The Forage Legume Descriptors list was developed by a subcommittee, from the Commission of the European Communities' (CEC) Programme Committee for Plant Disease Resistance Breeding and the use of Genebanks. The final list combines experience from National List Descriptors, UPOV Descriptor Lists and was produced with advice and according to the standard format of the International Board for Plant Genetic Resources (IBPGR).
The sub—committee under the chairmanship of Dr.S. Andersen carried out its deliberations, mainly by correspondence‘over the period 1979—83.
