RUBUS ARCTICUS L. SUBSP. X STELLARCTICUS A NEW ARCTUC RASPBERRY

The Latin name is validly published according to the International Code of Botanical Nomenclature (Larsson, 1980. Stafleu et al., 1972).

From a Swedish parent, R. a. L. ssp. arcticus, the new berry has the typical, exquisite arcticus aroma. An American parent, R. a. L. ssp. stellatus from western Alaska, has given vigour, uniform red colour and flower fragrance.

Two promising clones, 'Anna' and 'Linda' have been released. They must be cultivated together, each clone being self-sterile. 'Anna' and 'Linda' can be distinguished mainly through fruit characteristics. Otherwise it is difficult to distinguish clones within the hybrid.

Field experiments indicate selected clones to be well adapted in southern as well as northern Sweden.

The new arctic raspberry will probably be a speciality item on the market, since its yield is comparatively low, and the berry is firmly attached to the calyx.

Attacks of insects and diseases have been rare.
