Abstract

A new and distinct peach variety of Prunus persica named ‘NJF18’ is provided. This variety is distinguished from other peach varieties by its unique combination of showy flowers that are medium in width, flat fruit that ripen in early midseason with mottled red over color on an attractive orange ground color, semi-clingstone fruit with a juicy, melting texture and sweet, mild flavor, firm fruit that retain their firmness well and trees with regular, heavy production of large fruit.

Description

Latin name of genus and species of the plant claimed: Prunus persica L.
Cultivar name: ‘NJF18’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of peach tree named ‘NJF18’. Our new tree resulted from crossing ‘H15-20-90258’ (unpatented) as the seed parent with ‘A34-160-782118’ (unpatented) as the pollen parent. The new variety differs from seed parent ‘H15-20-90258’ (unpatented) in that the new variety has flat fruit while the seed parent has round fruit. The new variety differs from pollen parent A34-160-782118′ (unpatented) in that the new variety has pubescent fruit while the pollen parent has glabrous fruit. The resulting tree was selected when growing in a cultivated area as the 72nd tree in the 10th row of Block L at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J.
BRIEF SUMMARY OF THE INVENTION
The ‘NJF18’ variety is distinguished from other peach varieties due to the following unique combination of characteristics:
    • •Flat fruit shape.
    • •Fruit with mottled red over color on an attractive orange ground color.
    • •Good productivity of large fruit,
    • •Sweet, mild flavor.
    • •Melting flesh texture
    • •Very firm fruit that retain their firmness well.
The variety was asexually reproduced at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J. Asexual reproduction of this new variety by budding onto ‘Lovell’ rootstock (unpatented) for several generations shows that the foregoing characteristics are so reproduced.
The following detailed description concerns the original tree, ‘NJF18’. The original tree and asexual progeny have been observed growing in a cultivated area in Cream Ridge, N.J. Certain characteristics of this variety, such as growth and color, may change with changing environmental conditions (such as, light, temperature, moisture, nutrient availability) or other favors. Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations are made with reference to The Royal Horticultural Society (RHS) Colour Chart.
BRIEF DESCRIPTION OF THE DRAWINGS
This new variety is illustrated by the accompanying photographic drawings, depicting the peach tree by the best possible color representation using color photography. Colors are approximate as color depends on horticultural practices, such as light level, fertilization rate, and other conditions and, therefore, the color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.
FIG. 1 is a color photograph taken on Aug. 29, 2005 of a characteristic twig of ‘NJF18’ in late summer bearing typical crinkled and slightly wavy leaves of the mature foliage.
FIG. 2 is a color photograph of mature fruit of ‘NJF18’ and stones harvested in Cream Ridge, N.J. on Aug. 9, 2005. Whole fruit are presented in two positions and a cross section to show that the pericarp adheres partially to the pit when the fruit is mature. The stones illustrate the low to medium height and medium width of the dorsal ridge and the pit grooves on the surface of the stone.
FIG. 3 is a color photograph of a characteristic twig that illustrates the typical flower buds and showy flowers of ‘NJF18’ observed on a tree in Cream Ridge, N.J. on Apr. 9, 2006.
FIG. 4 is a color photograph of a tree of ‘NJF18’ in winter that illustrates the slightly upright growth habit of a tree in Cream Ridge, N.J. on Jan. 2, 2007.
FIG. 5 is a color photograph taken on Jan. 2, 2007 of immature bark of ‘NJF18’ that illustrates color and the low density of elliptical lenticels on the immature bark.
FIG. 6 is a color photograph taken on Jan. 2, 2007 of mature bark of ‘NJF18’ that illustrates the smooth to slightly rough texture of the mature bark.
