Description

ORIGIN OF THE VARIETY

The present new variety of nectarine tree was originated by us in our experimental orchard located near Modesto, Calif., as a first generation seedling from a cross between two nectarine seedlings with the field identification numbers 19G850 and 55GA798. The female parent with the identification number 19G850 originated from an open pollinated Ruby Gold Nectarine (U.S. Plant Pat. No. 3,101). The pollen parent with the identification number 55GA798 originated from a second generation cross between Flame Kist Nectarine (non-patented) and a selected nectarine seedling which originated from a cross between an open pollinated Red Grand Nectarine (U.S. Plant Pat. No. 1,060) seedling and Royal Gold Peach (U.S. Plant Pat. No. 2,663). We grew and maintained a large group of these first generation seedlings under careful observation and the present variety which exhibited the distinctive desirable characteristics described above was selected for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

The new and distinct variety of nectarine tree was asexually propagated by budding by us in our experimental orchard located near Modesto, Calif., and shows that such reproductions run true to the original tree and are established and transmitted through succeeding propagations.

SUMMARY OF THE VARIETY

The herein described variety of nectarine tree is of large size, vigorous upright growth and a productive and regular bearer of very large, firm, yellow flesh, freestone fruit with excellent eating quality. The fruit is further characterized by its relative uniform maturity on the tree, a high degree of attractive red skin color and good storage and shipping qualities. In comparison to the Red Grand Nectarine (U.S. Plant Pat. No. 1,060) the fruit of the present variety ripens in approximately the same maturity season but is freestone instead of clingstone, has a higher degree of attractive red skin color, and has heavier production with larger size fruit.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photographic reproductions in color are of typical specimens of the foliage and firm ripe fruit of the present variety of nectarine tree. These illustrations show the upper and lower surface of the leaves, the exterior and sectional view of the fruit, with a fruit being divided in its suture plane to show flesh coloration and a stone remaining in place. The photographic illustrations were taken shortly after the fruit was picked at maturity and the colors are as nearly true as is reasonably possible in a color representation of this type.
