Apricot tree ("Tri-Gems")

Abstract

Our new and distinct variety of apricot tree has the following unique combination of desirable features:1. Heavy and regular production of fruit.2. Very firm fruit that will mechanically harvest without excessive bruising.3. Fruit that will maintain excellent texture, shape and appearance after being canned.4. Fruit with good flavor and eating quality both fresh and canned.5. Fruit with a high degree of soluble solids (Average 15% Brix).6. Vigorous, semi-spreading growth.7. Fruit with excellent storage and shipping quality.

Description

ORIGIN OF THE VARIETY

Our new variety of apricot tree was originated by us in the experimental orchard located near Modesto, Calif. It was selected from a number of seedlings grown from the seed of an open pollinated seedling with the field identification number 2W303. The seedling 2W303 originated from a large group of open pollinated Flaming Gold Apricot (U.S. Plant Pat. No. 2,822) seedlings.

ASEXUAL REPRODUCTION OF THE VARIETY

The present variety of apricot tree was asexually reproduced by budding, as performed at Modesto, Calif., and shows that said characteristics described above run true to the original tree and are identical in all respects.

SUMMARY OF THE VARIETY

Our new invention relates to a distinct variety of apricot tree which is of large size, vigorous, semi-spreading growth and a regular and productive bearer of medium size, very firm, yellow flesh, freestone fruit with good flavor and eating quality both fresh and canned. The fruit is further characterized by having high soluble solids (Average 15% Brix) and maintaining excellent texture, shape and appearance after being canned.

PHOTOGRAPHS OF THE VARIETY

The accompanying photographic reproductions show typical specimens of the foliage and fruit of our new apricot variety, with the upper and lower surface of the leaves being illustrated, also an exterior and sectional view of the fruit being shown with the stone remaining in place. These photographs were taken shortly after being picked at maturity (firm ripe) and the colors are as nearly true as reasonably possible in a color representation of this type.
