Abstract

A new and distinct peach variety of Prunus persica named ‘NJ355’ is provided. This variety is distinguished from other peach varieties by its unique combination of non-showy flowers, fruit that ripen in early-season with an attractive red and greyed-purple over color and orange-white ground color, clingstone fruit with a juicy, firm nonmelting texture and sweet, slightly acidic flavor, and excellent production of firm fruit that maintain their eating quality following cold storage.

Latin name of genus and species of the plant claimed: Prunus persica L.

Variety denomination: ‘NJ355’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of peach tree named ‘NJ355’. Our new tree resulted from open pollination of the seed parent, J19-19-862144. The new variety differs from seed parent J19-19-862144 (unpatented) in that fruit of the new variety ripen approximately 3 weeks earlier and the flesh of the fruit clings to the pit when it is fully ripe. In comparison to the commercial peach variety ‘Sugar May’ (U.S. Plant Pat. No. 8,034), the fruit of the new variety has a lighter red blush, is lower in acidity, and matures approximately 6 days later. The fruit and leaves of the new variety are also more tolerant to bacterial leaf spot than ‘Sugar May’. The resulting tree was selected when growing in a cultivated area as the 44^th tree in the 4^th row of Block H at a fruit research center in Cream Ridge, N.J.

BRIEF SUMMARY OF THE INVENTION

The ‘NJ355’ variety is distinguished from other peach varieties due to the following unique combination of characteristics:

• • Round fruit with a low tendency to split for the season.
  • Attractive fruit with a red and greyed-purple over color and orange-white ground color.
  • Excellent production of very firm fruit that ripen in early-season.
  • Fruit with a good to very good eating quality.

The variety was asexually reproduced at the research 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, ‘NJ355’. The original tree and asexual progeny have been observed growing in a cultivated area at the research 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 (1966 Edition).

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 Jul. 19, 2010 of a characteristic twig of ‘NJ355’ in late summer bearing typical leaves of the mature foliage.

FIG. 2 is a color photograph taken on Jul. 14, 2010 of characteristic mature fruit and stones of ‘NJ355’. Whole fruit are presented in three positions and a transverse cross section to show that the pericarp tends to adhere to the pit when the fruit is mature. The stones illustrate the ovoid 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 large, showy flowers of ‘NJ355’ observed on a tree that was six years of age on Apr. 21, 2004.

FIG. 4 is a color photograph of a tree of ‘NJ355’ in late winter, prior to pruning, that illustrates the spreading growth habit of a tree at the fruit research center in Cream Ridge, N.J. on Feb. 17, 2011.

FIG. 5 is a color photograph taken on Feb. 17, 2011 of immature bark of ‘NJ355’ that illustrates color and the comparatively low density of lenticels that tend to be clustered in small groups on the immature bark.

FIG. 6 is a color photograph taken on Feb. 17, 2011 of mature bark of ‘NJ355’ that illustrates the comparatively rough texture of the mature bark.

The colors and illustration of this type may vary with lighting and other 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.
