USPP25636P3 - Raspberry plant named ‘Lagorai Plus’ - Google Patents

Abstract

The new raspberry variety ‘Lagorai Plus’ was obtained by open pollination of hybrid raspberry plant Tulameen at Faver (Cembra Valley, Province of Trento, Region of Trentino, Italy). The new plant is a primocane variety producing two crops per year, wherein the fruits ripen on current season's cane in late autumn and on previous season's cane in mid-summer. The production of autumn is negligible when in summer is very high. The resulting fruits are conical and strong red in coloration.

Description

Genus and species: Rubus idaeus L.

Variety denomination: ‘Lagorai Plus’.

BACKGROUND OF THE NEW VARIETY

A new and distinct red raspberry plant (botanically known as Rubus idaeus L.) hereinafter referred to by the name ‘Lagorai Plus’ is disclosed. The new variety ‘Lagorai Plus’ was obtained by free pollination of Tulameen individual raspberry plants.

The crossing for the new plant was created in 2003 at Faver (Cembra Valley, Province of Trento, Region Trentino, Italy) and it has been subject to selection on year 2005 and then asexually reproduced repeatedly by root cutting since introduction in 2007. The characteristics of the new plant have been found stable and have been transmitted without change through succeeding (more than 6) asexual propagations.

SUMMARY OF THE INVENTION

The most outstanding and distinguishing characteristics of the ‘Lagorai Plus’ plant are hereunder reported.

• • Primocane raspberry plant, but is more interesting growing the variety as floricane;
  • Good fruit colour and flavour;
  • Large and firm berries;
  • Good tolerance to pests and diseases.

The new plant 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 plant ‘Lagorai Plus’ 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 illustration of this character by conventional photographic procedures. The photographs are of plants that are two years old.

FIG. 1 shows the fruit size, shape and colour at ripening.

FIG. 2 is a view of raspberry plants showing, in particular, typical distribution of fruit.

FIG. 3 shows both the ripe and immature fruit size, shape and leaf morphology.

DETAILED DESCRIPTION

The following detailed description set forth the distinctive characteristics of the new variety ‘Lagorai Plus’. The performance of the new plant for retention of its distinctive characteristics has been evaluated through successive asexual propagations by root cutting in the Applicant's setting at Vigolo Vattaro (Province of Trento, Region Trentino, Italy) under controlled conditions of temperature (minimal temperature 15° C. and maximal temperature 28° C.) in greenhouse. The growing was the out of soil using peat as substrate.

The canes have general upright habit and very strong vigour, and require support; the new variety is adapted to medium-high winter chill conditions, such as northern Italy, and has very good root system.

The plant ‘Lagorai Plus’ is a primocane variety with a very low autumn production, while highly productive in summer. Therefore the variety is grown as floricane.

The plant assessment was performed for 3 years.

  Comparison with Commercial Plants

‘Lagorai Plus’ differs from the commercial variety ‘Glen Moy’ in that ‘Lagorai Plus’ is as vigorous plant with strong red firm fruit that ripens from late September to early November and allows a late harvest, while ‘Glen Moy’ is a medium vigorous plant with deep yellowish pink fruit that ripens from mid-September to late October.

The new plant ‘Lagorai Plus’ is similar to the commercial variety ‘Glen Moy’; however, there are several differences as shown in Table 1.
