New version Explanatory Notes on Essentially Derived Varieties

The new Explanatory Notes provide clarification regarding the following subjects:

• Mutants are per se predominantly derived from the initial variety. This concerns both natural mutants and genetically modified mutants.
• There is no maximum number of differences in characteristics between the initial variety and those of the EDV, which have arisen as a result of plantbreeding.
• If there is a new characteristic resulting from the breeding of the (initial) variety, this can also be a "substantial/essential characteristic". This means that if a essentially derived variety differs from the initial variety in 1 or more important characteristics (e.g., a valuable resistance), this essentially derived variety does not fall outside the scope of the initial variety.
