Latin name: Botanical classification: Rubus idaeus L.
Varietal denomination: The varietal denomination of the claimed variety of raspberry plant is ‘DrisRaspEleven’.
Raspberries are the edible fruit of a multitude of plant species in the genus Rubus of the rose family. Most raspberry species are in the subgenus Idaeobatus. Raspberry plants are perennial plants with woody stems. Many of the most important modern commercial red raspberry cultivars derive from hybrids between R. idaeus and R. strigosus. Recent breeding has resulted in cultivars that are thornless and more strongly upright, not needing staking.
Both the red and the black raspberry species have albino-like pale-yellow natural or horticultural variants. Fruits from such plants are called golden raspberries or yellow raspberries. Most pale-fruited raspberries commercially sold in the eastern United States are derivatives of red raspberries. Yellow-fruited variants of the black raspberry are sometimes grown in home gardens. Despite their dissimilar appearance, golden raspberries retain the distinctive flavor of their respective red or black species.
An individual raspberry fruit is made up of around 100 drupelets, each of which contains a juicy pulp and a single central seed. A raspberry bush can yield several hundred berries a year. Unlike blackberries and dewberries, a raspberry has a hollow core once it is removed from the receptacle.
Raspberries are traditionally planted in the winter as dormant canes, but planting plugs produced by tissue culture is also common. Additionally, the long cane production method consists of growing canes for one year in cold climates where the bud break is early, and then transplanting the canes to warm climates where they quickly flower and can produce an early season crop. A very vigorous crop, raspberries spread well and can be considered invasive, using extended underground shoots (also known as suckers or basal shoots) that can develop roots and individual plants.
Raspberries are a popular fruit that are recognized for their antioxidants, high fiber, and as a good source of vitamin C. Raspberry fruit is typically consumed as fresh fruit, individually quick frozen (IQF) fruit, or in prepared foods, such as purées, juices, jellies, jams, grocery items, baked goods, and snack foods.
Raspberry is an important and valuable commercial fruit crop, widely grown in all temperate regions of the world. Accordingly, there is a need for new varieties of raspberry plant. In particular, there is a need for improved varieties of raspberry plant that are stable, high yielding, and agronomically sound.
In order to meet these needs, the present invention is directed to an improved variety of raspberry plant. In particular, the invention relates to a new and distinct variety of raspberry plant (Rubus idaeus L), which has been denominated as ‘DrisRaspEleven’.
Raspberry plant variety ‘DrisRaspEleven’ was discovered in Whatcom County, Wash. in August of 2009 and originated from a cross between the proprietary female parent raspberry plant ‘V312.1’ (unpatented) and the proprietary male parent raspberry plant ‘RB721.1’ (unpatented). The original seedling of the new variety was first asexually propagated via cuttings in 2009.
‘DrisRaspEleven’ was subsequently asexually propagated via root cuttings, and underwent further testing at a farm in Whatcom County, Wash. for seven years (2009 to 2015), The present invention has been found to be stable and reproduce true to type through successive asexual propagations via root cuttings.
‘DrisRaspEleven’ exhibits the following distinguishing characteristics when grown under normal horticultural practices in Whatcom County, Wash.:
‘DrisRaspEleven’ was selected for its large fruit, red fruit color, and its ability to withstand mechanical harvesting.
This new raspberry plant is illustrated by the accompanying photographs, which show fruit of the plant, as well as a cane, flowers, and leaves. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are two years old.
The following descriptions set forth the distinctive characteristics of ‘DrisRaspEleven’. The data that define these characteristics are based on observations taken in Whatcom County, Wash. from 2009 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. ‘DrisRaspEleven’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisRaspEleven’ was taken from two-year-old plants. The indicated values represent averages calculated from measurements of several 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, 2ndedition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.
‘DrisRaspEleven’ differs from the proprietary female parent ‘V312.1’ (unpatented) in that ‘DrisRaspEleven’ produces fruit that is larger, sweeter, and has a brighter red color than that produced by ‘V312.1’. Additionally, ‘DrisRaspEleven’ produces plants that are higher yielding than ‘V312.1’ plants.
‘DriRaspEleven’ differs from the proprietary male parent ‘RB721.1’ (unpatented) in that ‘DrisRaspEleven’ produces fruit with a sweeter flavor than that produced by ‘RB721.1’. Additionally, ‘DrisRaspEleven’ produces plants that are higher yielding than ‘RB721.1’ plants.
When ‘DrisRaspEleven’ is compared to the commercial variety ‘Willamette’ (unpatented), ‘DrisRaspEleven’ produces fruit with a sweeter processing flavor than fruit produced by ‘Willamette’.
When ‘DrisRaspEleven’ is compared to the commercial variety ‘Meeker’ (unpatented), ‘DrisRaspEleven’ produces fruit with a larger size than that of ‘Meeker’.
