USPP36645P2 - Olive tree named ‘I 74’ - Google Patents

Abstract

The new and distinct variety of olive tree ‘I 74’ is provided. The variety can be distinguished by its outstanding features of medium vigor, high yield, and high oil content.

Description

Latin name of the genus and species: Botanical classification:

• • a. Genus—Olea.
  • b. Species—europaea.

Variety denomination: The new olive tree claimed is of the variety denominated ‘I 74’.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a new and distinct variety of olive tree, which has been given the variety denomination of ‘I 74’.

Background of the Related Art

Olive oil continues to increase in popularity. Accordingly, there is a continuing need to develop new and improved olive oils to meet the increased demand for use in various food types and in cooking. Many olive varieties are self-sterile. As a result, there is a need for the development of new olive varieties which are self-pollination and produce a high yield of new and improved olive oil for commercialization.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of olive tree, which has been given the variety denomination of ‘I 74’. ‘I 74’ is intended for use for oil production.

The new olive tree variety is a selection resulting from a sexual cross of olive trees at Córdoba, Spain in 2008 involving a seed parent known as ‘Arbosana’ (unpatented) and a pollen parent known as ‘Koroneiki’ (unpatented).

The selection was subsequently evaluated for 10 years at Córdoba, Spain.

Asexual reproduction of the new variety by cutting propagation since 2014 at Córdoba, Spain has demonstrated that the new variety reproduces true to type with all of the morphological characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

Selection criteria were medium vigor, adaptation to hedge cultivation, high yield, and high oil content.

Plants of the new variety differ from plants of the seed parent ‘Arbosana’ primarily in characteristics of the fruit. ‘I-74’ has a more elongated fruit than ‘Arbosana’ and ripens 1-3 weeks earlier. Plants of the new variety differ from plants of the pollen parent ‘Koroneiki’, primarily in production and vigor. ‘I 74’ has less alternation in production (more equal production between years) and 15-30% lower vigor than ‘Koroneiki’. This new variety stands out for its high production compared to its parents ‘Arbosana’ and ‘Koroneiki’. Additionally, this variety is notable for its medium vigor. This variety produces fruit with medium weight which are colored dark violet at full maturity.

Plants of the new variety differ from the varieties mentioned in co-pending application Ser. No. 18/445,927 (for Olive Tree Variety Named ‘I 24’) and Ser. No. 18/445,919 (for Olive Tree Variety Named ‘I 72’) as shown in Table 1 below:
