Abstract

A new and distinct apple tree named ‘PremA047’, the fruit of which is notable for its intense red skin color, low susceptibility to russet, and excellent storage characteristics.

Description

Latin name: Malus domestica.

Variety denomination: ‘PremA047’.

BACKGROUND AND SUMMARY OF THE INVENTION

The new apple tree ‘PremA047’ was created in the course of a planned breeding program carried out at Havelock North, New Zealand. ‘PremA047’ originated as a result of a controlled cross made in 2009 of female parent ‘Scifresh’ (U.S. Plant Pat. No. 13,888) and male parent ‘A174R01T204’ (not patented). ‘PremA047’ was selected as a single plant from among a population of seedlings derived from the parents, and was initially observed for its attractive fruit with intense red skin color and low susceptibility to russet, its harvest timing, and for its excellent storage characteristics. The plant was first asexually propagated by grafting in 2014 at Havelock North, New Zealand, and has since been observed to retain its desirable characteristics and reproduce true to type over a number of asexually propagated generations.

‘PremA047’ is distinguished from parent varieties ‘Scifresh’ and ‘A174R01T204’, and from similar variety ‘Galaxy’ (U.S. Plant Pat. No. 6,955) as set forth in Tables 1, 2 and 3.

BOTANICAL DESCRIPTION OF THE VARIETY

The following detailed botanical description is based on observations of ‘PremA047’ trees on ‘M9’ rootstock (not patented) planted at Havelock North, New Zealand. The trees were 9 years old when described during the 2023-2024 season, having been grown in the nursery for 2-years before field-planting in 2016. 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. Color descriptions are made with reference to The R.H.S. Colour Chart, 6^thed. (Royal Horticultural Society, London, 2015).

Tree: Trees of ‘PremA047’ are somewhat vigorous, have an upright to spreading growth habit, and tend to be shorter and more compact than ‘Galaxy’ Gala (U.S. Plant Pat. No. 6,955) and ‘CABp Fuji’ (U.S. Plant Pat. No. 17,914), while the trunk of ‘PremA047’ has a cross-sectional area similar to both varieties, as detailed in Table 4.
