Abstract

The present invention comprises a new and distinct selection of Olea europaea L. (popularly known as the olive tree) hereinafter referred to as Olea europaea cultivar Don Carlo. Olea europaea cultivar Don Carlo exhibits medium plant vigor, erect on average branch structure, greyish green fruit and superior olive oil.

Description

BACKGROUND OF THE INVENTION
Olive oil continues to increase in popularity. 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. As a result, there is a need for the development of new olive cultivars which produce oils yielding superior quality olive oil.
BRIEF SUMMARY OF THE INVENTION
In order to meet these needs, the present invention is directed to a new olive cultivar named Olea europaea cultivar ‘Don Carlo’. The olive cultivar of this invention was obtained by means of mass-selection on a seed population of the Frantoio cultivar derived from self pollination. The plant exhibits medium plant vigor, erect on average branch structure and greyish green fruiting branches. The bark color is greyed-green (code 191/A, according to R.H.S. Colour Chart), upper side foliage colour is greyed-green (code 195/A, according to R.H.S. Colour Chart), lower side foliage colour is greyed-green (code 195/C, according to R.H.S. Colour Chart), opened flower is yellow-green (code 150/D, according to R.H.S. Colour Chart), flower bud color is yellow-green (code 145/C, according to R.H.S. Colour Chart), and seed colour (endocarp) is grey-brown (code 199/D, according to R.H.S. Colour Chart). ‘Don Carlo’ has been asexually reproduced by self-rooting a cutting branch in Garda and Molise, Italy. The plants as asexually reproduced remain true to type.

DESCRIPTION OF THE INVENTION
The present invention concerns an olive variety of medium vigour and generally having an erect branch structure.
According to the International Code of Botanical Nomenclature, the cultivar name chosen is Olea europaea L. cv ‘Don Carlo’.
The present variety has been obtained by means of the mass-selection used, for about 20 years, with a large Olea europaea L. seed population, deriving from embryos obtained by self-pollination of the cultivar Frantoio. Initially subjects with a high rooting aptitude were individually selected and subsequently the vigour of the studied subjects were verifed selecting those having more moderate vigour, once the growth stage was behind the selection regarded the genotypes bearing larger fruit size. Within these, the new genetic line, object of the present description—from the point of view of the average character of the fruit and from its self-pollinating properties, was chosen. The present variety clearly distinguishes itself from all the other known varieties and has homogeneous and stable characteristics. For the constitution of the present variety, the objective was to overcome the self-sterility problem, which recurs in the olive and which in the specific case is accompanied by elevated rooting attitude, early production stage, high productivity, high oil yield. The new genotype gives late ripening, attitude to mechanical harvesting, resistance to cold and to the most common parasites of the olive.
The response of the present variety has been studied through observations repeated for years and in different environments (for about 13 years) in the olive growing areas of Garda and Molise. On the basis of the results, it was possible to ascertain that the present variety possesses excellent agronomic, biological and technological characteristics, which makes this variety one of great value. The resulting plants show an excellent growth both in the nursery and in the field, having moreover, the peculiarity starting from the third year of forming very few sterile branches as the new growths show productive properties.
The distinctive characteristics of this variety are reported in the following description. The described plant was 10 years of age and grown with or without irrigation with 5′×3′ spacing.
Four photographs are attached to the present description of the varieties showing the entire plant, fruiting branches, a series of inflorescences and one showing a fruit bearing branch, leaves, entire and sectioned drupes and stones.
