improve its fatty acid composition. productivity. The article shows that the creation of the source breeding material of industrial hemp with high oil content in seeds can be carried out using different breeding methods – improving selection, self-pollination, synthetic breedingn, different types of hybridization – intervarietal, sortoliniary, linear and interlinear. The oil content of the created breeding material was increased from 19,38–37,50 to 33,14–53,00 %. Success in breeding and obtaining valuable material depends on the successful combination of the source material and the method of breeding.
