Hemp grown for fibre has a long tradition in Germany and Europe. But, hemp cultivation was banned in Germany from 1982 to 1996. As a result, processing was not developed and hemp breeding was not established. However, hemp cultivation can contribute to the objectives of the Green Deal and is to be promoted by decision of the European Commission. The common goal of the independent projects in Uruguay and Germany is to identify genotypes suitable for cultivation in the respective climatic regions and to create the conditions for future breeding programmes. In addition, the cultivation process will be optimised in order to ensure stable yields and quality. In this project, different fibre hemp accessions will be characterised to obtain a general overview of the available genetic material and to select suitable accessions for cultivation in Germany. The assortment to be tested will be composed of European, Uruguayan and US genotypes. In addition to traditional phenotyping, UAV-based sensors such as RGB, multispectral and thermal cameras will also be used. The data obtained from phenotyping can be used to identify potential genetic resources for future breeding work. In field trials with different sowing dates at two locations plant growth and development as well as yield formation and fibre quality will be investigated. Key parameters are the leaf area index, the crop height and the developmental stage of the plants. By differentiating the sowing dates, early sowing and late sowing tolerance can also be analysed. Genotypic effects and genotype-environment-interactions will be analysed during vegetation period using soil and UAV-based sensors and assessments. In addition, the individual fibre fractions as well as the THC content will be analysed. Similar trials will also be carried out in Uruguay in close collaboration. This will provide insight into the plasticity of hemp phenotypes in different geographical regions and climates. Hemp grown for fibre has a long tradition in Germany and Europe.
