Apple tree named ‘Lady Laura’

Abstract

A new apple variety distinguished by the amount and intensity of over-color of the fruit and the earlier coloration of the fruit.

Description

Latin name of the genus and species of the plant claimed: Malus domestica.

Variety denomination: ‘Lady Laura’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of apple tree named ‘Lady Laura.’ The new tree resulted from a spontaneous limb sport mutation of ‘Cripps Pink’ (U.S. Plant Pat. No. 7,880). The ‘Cripps Pink’ tree containing the limb sport of the new variety was discovered growing in a cultivated area in Borenore NSW, Australia.

BRIEF SUMMARY OF THE INVENTION

The ‘Lady Laura’ variety is distinguished from other apple varieties due to the following unique combination of characteristics: the amount and intensity of over color of the fruit, and the earlier coloration of fruit in comparison to ‘Cripps Pink’.

Asexual reproduction of this new variety by budding and grafting shows that the foregoing characteristics come true to form, are firmly fixed, and are established and transmitted through succeeding propagations. The initial asexual reproduction of the new cultivar was performed in New South Wales, Australia.

Certain characteristics of this variety, such as growth and color, may change with changing environmental conditions (such as light, temperature, moisture, nutrient availability, or other factors). Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations are made with reference to The Royal Horticultural Society (R.H.S.) Colour Chart.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a photograph showing typical fruit of the new variety.

FIG. 2 is a photograph showing typical fruit of the new variety as well as the fruit cut in half.

FIG. 3 is a photograph showing typical leaves of the new variety.

The accompanying color photographs shows typical specimens of the fruit and leaves of this new apple tree variety and depict the color as nearly true as is reasonably possible to make the same in a color illustration of this character. It should be noted that colors may vary, for example due to lighting conditions at the time the photograph is taken. Therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from the photograph alone.
