Summary
In 62 clones of cut roses the numbers of flowering and blind shoots were recorded from February 1975 to January 1976. On average about 25 shoots were harvested per plant, of which 27% were blind. No significant correlation was found between the average numbers of flowering and blind shoots. Progenitors for winter flowering roses should be selected among clones that combine a constant total shoot production with a low percentage of blind shoots.
