Abstract: This invention relates to a new and distinct variety of raspberry plant named `DrisRaspTwo` which is primarily characterized by medium-sized, medium-red fruit that mature to a dark red color and having an early bud burst, is disclosed.
Claim: I claim:

1. A new and distinct cultivar of raspberry plant as described and shown herein.
Description: Genus and species: Rubus idaeus L.

Variety denomination: `DrisRaspTwo`.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct raspberry cultivar designated `DrisRaspTwo` and botanically known as Rubus ideaus L. This new raspberry variety was discovered in Santa Cruz, Calif. in May 2004 and originated from a crossbetween the female parent raspberry plant `Driscoll Cardinal` (U.S. Plant Pat. No. 14,903) and the proprietary male parent raspberry plant `W776.1` (unpatented). The original seedling of the new cultivar was asexually propagated by stolons or tissueculture, at a nursery in Santa Cruz, Calif. `DrisRaspTwo` was subsequently asexually propagated and underwent further testing at a nursery in Santa Cruz, Calif. for five years. The present invention has been found to be stable and reproduce true totype through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Santa Cruz, Calif. 1. Medium-sized, medium-red fruit that mature to a dark red color; and 2. Having an early bud burst.

DESCRIPTION OF THE PHOTOGRAPHS

This new raspberry plant is illustrated by the accompanying photographs which show the fruit of the plant as well as the primocanes; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. Thephotographs are of plants that are 2 years 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 (from left to right, from top to bottom) a flower bud, an immature fruit, an immature fruit, a mature fruit, the fruit plug, and immature fruit.

DESCRIPTION OF THE NEW VARIETY

The following description of `DrisRaspTwo` is based on observations taken from the 2005 to 2009 growing seasons in Santa Cruz, Calif. This description is in accordance with UPOV terminology. Color designations, color descriptions, and otherphenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions. `DrisRaspTwo` has not been observed under all possible environmental conditions. Colorterminology follows The Royal Horticultural Society Colour Chart, London (R.H.S.) (2001 edition).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

`DrisRaspTwo` differs from the female parent `Driscoll Cardinal` (U.S. Plant Pat. No. 14,903) in that the time of bud burst for `DrisRaspTwo` is early, while the time of bud burst for `Driscoll Cardinal` is late. The number of fruit perlateral (primocane) for `DrisRaspTwo` is 30, while the number of fruit per lateral for `Driscoll Cardinal` is 19. Additionally, `DrisRaspTwo` has pubescence on the primocane prickles, while `Driscoll Cardinal` does not.

`DrisRaspTwo` differs from the proprietary male parent `W776.1` (unpatented) in that the fruit of `DrisRaspTwo` is more tart than the fruit of `W776.1`.

`DrisRaspTwo` differs from the commercial variety `DrisRaspOne` (U.S. Plant Pat. No. 19,656) in that the time of bud burst for `DrisRaspTwo` is early, while the time of bud burst for `DrisRaspOne` is late. `DrisRaspTwo` has larger fruit(length is 3.14 cm and width is 2.97 cm) than `DrisRaspOne` (length is 2.94 cm and width is 2.70 cm). Additionally, the titratable acidity (expressed as a percentage of citric acid) for `DrisRaspTwo` is 11.1, while the titratable acidity for`DrisRaspOne` is 15.3.
