Abstract

A new raspberry plant named ‘Stella’ particularly distinguished by large fruit for use in fresh market, high brightness fruit; large number of branches after first crop, with a long cane; and good cold tolerance, is disclosed.

Description

Genus and species: Rubus idaeus L.

Variety denominations: ‘Stella’.

BACKGROUND OF THE NEW PLANT ‘STELLA’

The present invention comprises a new and distinct variety of Raspberry, botanically known as Rubus idaeus L, and hereinafter referred to by the variety name ‘Stella’. ‘Stella’ originated from seed of a fruit from an unknown female and an unknown male plant. The seed was found in October 2018 in Applicant's fruit sorting and processing facility in Tarquejo, Huelva, Spain.

In October 2018, seed from the fruit found at Applicant's facility was planted. In October 2018 a plant was selected and named ‘Stella’. ‘Stella’ was first vegetatively propagated by vegetative cuttings in Tarquejo, Huelva, Spain.

SUMMARY OF ‘STELLA’

The following are the most outstanding and distinguishing characteristics of ‘Stella’ when grown under normal horticultural practices in Tarquejo, Huelva, Spain.

- 1. Large fruit for use in fresh market;
- 2. High brightness fruit;
- 3. Large number of branches after first crop, with a long cane; and
- 4. Good cold tolerance.

DESCRIPTION OF THE PHOTOGRAPHS

This new raspberry plant is illustrated by the accompanying photographs from October 2023 of plants grown in Tarquejo, Huelva, Spain. The plants are six months old and grown in a hydroponic system. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.
