Nectarine tree, "Mike's Grand"

Abstract

A nectarine tree which very heavily and regularly bears fruit having yellow, semi-freestone flesh and red skin, and which ripens early in the season.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of nectarine tree, denominated by the varietal name "MIKE'S GRAND", and more particularly to such a nectarine tree that is broadly similar to the Star Brite Nectarine Tree (as yet unpatented), but from which it is distinguished by its bearing of fruit having a deeper suture with flesh adhering to its stone on both sutures and having more abundant, coarser fibers.

The subject variety is also closely similar to the May Grand Nectarine Tree (U.S. Plant Pat. No. 2,794) but is distinguished therefrom by its fruit which has flesh more yellow in color and skin somewhat less bright in color, the fruit having a somewhat flatter configuration and ripening two to three days earlier than that of the May Grand.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The subject variety was discovered by us growing in an orchard which we farmed on the East Side Ranch at 16405 East Goodfellow, in the City of Sanger, in the County of Fresno, in the State of Calif. It was found as a single branch growing in an orchard of Early Sungrand Nectarine Trees (unpatented) owned by a partnership comprised of the applicant Richard Peters and CLW and Associates, a New Jersey Corporation. The new variety was asexually reproduced by budding under our supervision and at our instructions at the Bright's Nursery in Le Grand, Calif. Fruit and tree characteristics resulting from this budding proved identical to those of the original sport.

SUMMARY OF THE NEW VARIETY

The instant variety of nectarine tree is characterized by perpetuating the general characteristics of the May Grand Nectarine Tree (U.S. Plant Pat. No. 2,794) in its bearing of early-ripening, semi-freestone fruit, but is distinguished therefrom as to novelty by its greater productivity of fruit having a somewhat flatter shape and which ripens two or three days earlier than that of the May Grand.

The new nectarine tree bears fruit maturing in early June, whose skin attains a color of Maroon (Plate 7-L-7) on a ground color of Doubloom or Roman Ochre (Plate 11-K-10) and whose semi-freestone flesh attains a color of Spanish Yellow (Plate 10-L-7) and has firm, meaty texture with abundant, coarse fibers.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing is a color photograph of four mature nectarines of the subject variety with one of the fruits divided along the suture plane to show the flesh color and stone characteristics, together with a representative twig bearing characteristic leaves.

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

Claims

1. A new and distinct variety of nectarine tree substantially as illustrated and described broadly characterized by its general similarity to the May Grand Nectarine Tree (U.S. Plant Pat. No. 2,794) in its early bearing of fruit having yellow flesh but from which it is distinguished as to novelty by its regular and very productive bearing of fruit having a more completely yellow flesh and a somewhat flatter appearance, ripening two or three days earlier than that of the May Grand variety.
