Raspberry plant named ‘DrisRaspEight’

[0001] Genus and species: Rubus idaeus L.

[0002] Variety denomination: ‘DrisRaspEight’.

[0003] 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.

[0004] The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Santa Cruz County, Calif.:

• • [0005] 1. Self-fruitful plant; and
  • [0006] 2. Medium-sized, glossy berries.

[0012] 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^nd edition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.
