Claims
What is claimed is:
1. A new and distinct variety of raspberry plant designated
`DrisRaspThirteen` as shown and described herein.
Description
Latin name: Botanical classification: Rubus idaeus L.
Varietal denomination: The varietal denomination of the claimed
variety of raspberry plant is `DrisRaspThirteen`.
BACKGROUND OF THE INVENTION
Raspberries are the edible fruit of a multitude of plant species in
the genus Rubus of the rose family. Most raspberry species are in
the subgenus Idaeobatus. Raspberry plants are perennial plants with
woody stems. Many of the most important modern commercial red
raspberry cultivars derive from hybrids between R. idaeus and R.
strigosus. Recent breeding has resulted in cultivars that are
thornless and more strongly upright, not needing staking.
Both the red and the black raspberry species have albino-like
pale-yellow natural or horticultural variants. Fruits from such
plants are called golden raspberries or yellow raspberries. Most
pale-fruited raspberries commercially sold in the eastern United
States are derivatives of red raspberries. Yellow-fruited variants
of the black raspberry are sometimes grown in home gardens. Despite
their dissimilar appearance, golden raspberries retain the
distinctive flavor of their respective red or black species.
An individual raspberry fruit is made up of around 100 drupelets,
each of which contains a juicy pulp and a single central seed. A
raspberry bush can yield several hundred berries a year. Unlike
blackberries and dewberries, a raspberry has a hollow core once it
is removed from the receptacle.
Raspberries are traditionally planted in the winter as dormant
canes, but planting plugs produced by tissue culture is also
common. Additionally, the long cane production method consists of
growing canes for one year in cold climates where the bud break is
early, and then transplanting the canes to warm climates where they
quickly flower and can produce an early season crop. A very
vigorous crop, raspberries spread well and can be considered
invasive, using extended underground shoots (also known as suckers
or basal shoots) that can develop roots and individual plants.
Raspberries are a popular fruit that are recognized for their
antioxidants, high fiber, and as a good source of vitamin C.
Raspberry fruit is typically consumed as fresh fruit, individually
quick frozen (IQF) fruit, or in prepared foods, such as purees,
juices, jellies, jams, grocery items, baked goods, and snack
foods.
Raspberry is an important and valuable commercial fruit crop,
widely grown in all temperate regions of the world. Accordingly,
there is a need for new varieties of raspberry plant. In
particular, there is a need for improved varieties of raspberry
plant that are stable, high yielding, and agronomically sound.
SUMMARY OF THE INVENTION
In order to meet these needs, the present invention is directed to
an improved variety of raspberry plant. In particular, the
invention relates to a new and distinct variety of raspberry plant
(Rubus idaeus L), which has been denominated as
`DrisRaspThirteen`.
Raspberry plant variety `DrisRaspThirteen` was discovered in Santa
Cruz County, Calif. in June of 2010 and originated from a cross
between the proprietary female parent raspberry plant
`DrisRaspThree` (U.S. Plant Pat. No. 23,477) and the proprietary
male parent raspberry plant `RA101.1` (unpatented). The original
seedling of the new variety was first asexually propagated by
tissue culture at a nursery in Santa Cruz County, Calif. in
2010.
`DrisRaspThirteen` was subsequently asexually propagated via tissue
culture and root cuttings, and underwent further testing at a farm
in Santa Cruz County, Calif. for six years (2010 to 2015). The
present invention has been found to be stable and reproduce true to
type through successive asexual propagations via tissue culture and
root cuttings.
`DrisRaspThirteen` exhibits the following distinguishing
characteristics when grown under normal horticultural practices in
Santa Cruz County, Calif.: 1. Medium cane height; 2. High number of
current season's canes; 3. High percentage of flowering primocanes;
4. Medium-sized fruit with high length-to-width ratio; and 5.
Moderate resistance to powdery mildew.
`DrisRaspThirteen` was selected for its large fruit size and higher
yield on smaller plants.
BRIEF DESCRIPTION OF THE DRAWINGS
This new raspberry plant is illustrated by the accompanying
photographs, which show fruit of the plant, as well as the
primocanes, flowers, and leaves. The colors shown are as true as
can be reasonably obtained by conventional photographic procedures.
The photographs are of plants that are from eight months old to
eighteen months old.
FIGS. 1A and 1B illustrate both the lower surface (FIG. 1A) and the
upper surface (FIG. 1B) of plant leaves of variety
`DrisRaspThirteen`.
FIG. 2 illustrates typical flowers and fruit of variety
`DrisRaspThirteen` at various stages of development.
FIG. 3 illustrates section of a young cane with prickles of variety
`DrisRaspThirteen`.
DETAILED BOTANICAL DESCRIPTION
The following descriptions set forth the distinctive
characteristics of `DrisRaspThirteen`. The data that define these
characteristics are based on observations taken in Santa Cruz
County, Calif. from 2010 to 2015. 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. `DrisRaspThirteen` has
not been observed under all possible environmental conditions. The
botanical description of `DrisRaspThirteen` was taken from
eight-month-old to eighteen-month-old plants. The indicated values
represent averages calculated from measurements of several 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.

COMPARISONS TO PARENTAL AND COMMERCIAL RASPBERRY VARIETIES
`DrisRaspThirteen` differs from the proprietary female parent
`DrisRaspThree` (U.S. Plant Pat. No. 23,477) in that
`DrisRaspThirteen` has a shorter cane height but higher number of
current season's canes than `DrisRaspThree`. Additionally, plants
of `DrisRaspThirteen` produce fruits on the primocane that are
smaller in size and produce a higher percentage of flowering
primocanes as compared to `DrisRaspThree`.
`DrisRaspThirteen` differs from the proprietary male parent
`RA101.1` (unpatented) in that `DrisRaspThirteen` has a longer cane
height than `RA101.1`. Moreover, plants of `DrisRaspThirteen`
produce flowers that are bigger and fruits that are larger in size
as compared to `RA101.1`.
`DrisRaspThirteen` differs from the commercial variety `Driscoll
Maravilla` (U.S. Plant Pat. No. 14,804) in that plants of
`DrisRaspThirteen` produce a higher percentage of flowering
primocanes than `Driscoll Maravilla`. Moreover, plants of
`DrisRaspThirteen` produce fruits that are larger in size and have
a higher length to width ratio, and seeds that are lighter in
weight as compared to `Driscoll Maravilla`.
