Claims
We claim:
1. A new and distinctive cultivar of raspberry plant, substantially
as shown and described.
Description
Latin name of the genus and species of the plant claimed: The
variety is botanically identified as Rubus idaeus L.
BACKGROUND OF THE INVENTION
The new cultivar of raspberry plant was developed from the
hybridization of the selection of `R652.1` (an unpatented variety)
as the seed parent with the selection `R709.1` (an unpatented
variety) as the pollen parent. The parents were crossed in 1997,
whereafter fruit and seed were collected to produce seedlings for
field planting in Watsonville, Calif. in 1997. The new cultivar was
selected from these seedlings in 1998 for its attractive and large
fruit with long pedicels. The new cultivar has been asexually
propagated by in vitro shoot tip culture, root sucker division and
root cuttings at the Cassin Ranch in Santa Cruz county, Calif. and
has been shown to maintain the desired and distinguishing
characteristics after propagation over several generations.
SUMMARY OF THE INVENTION
The present invention provides a new and distinct cultivar of red
raspberry plant named `Driscoll Madonna`. The cultivar is
botanically identified as Rubus idaeus L. The `Driscoll Madonna`
red raspberry plant produces a primocane crop which begins in early
August and continues until early November. The floricane crop
begins in late May and continues until mid to late July. The fruit
of `Driscoll Madonna` is notable for its consistent large size,
uniform shape and long pedicels. The fruit of `Driscoll Madonna`
does not separate easily from its receptacle.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographs show typical specimens of the
primocane fruit, leaves and shoot of the new cultivar, in color as
nearly true as it is reasonably possible to make in color
illustrations of these characteristics.
FIG. 1 is a photograph of `Driscoll Madonna` primocane flower and
fruit in various stages of development.
FIG. 2 is a photograph of `Driscoll Madonna` primocane leaves
showing upper and lower surfaces.
FIG. 3 is a photograph of `Driscoll Madonna` primocane shoot.
DETAILED BOTANICAL DESCRIPTION
The following detailed description of the new raspberry cultivar,
`Driscoll Madonna`, is based upon observations taken of 7 to 17
month old plants and fruit grown in Watsonville, Calif. between
2001 and 2002, and is believed to apply to plants of the `Driscoll
Madonna` cultivar grown in similar conditions of soil and climate
elsewhere.
Throughout this specification, color names beginning with a small
letter signify that the name of the color, as used in common
speech, is aptly descriptive. Color data followed by an
alphanumeric code designates the color according to The R.H.S.
Colour Chart published by The Royal Horticultural Society of
London, England. 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.
Table 1 provides information on the plant and fruit characteristics
of the new cultivar `Driscoll Madonna` compared with
characteristics of the unpatented raspberry cultivar `Heritage`.
Observations of the cultivars were taken under similar
conditions.
The new variety is particularly characterized and distinguished
from other cultivars by its large fruit with excellent fruit
firmness and structure. The fruit is produced on long pedicels and
is difficult to release from the receptacle.
The fruit color of `Driscoll Madonna` is a bright red at harvest.
Fruit of `Driscoll Madonna` does not separate easily from the
receptacle and is of good firmness at harvest. The fruit of
`Driscoll Madonna` is consistent in size and shape throughout the
harvest period. The average plant height is about 240 cm and the
average plant spread is about 50 cm. The pigmentation of the young
shoots is 144B and there were an average of 6 young shoots in the
observed plants of `Driscoll Madonna`. The pedicel color is
144A.
The reproductive organs of `Driscoll Madonna` are variable. The
color of both surfaces of the petals is 155D and there are five
petals per flower. The style color is 157D, the average number of
styles per flower is about 84, the anther color is 155D, and the
average number of anthers per flower is about 97. The number of
petals per flower is five. The color of the seeds of `Driscoll
Madonna` is 161A, the average seed weight is about 1.2 mg, and
there are an average of about 115 seeds per fruit.
The floricane yield of `Driscoll Madonna` is high relative to the
variety `Heritage`. `Driscoll Madonna` is distinguishable from its
pollen parent, selection `R709.1`, by producing larger, firmer
fruit. The new cultivar is distinguished from its seed parent,
selection `R652.1`, by having better flavor.
DISEASE AND STRESS RESISTANCE
Cold tolerance of the new cultivar has not been established. Post
harvest fruit rot resistance is good in comparison over many
selections and varieties.

NUCLEIC ACID FINGERPRINTING
Distinctive patterns of polymorphism can be detected using a
variety of nucleic acid analysis methods. In one non-limiting
example, molecular genetic maps can be produced using random
amplified polymorphic DNA (RAPD) (Williams et al., 1990, "DNA
polymorphisms amplified by arbitrary primers are useful as genetic
markers", Nucleic Acids Res. 18(22):6531-5). Using a variety of
oligonucleotide primers, alone or in combination, RAPD analysis of
Driscoll Madonna and Heritage yielded DNA fragment patterns that
uniquely distinguish each of these genetically distinct
genotypes.
