Claims
What is claimed is:
1. A new and distinct variety of rose plant of the shrub class,
substantially as herein shown and described.
Description
Classification: The present invention relates to a new Rosa hybrida
shrub of the market class `English Rose`.
Variety denomination: The new plant has the varietal denomination
`AUSoblige`.
CROSS-REFERENCE TO RELATED APPLICATION
The present application claims priority to European CPVO 2016/2384,
filed Sep. 30, 2016.
ORIGIN OF INVENTION
This invention relates to a new and distinct variety of rose plant
suitable for cut-flower production named `AUSoblige`, which was
originated from the cross-pollination of the two `unnamed` and
unpatented seedlings of Rosa hybrida.
BACKGROUND OF THE INVENTION
The primary objective of this breeding was to produce a rose
variety suitable for cut-flower production with large white/creamy
double blooms with around 60 petals forming a loose ruffled rosette
shaped bloom.
SUMMARY OF THE INVENTION
Among the features which distinguish the new variety from others
presently available and commercial rose cultivars known to the
inventor is the following combination of characteristics:
white/creamy blooms; with around 60 petals; and leathery, matt
green leaves.
Asexual reproduction of the new variety by budding as performed at
Bowling Green Lane in Albrighton, Britain shows that the foregoing
and other distinguishing characteristics come true to form and are
established and transmitted through succeeding asexual
propagations. `AUSoblige` may be asexually propagated by budding.
The budding successfully occurred on the plant/rootstock Rosa
inermis for the observed plants.
COMPARISON WITH PARENTS
The maternal and paternal parents of `AUSoblige` are two unnamed
seedlings. The new rose may be distinguished from its maternal
parent, by the following combination of characteristics: the
maternal parent has a pink coloring and fewer petals. The new rose
may be distinguished from its pollen parent, by the following
combination of characteristics: the paternal parent also has a pink
color.
COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR
The closest commercially available cultivars to the new variety are
the `AUSpastor` (U.S. Plant Pat. No. 19,254). The new rose may be
distinguished from the `AUSpastor` by the size of the blooms, which
are smaller (.about.8-9 cm), and have many more petals
(.about.160).
BRIEF DESCRIPTION OF ILLUSTRATION
The accompanying photograph illustrates the new variety and shows
the flowering thereof from bud to full bloom depicted in color as
nearly correct as it is possible to make in a color illustration of
the character. Throughout this specification, color references
and/or values are based upon the Colour Chart of The Royal
Horticultural Society (2001) except where common terms of color
definition are employed.
DESCRIPTION OF THE NEW VARIETY
Observations of budded `AUSoblige` specimens were made at the
nursery at David Austin Roses Limited in Albrighton, Wolverhampton,
United Kingdom. The following description is of 5 year-old rose
plants of the new variety grown in a garden environment in
Albrighton, Britain in the month of May. Phenotypic expression may
vary with environmental, cultural and climatic conditions, as well
as differences in conditions of light and soil.
