Raspberry plant named `PS-1852`
Abstract
This invention relates to a new and distinct variety of
raspberry plant named `PS-1852`. The new variety is primarily
adapted to the growing conditions of the central coast of
California and is characterized by the following: large upright
primocanes, late fall primocane production, early spring floricane
production, large conical berries, with nearly 2/3 of the total
production coming from the floricane. Foliage is strongly concave,
medium green; possessing very strong rugosity, and always
3-foliage. Primocanes have a weak waxy coat, dense thorns, and weak
to medium anthocyanin coloration.

Claims
I claim:
1. A new and distinct raspberry plant known as `PS-1852`, as herein
described and illustrated by the characteristics set forth above.
Description
Latin name of the genus and species of the plant claimed: Rubus
idaeus.
Variety denomination: `PS-1852`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct raspberry
variety designated as `PS-1852`. This new variety is a result of a
controlled cross made by the inventor, Stephen M. Ackerman, in 1995
between raspberry variety `PS-1094` (an unpatented Plant Sciences,
Inc. selection) and raspberry variety `PS-1316` (an unpatented
selection). The variety is botanically known as Rubus idaeus.
The seedling resulting from the aforementioned cross was asexually
propagated by dormant canes in Santa Cruz County, Calif. and was
subsequently selected by the inventor from a controlled breeding
plot in Watsonville, Calif. in 1997. After its selection, the new
variety was further asexually propagated by dormant canes, roots
and non-dormant root shoot cuttings in both Santa Cruz County,
Calif. and San Joaquin County, Calif. The new variety was then
extensively tested over the next several years in fruiting fields
in Santa Cruz County, Calif. This propagation has demonstrated that
the combination of traits disclosed herein as characterizing the
new variety are fixed and remain true to type through successive
generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
`PS-1852` is primarily adapted to the climate and growing
conditions of the central coast of California. This region provides
the necessary year-round temperatures required for it to produce
and maintain a strong vigorous plant and to remain in fruit
production from August through December on primocanes and in the
ensuing year from May through July on the floricanes. The following
traits have been repeatedly observed and are determined to be
unique characteristics of `PS-1852`, which in combination
distinguish this raspberry plant as a new and distinct variety: 1.
Large plant size; 2. Late fall primocane production; 3. Early
spring floricane production; and 4. Large fruit size.
The raspberry varieties that are believed to be most closely
related to the new raspberry variety `PS-1852` are the raspberry
variety `PS-1049` (patented, U.S. Plant Pat. No. PP 10,142), and
the raspberry variety `PS-1703` (patented, U.S. Plant Pat. No. PP
15,151).
In comparison to the similar raspberry varieties `PS-1049` and
`PS-1703`, `PS-1852` differs by the following combination of
characteristics described in Table 1:

BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color photographs illustrate the overall
appearance of typical specimens of the new raspberry variety,
`PS-1852`, at various stages of development as true as reasonably
possible with color reproductions of this type. Color in the
photographs may differ slightly from the color value cited in the
detailed botanical description which accurately describes the color
of `PS-1852`. The depicted plant and plant parts of the new
raspberry variety `PS-1852` were taken in Watsonville, Calif. and
are approximately 7 to 10 months old.
FIG. 1 shows typical primocane plant characteristics taken in the
month of August;
FIG. 2 shows a close-up of typical primocane foliage
characteristics taken in the month of August;
FIG. 3 shows typical primocane field fruiting characteristics taken
in the month of August; and
FIG. 4 shows typical primocane fruit characteristics taken in the
month of October.
DETAILED BOTANICAL DESCRIPTION
`PS-1852` has not been observed under all possible environmental
conditions. The characteristics of the new variety may vary in
detail, depending upon variations in environmental factors,
including weather (temperature, humidity and light intensity), day
length, soil type, and location.
The aforementioned photographs, together with the following
description of the new raspberry variety `PS-1852`, unless
otherwise noted, is based on observations taken during the 2006
growing season in Watsonville, Calif. Primocane measurements and
ratings were taken from plants of `PS-1852` dug from a nursery
located in San Joaquin County, Calif., during the middle of
December, 2005, and planted approximately 3 to 4 weeks later in
Watsonville, Calif. The approximate age of the observed primocane
plants is 7 to 8 months. Floricane measurements and ratings were
taken from the plants of `PS-1852` dug from a nursery located in
San Joaquin County, Calif., during the middle of December, 2004,
and planted approximately 3 to 4 weeks later in Watsonville, Calif.
The approximate age of the observed floricane plants is 16 to 18
months. Yield observations and fruit quality characteristics are
averaged from three years of data collected from the 2004 through
2006 production seasons. Flower measurements and characteristics
are from secondary flowers unless otherwise noted. Fruit
characteristics and measurements are from secondary fruit unless
otherwise noted. Foliage characteristics and measurements are from
3-foliate foliage unless otherwise noted.
Color terminology where noted follows the Munsell Book of Colors,
Munsell Color, Baltimore, Md. (1976).
