Apple tree Hidala

Abstract

The new and distinct variety of apple tree is a mutation of the braeburn apple tree (an unpatented new zealand variety). The fruit of the apple tree of this new variety has an attractive appearance characterized by its bright red color. The new variety has been name Hidala.

Description

SUMMARY OF THE INVENTION

The new variety which is a mutation of the Braeburn variety (an unpatented New Zealand variety) was found by us in February 1981. It was in the form of a single limb mutation growing in our orchard at Hastings, New Zealand. The new variety was distinguishable from Braeburn because of the red color of its fruit. We first performed asexual reproduction of the fruit in October 1983 when we grafted bud-wood onto MM106 root stock. The new variety has been named the Hidala variety. Asexual propagation shows that the unique combination of characteristics and distinctive color come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawings show typical specimens of the foliage and fruit of the new variety as depicted in colors as nearly true as is reasonably possible to make the same in a color illustration of this character. In the drawings:

FIG. 1 is close-up view of five apples of the variety.

FIG. 2 is a more distant view showing details of the tree.

FIG. 3 is a sectional view of two halves of one fruit of the variety.

FIG. 4 is a side by side comparison of fruit of the new variety Hidala (on the left) with a fruit of prior variety Braeburn (on the right).

DETAILED DESCRIPTION OF THE DISCLOSURE

The following is a detailed description of our new variety with color terminology in accordance with the Munsell Notation except where general color terms of ordinary dictionary significance are clearly in turn intended by the context.

The specimens described were grown at our property in Hastings, New Zealand. The observations were made in the 1988/1989 season on trees which were four years old at the time and in the 1989/1990 season on trees which were five years old at the time.

The fruit ripened for eating toward mid-season. Specifically, the fruit ripened 14 days earlier than Granny Smith variety apples and 7 days later than Red Delicious.

Over-color.--High percentage of over-color of skin; red (5R 4/6--Munsell Notation) streaked; weak russet about stem cavity.

Flesh: Juicy; firm; white (10 Y 8/3--Munsell Notation); weak browning of flesh (one hour after cutting stainless steel blade).

Texture.--Fine.

Flavour.--Medium sweetness; weak acidity.

Quality.--Excellent.

Core:

Distinctness of core line in cross-section (medium through locules).--Weak.

Aperture of locules in cross-section.--Open.

Central cavity (in cross-section).--Present.

Sinus: Closed.

Seeds: Medium sized; brown (approximately 5 YR 5/8--Munsell Notation).

Use: Market; dessert.

Keeping quality: Good.

Resistance to:

Insects.--Good.

Diseases.--Good.

The main distinguishing characteristic between the Hidala variety and the Braeburn variety has to do with the color of the fruit. By Munsell Notation, the Braeburn variety fruit has a background of 10 Y 7/6 with a red over color of 7.5 R 4/6. The Braeburn fruit skin color is thus a bright fleck orange red expressed as a positive stripe over an over washed color of blush over 40 to 50% of the fruit surface area. The Hidala skin color is 50 to 70% block red overlaid by an even darker fleck. As can be seen by referring to FIG. 4, the Hidala apple has an overall more reddish appearance compared to the Braeburn apple which exhibits a much greater proportion of the background color.

Hidala has been observed to have less vigor and vegetation than Braeburn trees growing in similar properties. Hidala and Braeburn bloom at the same time.

The apples have been picked from Hidala at the same time or earlier than the picking of Braeburn apples which in New Zealand is in the range of from 19 March to 21 April. Like Braeburn, the Hidala tree tends to be biennial bearing.

Claims

1. A new and distinct variety of apple tree which is a mutation of the braeburn variety (an unpatented new zealand variety) substantially as shown and described, characterized by the bright red color of the fruit which extends substantially over the entire surface of the fruit.
