Description

Latin name of the genus and species of the plant claimed: Malus domestica Mill.

Variety denomination: ‘Sinfonia’.

PRIORITY CLAIM

This application claims priority to European Community Plant Variety office application No. 2012/2804 filed Dec. 11, 2012, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of apple tree, botanically known as Malus domestica Mill. of the Family Rosaceae, and hereinafter referred to by the variety denomination ‘Sinfonia’.

The new Malus variety is a product of a planned breeding program conducted by the inventors, Michelangelo Leis, Alessio Martinelli, Francesco Tagliani and Gianfranco Castagnoli in S. Giuseppe di Comacchio (Ferrara), Italy. The objective of the breeding program was to develop new Malus varieties with improved production characteristics, high-quality flavour and aroma and sustainability by increasing the tree's natural resistance. The primary objective of the research program is to selection new apple varieties with natural resistances, in particular to scab.

The new Malus variety ‘Sinfonia’, originated from a cross made in a planned, controlled breeding program in S. Giuseppe di Comacchio (Ferrara), Italy. The female parent is the apple tree variety ‘Co-op 25’ (patented; U.S. Plant Pat. No. 12,323). The male parent is an unpatented, proprietary selection denominated ‘CIVCP-142’. ‘Sinfonia’ was discovered and selected in October 2000 by the inventors as a flowering plant within the progeny of the stated cross in a controlled environment in S. Giuseppe di Comacchio (Ferrara), Italy.

Asexual reproduction of the new Malus variety by budding and grafting was first performed in August 2001 and in the following years in S. Giuseppe di Comacchio (Ferrara), Italy, and has demonstrated that the combination of characteristics as herein disclosed for the new Malus variety are firmly fixed and retained through successive generations of asexual reproduction. The new variety reproduces true to type.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Sinfonia’ which in combination distinguish this apple tree as a new and distinct variety:

    • 1. Bi-colored variety with intense light red overcolor;
    • 2. Big size;
    • 3. Weak vigor, open habit with short branches;
    • 4. High sugar content and
    • 5. Long storage ability.

When compared to plants of the parent varieties, the claimed variety ‘Sinfonia’ differs primarily in the traits listed in Table 1 below:

When compared to plants of the related variety ‘Majesty’ (U.S. Plant patent application Ser. No. 13/986,175), the claimed variety differs primarily in the traits listed in Table 2 below:

Of the commercial cultivars known to the inventors, the most similar in comparison to the new apple tree variety ‘Sinfonia’ is the variety ‘Galaxy’(unpatented). In comparison to the similar variety ‘Galaxy’, ‘Sinfonia’ differs primarily in the traits listed in Table 3 below.

 DETAILED BOTANICAL DESCRIPTION

The new Malus variety ‘Sinfonia’ has not been observed under all possible environmental conditions. The phenotype of the new variety may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe the new Malus variety ‘Sinfonia’ as grown in the apple farm in S. Giuseppe di Comacchio (Ferrara), Italy, under conditions which closely approximate those generally used in commercial practice. The apple farm where ‘Sinfonia’ is grown is situated near the Adriatic sea (44°45′ North, 12° 11′ East) and is zero (0) meters above sea level. The soil of the apple farm where ‘Sinfonia’ is grown is sandy, and the soil is treated with manure every year and irrigated with drip irrigation systems. The climate is temperate continental with high summer temperatures and low winter temperatures.

Unless otherwise stated, the detailed botanical description includes observations, measurements and values based on four (4) year old ‘Sinfonia’ trees that were grown in the apple farm in S. Giuseppe di Comacchio (Ferrara), Italy, from 2008 to 2011 All trees were of cropping maturity. Quantified measurements are expressed as an average of measurements taken from a number of individual trees of ‘Sinfonia’. The measurements of any individual tree, or any group of trees, of the new variety may vary from the stated average.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately at 10:00 am in S. Giuseppe di Comacchio (Ferrara), Italy.

All trees of ‘Sinfonia’, insofar as they have been observed, have been identical in all the characteristics described below.
