Description

PRIORITY CLAIM

This application claims priority under 35 U.S.C. §119(f) of the European Community Plant Variety Rights No. 2005/0312 filed Feb. 21, 2005.

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

Variety denomination: ‘CIVG198’.

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 ‘CIVG198’.

The new Malus variety is a product of a planned breeding program conducted by the inventors, Michelangelo Leis, Alessio Martinelli, Gianfranco Castagnoli and Francesco Tagliani in S. Giuseppe di Comacchio (Ferrara), Italy. The objective of the breeding program was to develop a new Malus variety with deep, red skin color, high sugar content, very firm flesh, scab resistance, long storage capacity and long shelf life.

The new Malus variety, ‘CIVG198’, originated from a cross made in a planned, controlled breeding program in S. Giuseppe di Comacchio (Ferrara), Italy. The female parent is Malus domestica Mill. ‘Gala’ (‘Kidd's Orange’בGolden Delicious’ — 1939, patented, U.S. Plant Pat. No. 3,637). The male parent is Malus domestica Mill. ‘Liberty’ (unpatented, ‘Macoun’×Purdue 54-12-1955). ‘CIVG198’ was discovered and selected in 1996 by the inventors as a flowering plant within the progeny of the stated cross in a controlled environment in S. Guiseppe di Comacchio (Ferrara), Italy.

Asexual reproduction of the new Malus variety by budding and grafting as first performed in September, 1996, and then again in September, 1999, 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 ‘CIVG198’ which in combination distinguish this apple tree as a new and distinct variety:

• • 1. Deep red skin color of the fruit;
  • 2. High sugar content;
  • 3. Very firm flesh;
  • 4. Scab resistance;
  • 5. Long storage capacity; and
  • 6. Long shelf life.

In comparison to the parental varieties, ‘Gala’ and ‘Liberty’, ‘CIVG198’ differs primarily in the traits listed in Table 1:

TABLE 1
	Time of maturity
Variety	for consumption	Flesh firmness	Fruit shape
‘CIVG198’	Medium	Very strong	Conic
‘Gala’	Early	Strong	Globose conical
‘Liberty’	Early	Medium	Globose

Of the commercial cultivars known to the inventors, the most similar in comparison to ‘CIVG198’ is the male parental variety ‘Liberty’ as compared in Table 1.

DETAILED BOTANICAL DESCRIPTION

The new Malus variety ‘CIVG198’ 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 ‘CIVG198’ as grown in the apple farm in S. Guiseppe di Comacchio (Ferrara), Italy, under conditions which closely approximate those generally used in commercial practice. The apple farm where ‘CIVG198’ 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 ‘CIVG198’ is grown is sandy, and the soil is treated with manure every year and irrigated with drip irrigation systems. The climate is temperature 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 ‘CIVG198’ trees that were grown in the apple farm in S. Guiseppe di Comacchio (Ferrara), Italy, from 2003 to 2004. All trees were of cropping maturity. Quantified measurements are expressed as an average of measurements taken from a number of individual trees of ‘CIVG198’. 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 (RHS), except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately at 10:00 am in S. Guiseppe di Comacchio (Ferrara), Italy.
