Apple tree named ‘FUCIV51’

A new and distinct Malus domestica Borkh. apple tree variety named ‘FUCIV-51’ is a naturally occurring mutation of the Fuji ‘NAGAFU-12’ apple, particularly characterized by a very large area of over color, in particular in warm areas with low day-night thermic excursion; red coloration on most part of the unexposed side of the fruit; and intense purple-red over color.

PRIORITY CLAIM

This application claims priority under 35 U.S.C. §119(f) to European Community Plant Variety Office Application No. 2013/2586 filed Oct. 9, 2013.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of apple tree, botanically known as Malus domestica of the Rosaceae family, and hereinafter referred to by the variety denomination ‘FUCIV51 ’.

The new Malus ‘FUCIV51’ was discovered by the inventors, Michelangelo Leis and Alessio Martinelli, in the summer 2005 as a naturally occurring mutation branch in a block of Fuji apple trees designated as ‘NAGAFU-12’(unpatented), growing in a cultivated area of an orchard in Ferrara, Italy. The tree of the new variety was showing fruits distinctly different in appearance, more intense and diffused red skin surface color, from the fruit of the adjacent Fuji ‘NAGAFU-12’ trees.

Asexual reproduction of the new Malus ‘FUCIV51’ trees started by grafting onto M9 rootstock in February 2009 in a new testing field in S. Giuseppe di Comacchio (Ferrara), Italy. Some trees of Fuji ‘NAGAFU-12’ (unpatented), and Fuji ‘Aztec’ were grafted on M9 rootstocks in the same row and at the same time as ‘FUCIV51’ was first grafted on M9 rootstocks. First fruiting of the ‘FUCIV51’ trees occurred in 2007, and revealed that fruit produced from the ‘FUCIV51’ trees possessed characteristics which clearly distinguished ‘FUCIV51’ from other Fuji apple varieties known to the Inventors. Asexual reproduction of ‘FUCIV51’ 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 ‘FUCIV51’ which in combination distinguish this apple tree as a new and distinct variety from the other Fuji strains:

    • 1. Very large area of over color, in particular in warm areas with low day-night thermic excursion;
    • 2. Red coloration on most part of the unexposed side of the fruit and
    • 3. Intense purple red over color.

In comparison to the parental variety Fuji ‘NAGAFU-12’, ‘FUCIV51’ produces fruit with a more intense and diffused red skin surface color. The two varieties differ primarily in the traits listed in Table 1.

Of the many commercial varieties known to the present inventors, the most similar in comparison to ‘FUCIV51’ is the variety ‘Raku Raku’ (unpatented), in the following characteristics described in Table 2:

 DETAILED BOTANICAL DESCRIPTION

‘FUCIV51’ 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 trees of ‘FUCIV51’ 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 ‘FUCIV51’ 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 ‘FUCIV51’ 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 ‘FUCIV51’ trees that were grown in the apple farm in S. Giuseppe di Comacchio, Ferrara, Italy, from 2009 to 2012. All trees were of cropping maturity. Quantified measurements are expressed as an average of measurements taken from a number of individual trees of ‘FUCIV51’. 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 (London) 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.
