Abstract
Ideal schemes do not exist and will very likely never exist.
On the other hand: many schemes are in operation and not two of them are the same.
On paper, they look all very well.
In practice, however, they differ considerably – as I have discovered in the course of years – with respect to the measure of security they offer to the ‘consumer’ of the trees, i.e. the fruitgrower.
This security must not only have reference to the virus-status of the material, but first and for all on the trueness-to-name, the purity of the variety and the external quality.
Only secondary is the health status, in which the virus-diseases play an important but not the only role.

This security must not only have reference to the virus-status of the material, but first and for all on the trueness-to-name, the purity of the variety and the external quality.
Only secondary is the health status, in which the virus-diseases play an important but not the only role.
All schemes, however, should have the same goal: to ensure that the material reaches its final destination in good condition and under the correct designation with respect to the trueness-to-name, the purity, the external and the internal quality and with respect to this last point: the correct designation of the virus-status.
How this goal can be reached is a matter of organisation in which the following points should be considered:
- How sufficient pomological security throughout the whole procedure can be reached with respect to the trueness-to-name and the purity of the variety or rootstock.
- How the indexing program for virus-diseases for the basic material should be and how security can be reached with respect to the freedom from other pests and diseases.
- Under which conditions the basic material has to be maintained to ensure freedom from re-infestation.
- The number of steps needed to multiply the basic material to such an extent, that general distribution can take place to all nurserymen involved and whether the nurserymen can be allowed to use also material, derived from earlier received material from the multiplication plots or not.
- An adequate control system between the basic material and the ‘consumer’ of the trees, i.e. the fruitgrower.
- The way of certification.
