Abstract

A new primocane raspberry variety named ‘Evita’ having good fruit colour and flavour, great and firm berries, and good tolerance to pests and diseases is disclosed.

Description

Genus and species: Rubus idaeus L.

Variety denomination: ‘Evita’.

BACKGROUND OF THE NEW VARIETY

A new and distinct variety of red raspberry (botanically known as Rubus idaeus L.) hereinafter referred to by ‘Evita’ is disclosed. The new variety ‘Evita’ was obtained from the cross by seedling of individual raspberry plants of the varieties ‘Dolomia’ (mother parent) and ‘Erika’ (father parent).

The crossing for the new variety occurred in year 2007 at Vigolo Vattaro (Trento, Trentino—Italy) and it was subjected to selection in year 2009 and then tested since year 2011. The characteristics of the new variety have been found stable and have been transmitted without change through succeeding (more than 5 years) asexual propagations by root cutting.

Plant breeder's rights were applied for with the European Union on May 14, 2012. ‘Evita’ has not been made publicly available.

SUMMARY OF THE INVENTION

The most outstanding and distinguishing characteristics of the ‘Evita’ variety are hereunder reported.

    • Primocane raspberry plant;
    • Good fruit colour and flavour;
    • Great and firm moderate reddish orange berries;
    • Good tolerance to raspberry pests and diseases.

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.

DETAILED DESCRIPTION

The following detailed description sets forth the distinctive characteristics of the new variety ‘Evita’. The performance of the new variety for retention of its distinctive characteristics has been evaluated through successive asexual propagations by root cutting in the Applicant's setting at Vigolo Vattaro (Trento, 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 type using peat as substrate.

The new variety presents a general habit with upright canes, strong vigor and a very good roots system. It is adapted to medium winter chill conditions such as those of northern Italy. Furthermore, the new variety has high productivity in autumn.

The plant assessment was performed for 3 years.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETY

‘Evita’ differs from the parental varieties in that:

    • the harvest is anticipated of about 7 days respect to the parent variety ‘Erika’;
    • the crop is about 20% higher than the parent variety ‘Erika’;
    • the fruit at ripening is greater and has a more brilliant colour than the parent variety ‘Dolomia’.

The similarities of new variety ‘Evita’ with the commercial variety ‘Polka’ are shown in Table 1.
