DESCRIPTION OF THE PREFERRED EMBODIMENTS

A detailed description of this new apple variety follows, with color terminology being given in accordance with the Munsell hue color chart, except where the color is obvious and described in color terms of ordinary dictionary significance.

A. Genus and species: Malus pumila Mill.

B. Name: Benifuji.

C. Type/Market Class: Fuji variety of apple tree.

The tree has been asexually reproduced by grafting and trees resulting from such asexual reproduction are true to the type of the original tree in all distinguishing characteristics.

D. Breeding history of the variety:

1. Purpose of breeding.--To produce an excellent dessert apple variety.

2. Crossing.--Fuji.times.Unknown.

3. Process of breeding.--Mr. Tsuneo Murakami, No. 2, Shinzo Nagane, Gonohe cho, Sannohe gun, Aomori Prefecture, crossed Fuji and an unknown in 1977. After 2 years, he selected one seedling distinguished by the features of a glossy leaf and late sprouting in 2000 seedlings, and grafted it on the seedling and Maruba rootstock. In 1986, the original tree and the tree based on the seedling bore their first crops. The fruit ripened early in the season and exhibited good eating and storage quality. The tree of this variety was transplanted for sparse planting and protection to other orchards of the breeders in April 1986.

E. Trials: In 1986, the original tree (10 years old) and the tree based on seedling (8 years old) bore 4 fruit and 50 fruit respectively. However, the tree based on Maruba never bore any fruit. In 1987, 40 fruit were picked on the tree based on the seedling.

F. General characteristics:

1. Fruit.--Round to oblong, 250 g (on seedling rootstock) slightly larger than known early maturing varieties. The color is a scarlet stripe on greenish yellow ground color. Dots on the fruit skin are much smaller than Tsugaru variety. Flesh is juicier and firmer than other early maturing varieties. The variety is sweeter (Brix 12.3, PH 3.7) than Kitanosachi variety and has a good eating quality.

2. Harvest time.--The variety is picked August 30 through September 2 (on seedling rootstock) at origin (Aomori Prefecture, Japan). This is 5 days before the Kitanosachi variety and 15-20 days before the Tsugaru variety.

3. Storage.--The fruit can be stored one month in cold storage at Aomori Prefecture, Japan. Vigor of the tree is weak, resembling Tsugaru variety.

4. Blooming date.--The typical blooming date is midseason. That is, at the same time as Fuji or one to two days earlier than Fuji.

G. Detailed characteristics:

1. Tree.--The tree formed as depicted is easily trained to a central leader habit with few, well-spaced scaffold branches having strong attachment to the main stem at angles approaching about 80.degree..

H. Characteristics distinguishable from other varieties:

The variety is distinguished from the Kitanosachi variety by having less fruit skin russet, but resembles Fuji, in coloring, good eating quality and early maturing time.

I. Breeding and propagation-purebred variety:

Propagation.--Hybrid variety. Vegetative propagation

J. Main use of the variety: Dessert and processing apple.

K. Suggestion for growing: Pruning and training of the variety is relatively easy because of few spinal shoots. Productivity appears on many shoots. Cultivation is considered the same as for popular apple varieties.

The pollination requirements and uniformity of productivity from year-to-year are similar to Jonathan.

Claims
