Description

ORIGIN OF THE VARIETY

Our new and distinct variety of nectarine tree was originated by us in our experimental orchard located near Modesto, Calif., as a first generation cross between two selected seedlings with the field identification numbers 36ER86 and 9GC175. The maternal parent 36EB86 originated from a second generation seedling that was selected from a cross between May Grand Nectarine (U.S. Plant Pat. No. 2,794) and a peach of unknown parentage. The pollen parent 9GC175 originated from a second generation seedling of a cross between an open pollinated seedling of Early Sun Grand Nectarine (U.S. Plant Pat. No. 1,420) and Royal Gold Peach (U.S. Plant Pat. No. 2,663). A large group of seedlings from this first generation cross were planted and grown under careful observation by us; one such seedling, which is the present variety, having especially desirable fruit characteristics was selected for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

The present new variety of nectarine tree was asexually reproduced by budding, as performed by us, in our experimental orchard located near Modesto, Calif., which shows that all characteristics of the tree and its fruit run true to the original form and are established and transmitted in succeeding propagations.

SUMMARY OF THE VARIETY

The new and distinct variety of nectarine tree is of large size, vigorous, upright growth and is a regular and productive bearer of large size, yellow flesh, clingstone fruit with excellent flavor and eating quality. The fruit is further characterized by having firm flesh, the ability to be shipped to long distance markets, being relatively uniform in size throughout the tree, and in comparison to Early Sun Grand Nectarine (U.S. Plant Pat. No. 1,420) the new variety has the ability to produce more uniform size fruit, to produce fruit without split pits, to produce fruit that holds firm on the tree longer after maturity with a sweeter, more mild subacid flavor and is approximately 2 weeks later in maturity.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

Typical specimens are shown in the accompanying color photographs of the foliage and fruit of the new nectarine variety. The upper and lower surface of the leaves are illustrated with an exterior view of the fruit and a fruit divided in the suture plane to reveal flesh coloration and a stone remaining in place. The photographs were taken shortly after the fruit was picked at maturity (firm ripe) and the colors are as nearly true as is reasonably possible in a color representation of this type.

Claims

1. A new and distinct variety of nectarine tree, substantially as illustrated and described, characterized by its large size, vigorous upright growth, and which is a productive and regular bearer of large size, yellow flesh, clingstone fruit with excellent flavor and eating quality. The fruit is further characterized by holding firm on the tree two weeks after maturity (shipping ripe), having the ability to be shipped to long distance markets and in comparision to Early Sun Grand Nectarine (U.S. Plant Pat. No. 1,420) the new variety has the ability to produce more uniform size fruit which matures approximately 2 weeks later.
