None

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of apple tree, botanically known as Malus domestica, and hereinafter referred to by the name ‘Gradiyel’.

The new apple variety ‘Gradiyel’ originated from a controlled cross in Hérault, France of Malus domestica ‘Christmas Rose’, (not patented), as the female, or seed parent, with Malus domestica, ‘Gradigold’, (not patented) as the male or pollen, parent. The new Apple tree was discovered and selected by the inventors as a single plant from within the progeny of the stated cross-pollination in a controlled environment in Hérault, France in 1991.

Asexual propagation by grafting was first carried out in Maguio, France. Gradirose has been asexually reproduced by budding and grafting, since 1994 in Hérault, France, and has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations.

SUMMARY OF THE INVENTION

The following characteristics of the new variety have been repeatedly observed and can be used to distinguish ‘Gradiyel’ as a new and distinct cultivar of apple:

    • 1. Semi-upright plant habit.
    • 2. Freely flowering and fruiting habit.
    • 3. Mid-season flowering time.
    • 4. High storage capacity.

‘Gradiyel’ can be compared to Golden Delicious (not patented). Fruit of the new variety is mature and ready for harvest about 20 days after the fruit of Golden Delicious. The fruit skin of ‘Gradiyel’ has more than 50% pink blush whereas the fruit skin of Golden Delicious has less than 10% pink blush. The fruit of ‘Gradiyel’ has a longer shelf life than Golden Delicious, and a sweeter flavor.

 DETAILED BOTANICAL DESCRIPTION

The following detailed botanical description is based on observations of trees planted in 1995, and described during the 2003 and 2004 growing seasons at Hérault, France. Color descriptions refer to The Royal Horticultural Society Colour Chart (1995). It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant, or any group of plants, of the new variety may vary from the stated average.
