Abstract
A new and distinct cultivar of Raspberry plant named ‘Pacific Starlet’ as described and shown herein. ‘Pacific Starlet’ provides very firm berries which detach easily from the receptacle and maintain bright non-darkening color in postharvest cold storage.
Description
BACKGROUND AND SUMMARY

The new raspberry cultivar designated ‘Pacific Starlet’ is shown herein. Botanically known as Rubus idaeus L., ‘Pacific Starlet’ is a primocane-fruiting raspberry that was discovered in a seedling field in May 2010 in Watsonville, Calif. ‘Pacific Starlet’ originated from open pollinated (OP) seed of an unknown variety. An increasing number of patented primocane-fruiting raspberries are discovered using material sourced from OP fruit. One example is the raspberry cultivar ‘Vintage’ (U.S. Plant Pat. No. 24,198), which was derived from open pollinated seed of the patented proprietary variety ‘Isabel’ (U.S. Plant Pat. No. 9,340). Another example is the variety ‘Diamond Jubilee’ (U.S. Plant application Ser. No. 13/694,890), which was derived from open-pollinated fruit that was purchased in a retail store and thought to be the patented proprietary variety ‘Driscoll Maravilla’ (U.S. Plant Pat. No. 14,804).


The present cultivar, ‘Pacific Starlet’, offers significant advantages over the existing, patented primocane-raspberry cultivar ‘Vintage’ (U.S. Plant Pat. No. 24,198). For example, ‘Pacific Starlet’ offers typically firmer fruit than ‘Vintage’. Another example of an existing patented primocane-raspberry is ‘Marcela’ (U.S. Plant Pat. No. 17,819). In contrast to ‘Marcela’, ‘Pacific Starlet’ has much larger fruit, though both are firm and have bright non-darkening color. A third example of an existing, patented primocane-raspberry variety is ‘Pacific Deluxe’ (U.S. Plant Pat. No. 21,074), a previous release from the same breeding program as the present cultivar, ‘Pacific Starlet’. The present cultivar, ‘Pacific Starlet’ is a significant improvement over ‘Pacific Deluxe’ particularly for color; ‘Pacific Deluxe’ tends to darken significantly in postharvest cold storage, whereas ‘Pacific Starlet’ does not darken when picked and cold stored. Other improvements of ‘Pacific Starlet’ over ‘Pacific Deluxe’ include reduced fruit defects, easier fruit detachment, and lower acidity.


Thus, ‘Pacific Starlet’ is a new and distinct primocane-raspberry cultivar that can be identified, among other things, by its bright non-darkening berry color in cold storage, large size, ease of detachment and lower acidity. Further, leaf hue of ‘Pacific Starlet’ is distinct, with an upper color of RHS 137D often flecked with the yellowish-green color RHS 151D.

DETAILED DESCRIPTION

Note: statements of characteristics herein represent exemplary observations of the cultivar herein and will vary depending on time of year, location, annual weather, etc.

  • Cultivar name: ‘Pacific Starlet’
  • Classification:
      • Family.—Rosaceae.
      • Botanical name.—Rubus idaeus.
      • Common name.—Raspberry.
  • Parentage:
      • Female parent (please provide name or code).—Unknown.
      • Male parent (please provide name or code flower).—Unknown. ‘Pacific Starlet’ was first identified in a field with other seedlings in May 2010 at Watsonville, Calif. USA. ‘Pacific Starlet’ was first propagated asexually by crown division in August 2010 in Watsonville, Calif. USA. The crown on the original plant was dug and parted into basal cane pieces (approximately 15 cm long) with root attached and replanted into a selection plot elsewhere on the farm, resulting in a 3-fold increase. In September 2011, two actively growing primocanes were dug (with root attached) and shipped to Lafayette, Oreg. USA, where vegetative material was explanted and established in vitro for micropropagation.
