USPP37126P2 - Rubus plant named ‘BWPRASP03’ - Google Patents

Abstract

A new cultivar of Rubus hybrid plant named ‘BWPRASP03’ that is characterized by its fruit production on primocanes, by its high primocane fruit yields, its early cropping profile, its medium red fruits that are consistently large in size throughout the season, its very good extended shelf life, by its fruit that is easy to pick with low adherence to the plug, its primocanes that are upright, moderately branched and have large leaflets, and its sweet fruit with relatively low acidity.

Description

Botanical classification: Rubus hybrid.

Cultivar designation: ‘BWPRASP03’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2024/1607 filed on Jul. 8, 2024, under 35 U.S.C. 119(f), the entire contents of both applications which are incorporated by reference herein. This application is also related to United Kingdom Plant Variety Office (UPOV) Application No. 18/121 filed on Oct. 16, 2024. The information for the plant breeders' rights applications was received directly from the Inventors.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of raspberry plant, botanically thought to be of hybrid origin with Rubus idaeus and other species in its ancestry. ‘BWPRASP03’ will be referred to hereinafter by its cultivar name, ‘BWPRASP03’. ‘BWPRASP03’ is a new red raspberry plant grown for the fresh fruit market.

‘BWPRASP03’ arose from an on-going breeding program conducted by the Inventors. ‘BWPRASP03’ arose from a cross made in Spring 2019 in Faversham, Kent, United Kingdom between an unnamed and an unpatented proprietary plant in the Inventors' breeding program; designated as accession code “JAH-V2” as the female parent, and patented variety ‘PWPRASP01’ (U.S. Plant Pat. No. 32,721) as the male parent. The new cultivar was selected in the winter of 2020 to 2021 in Cartaya, Huelva, Spain as accession code “PCR-W2” from the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by one of the Inventors by root cuttings in Cartaya, Huelva, Spain in spring of 2021. Asexual propagation of the new cultivar by root cuttings and terminal stem cuttings 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 ‘BWPRASP03’ as a new and unique cultivar of Rubus.

• • 1. ‘BWPRASP03’ exhibits fruit production on primocanes.
  • 2. ‘BWPRASP03’ exhibits high primocane fruit yields.
  • 3. ‘BWPRASP03’ exhibits an early cropping profile.
  • 4. ‘BWPRASP03’ exhibits medium red fruits that are consistently large in size throughout the harvest season.
  • 5. ‘BWPRASP03’ exhibits a very good extended shelf life.
  • 6. ‘BWPRASP03’ exhibits fruit that is easy to pick with low adherence to the plug.
  • 7. ‘BWPRASP03’ exhibits primocanes that are upright, moderately branched and have large leaflets.
  • 8. ‘BWPRASP03’ exhibits sweet fruit with relatively low acidity.

The female parent of ‘BWPRASP03’ differs from ‘BWPRASP03’ in having fruit that is yellow in color with less coherent drupelets, less firm drupelet skin, less shelf life, less sweet tasting fruit and more difficult to pick. The male parent of ‘BWPRASP03’ differs from ‘BWPRASP03’ in having fruit that is lighter red in color with larger drupelets, more thorns that are larger, smaller leaves that are less glossy, and a later cropping profile with a much lower primocane fruit yield. ‘BWPRASP03’ 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 ‘BWPRASP03’ in having lower fruit yields, a later cropping profile, smaller fruit throughout the season, indents on the druplets (‘BWPRASP03’ druplets are smooth), canes with more anthocyanin coloration with larger leaflets, and less density of thorns on the peduncle and pedicel. ‘Autumn Glory’ differs from ‘BWPRASP03’ in producing fruit that is much smaller in size with a later cropping profile, is darker in color, much harder to pick, and exhibits a reduced shelf life.
