Raspberry plant—Vajolet Plus cultivar

The raspberry plant ‘Vajolet Plus’ was obtained by open pollination of Polka raspberry plants at Faver, (Cembra Valley, Province of Trento, Region Trentino—Italy). The new plant is a promocane variety producing two crops per year, wherein the fruits ripen on current season's cane in late to very late on previous season's cane early to medium. The resulting fruits are broad conical and vivid reddish orange in coloration.

Description

Genus and species: Rubus idaeus L.

Variety denomination: ‘Vajolet Plus’.

BACKGROUND OF THE NEW VARIETY

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

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

SUMMARY OF THE INVENTION

The most outstanding and distinguishing characteristics of ‘Vajolet Plus’ are hereunder reported:

    • Primocane raspberry plant; growing the variety as floricane is to be preferred;
    • Good fruit colour and flavour;
    • Large and firm reddish orange berries;
    • Good shelf life.

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 ‘Vajolet 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 illustrations of this character by conventional photographic procedures.

FIG. 1 is a view showing fruiting rows with the ripe and immature fruits borne on the tips.

FIG. 2 is a view showing the fruit size, shape and colour at ripening.

FIG. 3 is a view showing both the ripe and immature fruit size and shape.

 DETAILED DESCRIPTION

The following detailed description set forth the distinctive characteristics of the new variety ‘Vajolet 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, since 2007. The growing was the out of soil using peat as substrate. The canes have general upright habit and very strong vigour, with very good root system; adapted to lower-medium winter chill conditions such as in southern Italy. Furthermore, the plant has very high productivity in summer and lower productivity in autumn.

The plant assessment was performed for 3 years.

Colour references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (Ed. 2007).

DETAILED BOTANICAL DESCRIPTION

A first assessment of the new plant was performed, in autumn, on a plant freshly planted in April of the same year. Then a second assessment was performed on the same plant at springtime of the following year (i.e. on a one year old plant). The plant observed has the following botanical description.
