Raspberry plant named ‘Sarafina’

Abstract

A new and distinct cultivar of Raspberry plant named ‘Sarafina’, characterized by its upright and somewhat bushy plant habit; freely branching habit; high fruit production; fruits are produced on prior and current seasons' canes; large light red purple-colored conical fruits; pleasant and sweet fruit taste; and good fruit postharvest longevity.

Description

Botanical designation: Rubus idaeus.

Cultivar denomination: ‘SARAFINA’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Raspberry plant, botanically known as Rubus idaeus and hereinafter referred to by the name ‘Sarafina’.

The new Raspberry plant is a product of a planned breeding program conducted by the Inventor in Rossum, Gelderland, The Netherlands. The objective of the breeding program was to develop new Raspberry plants with good fruit quality, productivity, uniformity and postproduction longevity.

The new Raspberry plant originated from a cross-pollination made by the Inventor of a proprietary selection of Rubus idaeus identified as code number 48, not patented, as the female, or seed, parent with Rubus idaeus ‘Advaberimar’, disclosed in U.S. Reissue Pat. No. 46,031 and U.S. Plant Pat. No. 23,916, not patented, as the male, or pollen, parent in 2011. The new Raspberry plant was discovered and selected by the Inventor as a single plant from within the progeny of the stated cross-pollination in a controlled environment in Rossum, Gelderland, The Netherlands in early September, 2012.

Asexual reproduction of the new Raspberry plant by root cuttings in a controlled environment at Rossum, Gelderland, The Netherlands since the spring of 2013 has shown that the unique features of this new Raspberry plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Raspberry have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sarafina’. These characteristics in combination distinguish ‘Sarafina’ as a new and distinct Raspberry plant:

• • 1. Upright and somewhat bushy plant habit.
  • 2. Freely branching habit.
  • 3. High fruit production.
  • 4. Fruits are produced on prior and current seasons' canes.
  • 5. Large light red purple-colored conical fruits.
  • 6. Pleasant and sweet fruit taste.
  • 7. Good fruit postharvest longevity; fruits do not darken in color after harvesting.

Plants of the new Raspberry differ primarily from plants of the female parent selection in number of flowers and fruits produced as plants of the new Raspberry produce more flowers per spray and more fruits per plant of the female parent selection.

Plants of the new Raspberry differ primarily from plants of the male parent, ‘Advaberimar’, in fruit color as plants of the new Raspberry produce lighter-colored fruits than plants of ‘Advaberimar’ selection.

Plants of the new Raspberry can be compared to plants of Rubus idaeus ‘Advabereen’, disclosed in U.S. Reissue Pat. No. 46,041 and U.S. Plant Pat. No. 23,915. In side-by-side comparisons, plants of the new Raspberry differ from plants of ‘Advabereen’ in the following characteristics:

• • 1. Plants of the new Raspberry are not as freely branching as plants of ‘Advabereen’.
  • 2. Fruits of plants of the new Raspberry are heavier in weight and firmer than fruits of plants of ‘Advabereen’.
