Guidelines for Applications

The Purpose of the Trials

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, without neglecting our ancestors' achievements, as an old Chinese adage goes.
