USPP32030P3 - Raspberry plant named ‘Titania’ - Google Patents

Abstract

A new a primocane raspberry cultivar named ‘Titania’ which produces berries which are of a very large size with a good colour and flavour is disclosed. The new cultivar has the advantages of producing two crops per year, where the fruits mainly ripen on current season's cane in autumn.

Description

Genus and species: Rubus idaeus L.

Variety denomination: ‘Titania’.

BACKGROUND OF THE NEW VARIETY

A new and distinct cultivar of red raspberry (Rubus idaeus L.) hereinafter referred to by the cultivar denomination ‘Titania’ is disclosed. The new variety ‘Titania’ was obtained from the controlled cross between the varieties ‘Vajolet Plus’ (mother plant) (U.S. Plant Pat. No. 25,573) and the pollen of a wild mountain raspberry plant (father plant) (not patented).

The crossing for the new cultivar occurred in year 2009 in Altopiano della Vigolana (Trento-Italy) and it was subjected to selection in 2010, and successively tested until 2017. The characteristics of the new cultivar have been found stable and have been transmitted without change through succeeding (more than 7 years) asexual propagations by root cutting.

Plant breeder's rights were applied for with the European Union on Jan. 18, 2018. ‘Titania’ has not been made publicly available.

SUMMARY OF THE INVENTION

The most outstanding and distinguishing characteristics of the cultivar ‘Titania’ are hereunder reported.

• • Primocane raspberry plant;
  • Very vigorous and healthy plant;
  • Very large fruit size;
  • Good fruit colour and flavour.

The new variety produces two crops per year and the fruits mainly ripen on current season's cane in autumn.

The new variety can be propagated by: the use of suckers produced in a spawn-bed, root cutting and use of tissue culture techniques. The root cutting is to be preferred.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The new red raspberry cultivar ‘Titania’ is illustrated by the accompanying photographs showing typical specimens of the new variety in colour as true as reasonably possible to make the same colour illustrations of this character by conventional photographic procedures. The photographs are of plants that are from four to six months old.

FIG. 1 is a view showing the raspberry plant with growing fruits. The upright and tall plants with very vigorous lateral shoots, mainly present on the apical part of the plant, can be appreciated.

FIG. 2 is a view showing the leaf upper and lower surfaces.

FIG. 3 is a view showing the plant primocane internode length, cane colour and thorns.

FIG. 4 is a view showing the ripe fruit size and shape.

DETAILED DESCRIPTION

The following detailed description set forth the distinctive characteristics of the new variety ‘Titania’. The performance of the new cultivar for retention of its distinctive characteristics has been evaluated through successive asexual propagations by root cutting in the Applicant's setting at Altopiano della Vigolana, Trentino Region (Italy) under natural conditions in plastic covered high tunnel. The growing was in soilless conditions using coir as substrate.
