Abstract

A new and distinct apple tree (Malus domestica Borkh) named ‘Pink Chief’. The new variety is a spontaneous limb mutation of ‘Cripps Pink’ and is distinguished by its highly colored pink-red fruit, weaker vigor and columnar bearing.

Description

Latin name: Malus domestica Borkh.

Variety denomination: ‘Pink Chief’.

BACKGROUND OF THE VARIETY

‘Pink Chief’ is a new and distinct cultivar of apple tree Malus domestica Borkh. This new variety is a spontaneous limb mutation of ‘Cripps Pink’ (U.S. Plant Pat. No. 7,880). ‘Pink Chief’ was first observed in a ‘Cripps Pink’ orchard in Dover, Tasmania, Australia in 2007, where it was distinguished by its highly colored fruit. Asexual reproduction of the new variety was carried out by bud grafting in 2009 and trees of the new variety were planted for additional observation at Lucaston, Tasmania, Australia. It was found that the new variety is also distinguished from its parent by its weaker vigor and columnar bearing. ‘Pink Chief’ has since been fruited through successive asexually propagated generations at Lucaston and has been observed to remain true to type.

BRIEF DESCRIPTION OF THE VARIETY

The new variety claimed herein is primarily distinguished by its intense pink-red fruit color and columnar bearing. These and other distinguishing characteristics are set forth in the tables below.

‘Pink Chief’ is distinguishable from its parent ‘Cripps Pink’ as described in Table 1 below:

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following-detailed botanical description is based on observations made during the 2013 and 2014 growing seasons at Lucaston, Tasmania, Australia of three-year-old trees planted on ‘MM106’ rootstock (not patented). All colors are described according to The Royal Horticultural Society Colour Chart (5^THedition 2007). It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and will 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.
