Abstract

A new and distinct variety of apricot tree which is denominated varietally as "Judy's Delight" and which is somewhat similar to the Katy Apricot Tree (U.S. Plant Pat. No. 4,339), with which it is most closely related, the subject variety characterized as to novelty by producing large fruit which have a light orange skin color and an orange flesh color and which are mature for commercial harvesting and shipment approximately May 15 through May 30 in the San Joaquin Valley of Central California.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to an apricot tree which has been denominated varietally as "Judy's Delight" and more particularly to an apricot tree which produces fruit having an attractive light orange skin color and which ripen for harvesting approximately the same time of the season as the fruit produced by the Katy Apricot Tree (U.S. Plant Pat. No. 4,339) with which it is most closely similar, but from which it is distinguished therefrom and characterized principally as to novelty by producing fruit which are substantially larger in size than that produced by the Katy Apricot Tree and which further exhibits a characteristic skin color which is a lighter shade of orange than that typically displayed by the variety "Katy". In addition, the new variety of Apricot Tree hereof displays noteworthy storage characteristics and has a balanced and pleasant flavor which is uncommon to the variety to which it is most closely similar.

The Katy Apricot Tree (U.S. Plant Pat. No. 4,339) is well known as a producer of early maturing apricots, the fruit of the Katy Apricot Tree characterized by an orange skin color and having a date of maturity for harvesting and shipment during the second and third week of May in the San Joaquin Valley of Central California.

It has long been recognized that it would be desirable to have an apricot tree that somewhat remotely resembles the Katy Apricot Tree (U.S. Plant Pat. No. 4,339) and which further is ripe for commercial harvesting and shipment at approximately the same time of the season but which produces fruit which are substantially larger in size than the fruit produced by the "Katy" Apricot Tree and which further has an attractive light orange skin color and a balanced and pleasant flavor.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The new and distinct variety of apricot tree hereof was discovered in 1981 by the inventors as a chance seedling of unknown parentage growing in the cultivated area of the applicants' property which is located at 4715 South Cherry, in Fresno, Fresno County, Calif. The chance seedling was noted at that time to have desirable characteristics. The inventors observed the chance seedling for several years and scion wood of the new variety was subsequently taken by the applicants in 1985 and grafted into a test seedling which is located on the same property. It has been subsequently determined that this first asexual propagation resulted in progeny being produced that possessed the same distinctive characteristics as the original chance seedling.

SUMMARY OF THE NEW VARIETY

The Judy's Delight variety of Apricot Tree described herein is characterized principally as to novelty by producing fruit which are mature for commercial harvesting and shipment on or about May 15 through May 30, approximately at the same time in the season as the Katy Apricot Tree (U.S. Plant Pat. No. 4,339) with which it is most closely similar, but from which it is distinguished therefrom by producing an apricot which has a distinctive light orange skin coloration and which further has a larger size and a pleasant and well balanced flavor.

Hilum -- Shape.--Roughly oval.

Apex.--Shape -- rounded, and having no point evident. The apex is positioned in an oblique plane with respect to the stone axis.

Sides.--Generally equal, although some variability may be noted from time to time.

Stone surface.--Texture -- moderately rough. One groove appearing in the stone surface is positioned in an attitude roughly parallel to the ventral suture and further is located approximately 4-6 mm. below same. Several irregular pits generally appear in the stone surface and are usually located laterally and just below the apex.

Ventral edge.--Shape -- a thin prominent wing extends from the base to the apex.

Dorsal edge.--Generally -- a deep groove is evident, and extends from the base to mid-suture. This same groove is generally not visible beyond the mid-suture line. The shape of the apical shoulder area of the suture is rounded and numerous small pits are evident. The dorsal edge is distinctive.

Stone color.--Dry -- light brown, (12-G-7).

Tendency to split.--Not observed.

Fruit use: The subject variety "Judy's Delight" is a fresh market apricot for both local and long distance markets.

Storage quality: Good.

Shipping quality: The variety has not been shipped in volume, however, the firm crisp texture of the flesh at commercial maturity strongly indicates that this variety will have noteworthy shipping characteristics.

Although the new variety of apricot tree possesses the described characteristics as a result of the growing conditions prevailing in Fresno County, Calif., in the Central part of the San Joaquin Valley, it is to be understood that variations of the usual magnitude and characteristics incident to growing conditions, fertilization, pruning and pest control are to be expected.
