NAMING OF CLONES AND SEED SOURCES IN HORTICULTURAL PLANTS

An analysis is given of the practical use of names of horticultural plants, especially vegetative propagated plants (clones). The generative propagated plants for landscaping have special problems in naming.

An evaluation is given of the possibility of solving the practical problem of naming the cultivated plants on the basis of the Cultivated Code.

The conclusion is that the present Code solves most problems in naming horticultural plants.

The main difficulty is the naming of a specific clone, selected in a grown cultivar because of some particular growing value, such as yield, but without having any distinguishing characteristics or for a clone which is free from a certain disease, such as virus.

My suggestion is that the problem can be solved by using clone names applied to the cultivar name, e.g. Prunus cerasus 'Stevnsbær' cl. Viki.

For seed produced ornamental plants for landscaping, the word seed source, ss., or the Danish equivalent, frøkilde fk. is suggested.

The local geographical locality is suggested as a name for seed source collected in the natural habitat.

Seed produced on selected material, is suggested to follow the same principles as used for cultivars, e.g. Rosa carolina ss. Inda.
