Abstract

A new and distinct variety of raspberry plant named ‘DrisRaspEight’ particularly distinguished by having a self-fruitful plant that bears medium-sized, glossy berries, is disclosed.

Description

Genus and species: Rubus idaeus L.

Variety denomination: ‘DrisRaspEight’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct raspberry variety designated ‘DrisRaspEight’ and botanically known as Rubus idaeus L. This new raspberry variety was discovered in Ventura County, Calif. in October 2008 and originated from a cross between the proprietary female parent raspberry plant ‘Driscoll Estrella’ (U.S. Plant Pat. No. 19,137) and the proprietary male parent raspberry plant ‘DrisRaspFour’ (U.S. Plant Pat. No. 22,731). The original seedling of the new variety was first asexually propagated via tissue culture at a nursery in Santa Cruz County, Calif. in 2008. ‘DrisRaspEight’ was subsequently asexually propagated and underwent further testing at a nursery in Santa Cruz County, Calif. for seven 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.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Santa Cruz County, Calif.:

- 1. Self-fruitful plant; and
- 2. Medium-sized, glossy berries.

DESCRIPTION OF THE PHOTOGRAPHS

This new raspberry plant is illustrated by the accompanying photographs which show cane, leaves, flowers and fruit of the new plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are eleven 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 at various stages of development.

FIG. 4 shows close-up views of typical fruit at various stages of development.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘DrisRaspEight’. The data which define these characteristics is based on observations taken in Santa Cruz County, Calif. from 2008 to 2014. 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. ‘DrisRaspEight’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisRaspEight’ was taken from eleven-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^ndedition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘DrisRaspEight’ differs from the proprietary female parent ‘Driscoll Estrella’ (U.S. Plant Pat. No. 19,137) in that ‘DrisRaspEight’ is more vigorous and has larger fruit of better quality than ‘Driscoll Estrella’.

‘DrisRaspEight’ differs from the proprietary male parent ‘DrisRaspFour’ (U.S. Plant Pat. No. 22,731) in that ‘DrisRaspEight’ has better quality and brighter colored fruit with a higher yield than ‘DrisRaspFour’.

‘DrisRaspEight’ differs from commercial variety ‘Driscoll Maravilla’ (U.S. Plant Pat. No. 14,804) in that ‘DrisRaspEight’ has strongly glossy, medium firm fruit having an easy adherence to the plug, whereas ‘Driscoll Maravilla’ has medium glossy, firm fruit having a medium adherence to the plug.
