BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of raspberry plant, botanically of hybrid origin with Rubus idaeus and other species in its ancestry. ‘BWPRASP01’ will be referred to hereinafter by its cultivar name, ‘BWPRASP01’. ‘BWPRASP01’ is a new red raspberry plant grown for the fresh fruit market.
‘BWPRASP01’ arose from an on-going breeding program conducted by the Inventor. ‘BWPRASP01’ arose from a cross made in spring of 2015 in Faversham, Kent, United Kingdom between unnamed and unpatented proprietary plants in the Inventor's breeding program; designated as accession code F2FH-E5 as the female parent and designated as accession code ECP-E1 as the male parent. The new cultivar was selected in Autumn of 2016 in Cartaya, Huelva, Spain as accession code KAP-E4 from the seedlings that resulted from the above cross.
Asexual propagation of the new cultivar was first accomplished by the Inventor by root cuttings in Faversham, Kent, United Kingdom in spring of 2017. Asexual propagation of the new cultivar by root cuttings, terminal stem cuttings, and tissue culture using meristematic tissue has shown that the characteristics of the new cultivar are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘BWPRASP01’ as a new and unique cultivar of Rubus.
- 1. ‘BWPRASP01’ exhibits fruit production on primocanes.
- 2. ‘BWPRASP01’ exhibits consistently large fruit that are light red in color.
- 3. ‘BWPRASP01’ exhibits consistent fruit quality throughout the cropping season.
- 4. ‘BWPRASP01’ exhibits an extended shelf life.
- 5. ‘BWPRASP01’ exhibits easy picking as there is low adherence to the plug and easily accessible through the canopy.
- 6. ‘BWPRASP01’ exhibits early fruit production.
- 7. ‘BWPRASP01’ exhibits firm fruit with low acidity.
- 8. ‘BWPRASP01’ exhibits a versatile cropping schedule as it can be established on different planting dates throughout summer to maintain cropping in autumn and winter in Spain.
‘BWPRASP01’ differs from its female parent in producing fruit earlier in the season, in being easier to pick, in having larger fruits that are less juicy, a longer shelf life, and less lateral branches. ‘BWPRASP01’ differs from its male parent in producing fruit earlier in the season, in being easier to pick, in having larger fruits that are sweeter and juicier with thicker and less glossy skin, and less lateral branches. ‘BWPRASP01’ can be compared to Rubus cultivars ‘Diamond Jubilee’ (U.S. Plant Pat. No. 25,455) and ‘Autumn Glory’ (U.S. Plant Pat. No. 25,952)). ‘Diamond Jubilee’ differs from ‘BWPRASP01’ in producing fruit later in the season, in having thicker canes with more sparse spines and lower anthocyanin intensity, and fruit that is more round to broad conical in shape with skin that is deeper red in color. ‘Autumn Glory’ differs from ‘BWPRASP01’ in producing fruit later in the season, in having slightly thicker canes with lower anthocyanin intensity, and fruit with skin that is dark red in color.
