Claims
We claim:
1. A new and distinct variety of raspberry plant named
`DrisRaspSix` as described and shown herein.
Description
Genus and species: Rubus idaeus L.
Variety denomination: `DrisRaspSix`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct raspberry
variety designated `DrisRaspSix` and botanically known as Rubus
idaeus L. This new raspberry variety was discovered in Ventura,
Calif. in February 2004 and originated from a cross between the
proprietary female parent raspberry plant `Driscoll Maravilla`
(U.S. Plant Pat. No. 14,804) and the proprietary male parent
raspberry plant `Driscoll Francesca` (U.S. Plant Pat. No. 14,860).
The original seedling of the new variety was first asexually
propagated at a nursery in Santa Cruz, Calif. `DrisRaspSix` was
subsequently asexually propagated and underwent further testing at
a nursery in Ventura, Calif. for nine years. The present invention
has been found to be stable and reproduce true to type through
successive asexual propagations via tissue culture and root
cuttings.
Plant Breeder's Rights for this variety have not been applied for.
`DrisRaspSix` has not been made publicly available or sold more
than one year prior to the filing date of this application.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing
characteristics of this new variety when grown under normal
horticultural practices in Ventura, Calif.: 1. High productivity;
2. Partially self-fruitful plant; and 3. Medium sized, bright red
berries.
DESCRIPTION OF THE PHOTOGRAPHS
This new raspberry plant is illustrated by the accompanying
photographs which show fruit of the plant as well as the
primocanes. The colors shown are as true as can be reasonably
obtained by conventional photographic procedures. The photographs
are of plants that are six months old.
FIG. 1 shows a section of a young cane with prickles.
FIG. 2 shows both the upper surface and the lower surface of the
plant leaves.
FIG. 3 shows close-up views of typical flowers and fruit at various
stages of development.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `DrisRaspSix`. The data which define these
characteristics is based on observations taken in Ventura, Calif.
from 2003 to 2011. This description is in accordance with UPOV
terminology. Color designations, color descriptions, and other
phenotypical descriptions may deviate from the stated values and
descriptions depending upon variation in environmental, seasonal,
climatic and cultural conditions. `DrisRaspSix` has not been
observed under all possible environmental conditions. The botanical
description of `DrisRaspSix` was taken from six-month-old plants.
Color references are primarily to The R.H.S. Colour Chart of The
Royal Horticultural Society of London (R.H.S.) (2007 edition).
Descriptive terminology follows the Plant Identification
Terminology, An Illustrated Glossary, 2.sup.nd edition by James G.
Harris and Melinda Woolf Harris, unless where otherwise
defined.
