Abstract

A new and distinct apple tree named ‘MAC12’ having fruit notable for its attractive radiant red appearance, crisp and refreshing texture, excellent storage and long shelf life.

Description

Latin name: Malus domestica Borkh.

Variety denomination: ‘MAC12’.

BACKGROUND AND SUMMARY OF THE INVENTION

The new apple tree ‘MAC12’ was created in the course of a planned breeding program carried out at Hawke's Bay, New Zealand. ‘MAC12’ originated in as a seedling from the open pollination of unreleased breeding selection ‘PROP2’ (seed parent, unpatented) by an unknown pollen parent. Initially given the breeder reference ‘R5.2T12’ and subsequently designated ‘MAC12’, the variety was selected in 2009 as a single plant from among a population of seedlings derived from the seed parent. Asexual propagation of the variety was first carried out in Hawkes Bay, New Zealand in 2017 by grafting onto ‘MM106’ rootstock (not patented). The variety has since been observed over a number of asexually propagated generations, and has been found to remain true to type. ‘MAC12’ is distinguished from its seed parent ‘PROP2’ by the shape of the fruit at harvest maturity, the form of the fruit stalk, and the overall tree vigor and predominant cropping habit.

Fruit shape	Obloid	Globose
Fruit stalk	Short, thick	Medium

Predominant cropping habit	Spur bearing	Mix of spurs and shoots

‘MAC12’ is distinguished from ‘Scired’ (not patented) and ‘Cripps Pink’ (U.S. Plant Pat. No. 7,880) by the following characteristics:

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following detailed botanical description is based on observations of three-year-old trees on ‘M9’ rootstock (not patented) made during the 2024 growing season at Hawke's Bay, New Zealand. All colors are described according to The Royal Horticultural Society Colour Chart (Sixth edition 2015; 2019 reprint). It should be understood that the characteristics described will vary somewhat depending upon cultural practices, climatic conditions, and can vary with location and season.
