Hemp is one of the oldest crops in the world and can be used in very different ways. Hemp cultivation was forbidden in Germany since 1982. Since 1996 hemp with less than 0.3 per cent THC content can be grown. To evaluate the available genetic hemp resources 14 monoecious and 26 dioecious hemp varieties and strains were grown in the field in 1996 and analysed for morphological traits. A large variability was found for plant height at different dates, blooming time, stem diameter, fresh and dry… Expand

Apical bud removal increased seed yield in hemp (Cannabis sativa L.)
TLDR
It is maintained that hemp producers can achieve a larger seed yield not only by selecting an appropriate cultivar and row distance but also by removing apical buds. Expand
The relationship of stem and seed yields to flowering phenology and sex expression in monoecious hemp (Cannabis sativa L.)
TLDR
According to the results, harvesting the seeds in addition to the stems in monoecious hemp requires early sowing and the selection of feminized early or mid-early cultivars, earliness depending on the climatic conditions in the cultivation area, therefore, it might be agriculturally valuable to take sex expression into account during the Selection of cultivars that are adapted to a dual purpose. Expand
In vitro germplasm conservation of high Δ9-tetrahydrocannabinol yielding elite clones of Cannabis sativa L. under slow growth conditions
TLDR
This study is of high significance since the encapsulation technology would allow the prolonged storage (thus reducing the cost of labor) of high-yielding C. sativa germplasm selected for the isolation of THC, a high-value bulk active pharmaceutic. Expand

Research in plant genetic resources 1978–2003: General index of the second 25 volumes 'Kulturpflanze'/'GRACE'
TLDR
A general index of the second 25 volumes of 'Kulturpflanze' 1978–1990/'GRACE' (Genetic Resources and Crop Evolution) 1992–2003 is provided and can be considered as a unique source for research in plant genetic resources. Expand

Characterisation of Cannabis accessions with regard to cannabinoid content in relation to other plant characters
TLDR
Variation within populations for cannabinoid content, and consistency of chemical characters at the population level were investigated and various combinations of cannabinoid content and other economic plant characters were observed, thus a breeding programme will not be hampered by strict linkage.
