USPP28138P3 - Raspberry plant variety named ‘Enrosadira’ - Google Patents

Abstract

The red raspberry cultivar ‘Enrosadira’ was found in Trentino (Italy). The new cultivar is a primocane fruit-bearing variety producing two crops per year, wherein the fruits ripen on current season's cane in the middle of July and on previous season's cane in the beginning of June. The resulting fruits are conical and brilliant light red with a very good taste.

Description

BACKGROUND OF THE NEW VARIETY

The present invention concerns a new and distinct cultivar of red raspberry, botanical taxon Rubus idaeus L., hereinafter referred to by the cultivar name ‘Enrosadira’.

The new cultivar ‘Enrosadira’ was discovered in 2004 at Faver (Cembra Valley, Province of Trento, Region Trentino—Italy) and has been asexually reproduced by root cutting since 2008. The new variety ‘Enrosadira’ was produced by pollination of varieties T44L04 ‘Lagorai’ (female parentage)×T35L04 (male parentage). The new cultivar was found to be stable and its distinctive characteristics have been transmitted without change through succeeding (more than 98%) asexual propagations.

SUMMARY OF THE INVENTION

The most outstanding and distinguishing characteristics of the new ‘Enrosadira’ cultivar are briefly reported hereunder:

• • primocane fruit-bearing raspberry plant;
  • brilliant light red fruit colour and good flavour;
  • large, conical, and firm berries;
  • fruit having a very good shelf-life;
  • tolerance to raspberry pests and diseases.

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

BRIEF DESCRIPTION OF THE DRAWINGS

The new red raspberry cultivar ‘Enrosadira’ is illustrated by the accompanying drawings, which are color photographs showing typical specimens of the new variety. The photographs are of ‘Enrosadira’ raspberry two year old plants.

DETAILED DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of the new raspberry variety ‘Enrosadira’.

The performance of the new cultivar for retention of its distinctive characteristics was evaluated through successive asexual propagations by root cutting at Faver (Cembra Valley, Province of Trento, Region Trentino—Italy) under conditions of temperature ranging from −8° C. in winter in an open greenhouse to 32° C. in summer in a closed greenhouse. The plants were grown in a peat substrate as soil.

A plant assessment was performed for four years.

The general characteristics of the new variety ‘Enrosadira’ are: upright canes, strong vigor, adapted to the medium-high winter chill conditions of Northern Italy, and very good root system. The floral bloom is simple with short laterals; the blooming begins in summer on the current year's shoots and in the spring season on the previous year's canes.

The ‘Enrosadira’ is a very early primocane fruit-bearing variety with fruit production beginning in early summer (June in Northern Italy) and lasting until autumn (September in Northern Italy). In autumn, the fruit production is small compared to early summer.
