Abstract

A new and distinct apple tree (Malus domestica) named ‘Bella Rosa’. ‘Bella Rosa’ is a whole plant mutation of the variety ‘Cripps Pink’ and is distinguished by very early full pink-red color over the entire surface of the fruit, its spreading to drooping habit, and its solid flush color pattern.

Description

Latin name of the genus and species:
Botanical classification: Malus domestica.
Variety denomination: The new apple tree variety denomination is ‘Bella Rosa’.
BACKGROUND OF THE VARIETY:
The present invention is a new and distinct cultivar of apple tree botanically known as Malus domestica and referred to by the cultivar name ‘Bella Rosa’. ‘Bella Rosa’ was discovered as a naturally occurring whole plant mutation in a commercial orchard planting of the variety ‘Cripps Pink’ (U.S. Plant Pat. No. 7,880).
‘Bella Rosa’ was first observed in mid-March in Dover, Tasmania, Australia in 2013, where it was distinguished by its very early pink-red color over the entire fruit surface, even in shaded areas of the tree. ‘Bella Rosa’ is further distinguished from its parent by its solid flush pink-red color and high levels of fruit anthocyanin at 40 days after full bloom. ‘Bella Rosa’ is also distinguished from its ‘Cripps Pink’ parent by its drooping habit.
Asexual reproduction of the ‘Bella Rosa’ was carried out by bud grafting in 2014 and trees of the ‘Bella Rosa’ were planted for additional observation at Lucaston, Tasmania, Australia. ‘Bella Rosa’ has since been fruited through successive asexually propagated generations at Lucaston, Tasmania, Australia and has been observed to remain true to type with the distinguishing characteristics retained through successive generations of asexual reproduction.
BRIEF DESCRIPTION OF THE VARIETY
‘Bella Rosa’ is primarily distinguished from its parent ‘Cripps Pink’ by its very early full pink-red color over the entire surface of the fruit and its solid flush color pattern with its very high levels of fruit anthocyanin on young fruitlets at 40 days after full bloom. ‘Bella Rosa’ is further distinguished by its spreading to drooping habit in comparison to its parent ‘Cripps Pink’ and other similar commercial varieties. These and other distinguishing characteristics are set forth in the tables below.
Under similar growing conditions in Tasmania, Australia, under commercial practice, ‘Bella Rosa’ compares to its parent ‘Cripps Pink’ as described in Table 1 below:
