Abstract

A new and distinct apple variety is described. The variety results from selection among a population of seedlings derived from crossing the apple varieties known as ‘Braeburn’ (not patented) and ‘Royal Gala’ (U.S. Plant Pat. No. 4,121). The fruit of the apple tree of this new variety has an attractive appearance characterised by its striped colour pattern and is notable for its excellent eating quality post-storage. The new variety matures for harvest between the parent varieties and has been named ‘Scifresh’.

Description

BACKGROUND OF THE INVENTION
The invention described herein is a new variety of apple tree (Malus domestica). The new variety was selected from a population of seedlings derived from crossing the apple varieties ‘Braeburn’ (not patented) and ‘Royal Gala’ (U.S. Plant Pat. No 4,121). The cross was made in 1985 on trees at Goddard Lane, Havelock North, Hawkes Bay, New Zealand. The new variety was determined to be distinct from the parent varieties ‘Braeburn’ and ‘Royal Gala’, as well as the sibling varieties ‘Scigold’ (not patented) and the variety ‘Mariri Red’ (U.S. Plant Pat. No. 11,604), and ‘Sweetie’ (not patented), by the following characteristics:
‘Braeburn’: ‘Scifresh’ has an earlier harvest season by at least a week, smaller fruit size, and the fruit shape is globose rather than conical, while fruit colour is a lighter red.
‘Royal Gala’: ‘Scifresh’ has a later harvest season, firmer flesh, and longer storage life.
‘Scigold’: ‘Scifresh’ fruit colour is red striped (whereas ‘Scigold’ is yellow-green), and has firmer flesh.
‘Sweetie’: ‘Scifresh’ has a later harvest season, more globose shape, and smaller fruit size.
‘Mariri Red’: ‘Scifresh’ has an earlier harvest season, being mature one week before ‘Braeburn’, whereas ‘Mariri Red’ is mature one week after Braeburn. ‘Scifresh’ has bright red striped fruit (75% coverage of greyed-red stripes over red on a yellow background), whereas ‘Mariri Red’ has dark red blushed fruit (almost 100% coverage of greyed-purple (R.H.S.C.C. 187B) blush on a yellow-green (R.H.S.C.C. 150C) background).
The new variety has been named ‘Scifresh’. Asexual propagation by budding shows that the unique combination of characteristics of the variety come true to form and are established and transmitted through succeeding propagation. In order to obtain true-to-type clones of the initial plant, the breeders asexually propagated plants by budding dormant buds from the original seedling onto MM.106 rootstock. The plants were asexually reproduced at Goddard Lane, Havelock North, Hawkes Bay, New Zealand.
SUMMARY OF THE INVENTION
The new variety produces fruit with an attractive striped colour pattern and is notable for its excellent eating quality post-storage.
