Description

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

Variety denomination: ‘ASFARI’.

PRIORITY CLAIM

This application claims priority under 35 U.S.C. §119(f) of the Community plant variety office (CPVO) application No. 2012/0099 filed Jan. 16, 2012.

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 ‘ASFARI’.

The new Malus variety is a product of a controlled breeding program conducted by the inventor(s), Inge De Wit, Hendrik Eyssen, Johan Keulemans, Johan Nicolaï, Els Pauwels and Paul Van Laer, in Rillaar, Belgium. The objective of the breeding program was to develop a new Malus variety with crisp and juicy flesh, as well as good storage capacity and shelf life.

The new Malus variety originated from a cross made by the inventor(s) in 1997 in Belgium. The female or seed parent is the Malus domestica variety designated ‘ELSTAR’ (patented, U.S. Plant Pat. No. 6,450 and Plant Breeder's Rights Nos.: BE 90002, DE APF 00007, FR 10412, GB 900030 and NL APP0060). The male or pollen parent is the Malus domestica variety designated ‘DELCORF’ (registered, Plant Breeder's Rights No. FR 112364). The new Malus variety was discovered and selected by the inventors within the progeny of the stated cross in a controlled environment in 2003 in Rillaar, Belgium.

Asexual reproduction of the new Malus variety by grafting onto rootstocks was first performed in the winter of 2003-2004 in Belgium, 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 ‘ASFARI’ which in combination distinguish this Apple tree as a new and distinct variety:

• • 1. early maturity of fruit;
  • 2. yellow fruit overcolor, sometimes with a slight pink blush;
  • 3. good storability of fruit for its harvest date;
  • 4. aromatic and sweet flavor; and
  • 5. clean skin.

In comparison to the parental varieties, ‘ELSTAR’ and ‘DELCORF’, ‘ASFARI’ differs primarily in the traits listed in Table 1.

DETAILED BOTANICAL DESCRIPTION

The new Malus variety ‘ASFARI’ 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 ‘ASFARI’ as in Rillaar, Belgium, under conditions which closely approximate those generally used in commercial practice.

Unless otherwise stated, the detailed botanical description includes observations, measurements and values based on 6 year old ‘ASFARI’ trees grown in Rillaar, Belgium from 2007 to 2012. Quantified measurements are expressed as an average of measurements taken from a number of trees of ‘ASFARI’. 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.), (4^th edition, 2001), except where general colors of ordinary significance are used. Color values were taken under daylight conditions.
