Rose rootstock named 'Pronne'

摘要

A new and distinct rose plant is provided which is particularly well suited for service as a rootstock for a rose scion cultivar. More specifically, when so used the scion cultivar exhibits a propensity to yield an increase in biomass and the promotion of faster bud release when compared to the results achieved when the scion cultivar is grown on its own roots or on a standard rootstock, such as ‘Natal Briar’. Both higher production rates combined with improved quality in the scion variety are facilitated. The new rose plant displays an upright growth habit with vigorous growth. Small single pink changing to near white cup-shaped blossoms are formed having five generally heart-shaped petals. Orange reproductive organs are prominently displayed at the centers of the blossoms. Medium green leaflets with finely serrated margins primarily towards the tips of leaflets and a matte upper surface are displayed.

1. A new and distinct rose plant characterized by the following characteristics:
(a) displays an upright growth habit with vigorous growth, (b) forms small single pink changing to near white cup-shaped blossoms having five generally heart-shaped petals with the prominent display of orange reproductive organs at the center of the blossoms, (c) exhibits medium green leaflets with finely serrated margins having a matte upper surface, and (d) when used as a rootstock for a cut rose scion variety exhibits a propensity to yield an increase in biomass and the promotion of faster bud release for the scion variety;substantially as shown and described.
