Abstract

A new and distinct Malus domestica Borkh apple tree variety named ‘CIVM49’ is particularly characterized by resistance to scab. The tree has a very precocious bearing and medium vigor with high and constant productivity. The fruits are very attractive with uniform brilliant deep red color which covers the 80% of the surface. It has a very high eating quality, the flesh is crisp, juicy and tasty with high sweetness and medium-low acidity. Excellent storability and shelf life. Ripening time: 10/15 days after Gala.

Description

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

Variety denomination: ‘CIVM49’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Apple tree, botanically known as Malus domestica Borkh of the Rosaceae family, and hereinafter referred to by the variety denomination ‘CIVM49’.

The new Malus variety is a product of a planned breeding program conducted by the inventors, Michelangelo Leis and Alessio Martinelli, in San Giuseppe di Comacchio, Ferrara, Italy. The objective of the breeding program was to select and develop a new Malus variety with improved productions and sustainability by increasing the tree's natural resistance, very precocious bearing, high and constant productivity. The new varieties had to have very attractive fruits with uniform and deep red color which covers at least the 80% of the surface. The fruit had to have a crispy, juicy flesh with high sweetness and medium-low acidity with high firmness.

The new Malus variety, ‘CIVM49’ originated from a cross made by the inventors in 2000 in San Giuseppe di Comacchio (Ferrara), Italy. The female or seed parent is a patented variety denominated ‘CO-OP39’ (U.S. Plant Pat. No. 16,622). The male or pollen parent is an unpatented variety denominated ‘MITCHGLA’. The new Malus variety ‘CIVM49’ was discovered and selected by the inventors within the progeny of the stated cross in a controlled environment in August 2006 in San Giuseppe di Comacchio (Ferrara), Italy.

Asexual reproduction of the new Malus variety ‘CIVM49’ by budding and grafting was first performed in September 2006 in San Giuseppe di Comacchio (Ferrara), Italy, and has demonstrated that the combination of characteristics as herein disclosed for the new 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 ‘CIVM49’ which in combination distinguish this Apple tree as a new and distinct variety:

- 1. Resistant to scab;
- 2. Very precocious bearing;
- 3. Uniform and deep red color;
- 4. Very high eating quality with high level of sugar; and
- 5. Excellent storability and shelf life.
  In comparison to the parents, ‘CIVM49’ differs primarily in the traits listed in Table 1.

DETAILED BOTANICAL DESCRIPTION

The new Malus variety ‘CIVM49’ 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 Apple tree.

The aforementioned photographs, together with the following observations, measurements and values describe trees of ‘CIVM49’ as grown in the Apple farm in San Giuseppe di Comacchio (Ferrara), Italy, under conditions which closely approximate those generally used in commercial practice. The apple farm where ‘CIVM49’ grows, 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 ‘CIVM49’ is grown is sandy, and the soil is treated with manure every year and irrigated with drip irrigation system. The climate is temperate continental with high summer temperatures and low winter temperature.

Unless otherwise stated, the detailed botanical description includes observations, measurements and values based on seven (7) year old ‘CIVM49’ trees grown in the Apple farm in San Giuseppe di Comacchio (Ferrara), Italy from 2012. Quantified measurements are expressed as an average of measurements taken from a number of ten (10) trees of ‘CIVM49’. Color references are made to The Royal Horticultural Society Color Chart (R.H.S.), 2001 edition, except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately at 10:00 A.M. in San Giuseppe di Comacchio (Ferrara), Italy.
