Genus and species: Rubus idaeus L.
Variety denomination: ‘DrisRaspNine’.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct raspberry variety designated ‘DrisRaspNine’ and botanically known as Rubus idaeus L. This new raspberry variety was discovered in Ventura County, Calif. in February 2011 and originated from a cross between the proprietary female parent raspberry plant ‘RB629.4’ (unpatented) and the proprietary male parent raspberry plant ‘RB629.5’ (unpatented). The original seedling of the new variety was first asexually propagated at a nursery in Santa Cruz County, Calif. in 2011. ‘DrisRaspNine’ was subsequently asexually propagated and underwent further testing at a nursery in Ventura County, Calif. for five 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 Ventura, Calif.:
1. Self-fruitful plant; and
2. Medium-sized, strongly red berries.
DESCRIPTION OF THE PHOTOGRAPHS
This new raspberry plant is illustrated by the accompanying photographs which show fruit, flowers and leaves 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 six months old.
FIG. 1 shows close-up views of typical flowers and fruit at various stages of development.
FIG. 2 shows a close-up view of fruit.
FIG. 3 shows both the upper surface and the lower surface of the plant leaves.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive characteristics of ‘DrisRaspNine’. The data which define these characteristics is based on observations taken in Ventura County, Calif. from 2011 to 2015. 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. ‘DrisRaspNine’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisRaspNine’ 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.) (2015 edition). Descriptive terminology follows the Plant Identification Terminology, An Illustrated Glossary, 2nd edition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.
