Raspberry plant named ‘DrisRaspSeven’

[0001] Genus and species: Rubus idaeus L.

[0002] Variety denomination: ‘DrisRaspSeven’.

[0003] The present invention relates to a new and distinct raspberry variety designated ‘DrisRaspSeven’ and botanically known as Rubus idaeus L. This new raspberry variety was discovered in Santa Cruz, Calif. in August 2005 and originated from a cross between the proprietary female parent raspberry plant ‘Driscoll Cardinal’ (U.S. Plant Pat. No. 14,903) and the proprietary male parent raspberry plant ‘Driscoll Maravilla’ (U.S. Plant Pat. No. 14,804). The original seedling of the new variety was first asexually propagated at a nursery in Santa Cruz, Calif. ‘DrisRaspSeven’ was subsequently asexually propagated and underwent further testing at a nursery in Santa Cruz, 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] Plant Breeder's Rights for this variety have not been applied for. ‘DrisRaspSeven’ has not been made publicly available or sold more than one year prior to the filing date of this application.

[0005] The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Santa Cruz, Calif.:

• • [0006] 1. Self-fruitful plant; and
  • [0007] 2. Large, bright red berries.

[0012] The following detailed descriptions set forth the distinctive characteristics of ‘DrisRaspSeven’. The data which define these characteristics is based on observations taken in Santa Cruz, Calif. from 2005 to 2011. 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. ‘DrisRaspSeven’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisRaspSeven’ was taken from six-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.
