Raspberry plant named ‘DrisRaspThree’

[0001] Genus and species: Rubus idaeus L.

[0002] Variety denomination: ‘DrisRaspThree’.

[0003] The present invention relates to a new and distinct raspberry variety designated ‘DrisRaspThree’ and botanically known as Rubus idaeus L. This new raspberry variety was discovered in Santa Cruz, Calif. in October 2003 and originated from a cross between the proprietary female parent raspberry plant ‘X146.7’ (unpatented) and the proprietary male parent raspberry plant ‘S858.1’ (unpatented). The original seedling of the new variety was first asexually propagated by tissue culture at a nursery in Santa Cruz, Calif. ‘DrisRaspThree’ was subsequently asexually propagated by root cuttings and underwent further testing at a nursery in Santa Cruz, Calif. for four years. The present invention has been found to be stable and reproduce true to type through successive asexual propagations.

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

• • [0005] 1. High yield;
  • [0006] 2. Good flavor; and
  • [0007] 3. Vigorous growth habit.

[0012] The following description of ‘DrisRaspThree’ 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 other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions. ‘DrisRaspThree’ has not been observed under all possible environmental conditions. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), Fifth Edition (2007).
