Abstract

A new variety of crab apple tree, which I call "Doubloons", has large white double flowers, a generally round habit of growth with upright spreading dense branches and yellow fruit. The new variety is resistant to apple scab.

Description

DESCRIPTION

The present invention relates to a new and distinct variety of flowering crab apple tree which I have named Doubloons.

My new variety originated out of a breeding program as a cross of Malus `Spring Song`×(M. `Dorothea`×M. `Wintergold`). My attention was first directed to this plant because it combined disease resistant foliage with large, double, white flowers. In comparison, other crab apple trees of the same species growing in the same area were moderately or severely susceptible to apple scab. My new variety exhibited good resistance to this disease. In addition, the flowers of my new variety appeared large in comparison to other cultivars having double or semi-double white or pinkish white flowers.

I observed my new variety for a number of years growing in a cultivated area on my Falconskeape farm in Medina, Ohio. My observations have confirmed that my variety is a distinct and unusual cultivar. Subsequent asexual propagation of my variety by budding under my direction at the nursery of J. Frank Schmidt & Son Co. in Boring, Oreg., and observation of the resulting progeny has proven the characteristics of my new variety to be fixed. Furthermore, these observations have confirmed that my new variety represents a new and improved variety of flowering crab apple tree, as particularly evidenced by the following unique combination of characteristics, which have proven firmly fixed, are outstanding therein, and which distinguish it from all other varieties of this species of which I am aware:

1. Generally rounded habit of growth with upright spreading dense branches;

2. Large white blooms which are fully double;

3. Yellow fruit; and

4. High resistance to apple scab.

The accompanying photographs depict the color and size of the blooms and fruit of my variety, as well as the shape of the tree, as nearly true as is reasonably possible to make the same in a color illustration of this character.

FIG. 1 is a color photograph of flowers of the tree of the present invention;

FIG. 2 is a color photograph of a tree of the present invention generally showing its rounded form and dense upright branches; and

FIG. 3 is a color photograph of fruit on the tree of the present invention.

The blooms of my malus "Doubloons" variety differ from those of its parent cultivars in the following manner:

"Spring Song"--Flowers are single, white

"Wintergold"--Flowers are single, white

"Dorothea"--Flowers are rose pink to crimson, double.

The following comparison chart shows how my new variety of tree differs in some respects from other flowering crab apple cultivars having double or semi-double white or pinkish white flowers:
