Variability and interrelation of yield components in fiber hemp were analysed in field experiments. This research included 20 commercial varieties currently being cultivated in Europe. Significant variability was determined for plant height, stem yield, fiber content and fiber yield, so these materials can be useful as a good base for future fiber hemp breeding and production improvement. Stem diameter was predominantly determined by ecological factors, and genetic background of examined varieties had small influence on expression of this trait. Regarding expression of other yield components, influence of genetic factors was more important than environmental conditions. Correlation between analyzed traits shows that high stem and fiber yield are achieved in higher populations of fiber hemp with thicker stem. Fiber content increased with stem thickness increase.
