PEACH TREE NAMED 'NJ352'

Abstract

A new and distinct peach variety of Prunus persica named ‘NJ352’ is provided. This variety is distinguished from other peach varieties by its unique combination of nonshowy flowers, fruit that ripen in latter part of mid-season, attractive fruit with a yellow-orange ground color, freestone fruit with a juicy, melting texture and moderately acidic flavor, and good production of firm fruit.

NJ352

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of peach tree named ‘NJ352’. Our new tree resulted from crossing ‘D90-9’ as the seed parent with ‘NJ318’ peach tree, as the pollen parent. The new variety differs from seed parent ‘D90-9’ (unpatented) in that the new variety has small, nonshowy flowers and fruit that ripen in the latter part of mid-season, while the seed parent has large, showy flowers and fruit that do not ripen during a typical growing season. The new variety differs from pollen parent ‘NJ318’ (unpatented) in that the new variety has fruit with yellow-orange flesh and moderate acidity, while the pollen parent has fruit with white flesh and low acidity. The resulting tree was selected when growing in a cultivated area as the 162^nd tree in the 101^st row of Block D at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J.

BRIEF SUMMARY OF THE INVENTION

The ‘NJ352’ variety is distinguished from other peach varieties due to the following unique combination of characteristics:

• Attractive round fruit with a slightly depressed apex point.
• Fruit with an attractive yellow-orange ground color.
• Good production of firm fruit.
• Fruit has better than average eating quality.

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) shows that the foregoing characteristics are so reproduced.

The following detailed description concerns the original tree, ‘NJ352’. The original tree and asexual progeny have been observed growing in a cultivated area at the Rutgers Fruit Research and Extension Center 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 factors. 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 (R.H.S.) 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 ‘NJ352’ in late summer bearing typical leaves of the mature foliage.

FIG. 2 is a color photograph of mature fruit of ‘NJ352’ and stones harvested from the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J. on Aug. 25, 2004. Whole fruit are presented in two positions and a transverse cross section to show that the pericarp does not adhere to the pit when the fruit is mature. The stones illustrate the obovoid shape 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 small, nonshowy flowers of ‘NJ352’ observed on a tree at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J. on Apr. 21, 2004.

FIG. 4 is a color photograph of a tree of ‘NJ352’ in early fall that illustrates the spreading growth habit of a tree at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J. on Oct. 27, 2005.

FIG. 5 is a color photograph taken on Oct. 27, 2005 of immature bark of ‘NJ352’ that illustrates color and the moderate density of grey-white bordered, elliptical lenticels on the immature bark.

FIG. 6 is a color photograph taken on Oct. 27, 2005 of mature bark of ‘NJ352’ that illustrates the fairly smooth texture and inconspicuous lenticels of the mature bark.

The colors of and illustration of this type may vary with lighting and other conditions under which conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.
