The purpose of the trials is to encourage the well-balanced development of rose breeding, in particular the breeding of roses suited to cold, snowy regions, which will thus add to the attraction of the rose garden in Echigo Hillside Park. Special emphasis is placed on fragrance - developing new fragrance, as an old Chinese adage goes, without neglecting our ancestors' achievement.
Breeders both professional and amateur, in Japan and overseas, and also agents (including nurseries) for such breeders
If the applicants are their agents, breeders have to attach a document which states that they entrusted the agents the application for the trials.
The sponsor of the trials shoulders no responsibility on matters concerning the intellectual property rights and/or sales rights of the breeders. If any problems occur, they should all be resolved between the parties concerned. Depending on the situation, awards might be revoked by the sponsor.
Varieties which have never been on the market, or were made available for sale on or after the first of January, 2006.
There is no limitation on the number of varieties the breeder can enter into the trial.
For each variety, four two-to-three years old bare-root trees, either budded, grafted, or self-rooted.
None
The trial is conducted in the trial grounds of National Echigo Hillside Park.
