Abstract

A new and distinct peach variety of Prunus persica named ‘NJ360’ is provided. This variety is distinguished from other peach varieties by its unique combination of showy flowers, medium to large, round, semi-freestone fruit, with a red to greyed-purple blush over a bright yellow-white ground, ripening in mid-season, and possessing aromatic, sweet, sub-acid flavor.

Description

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

This invention was made with government support under, contract or grant Multistate Research Project NE-9, entitled Conservation and Utilization of Plant Genetic Resources, awarded or sponsored by the National Institute of Food and Agriculture. The government has certain rights in the invention.

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

Variety denomination: ‘NJ360’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of peach tree named ‘NJ360’ that resulted from crossing a peach seedling selection ‘H24-128-01224’ (non-patented) as the seed parent with ‘NJ354’ (U.S. Plant Pat. No. 23,669). The new variety differs from seed parent ‘H24-128-01224’ in that the new variety produces white fleshed fruit that ripen 3 days earlier and have different, more preferable values of flavor and aromatics. The new variety differs from pollen parent ‘NJ354’ in that the new variety ripens about 2 weeks later and more consistently produces fruit with different, more preferable values of sweetness and flavor. The resulting tree was selected when growing in a cultivated area as the 135^thtree in the 14^throw of Block H at a fruit research farm in Cream Ridge, N.J.

BRIEF SUMMARY OF THE INVENTION

‘NJ360’ differs from the related cultivar ‘White Lady’ (U.S. Plant Pat. No. 5,821), in that trees of ‘NJ360’ crop more consistently are less susceptible bacterial leaf spot (Xanthomonas campestris pv. pruni) than ‘White Lady’. The ‘NJ360’ variety is also distinguished from other peach varieties due to the following unique combination of characteristics:

Produces medium to large, nearly round, semi-freestone fruit with a low tendency to split when adequately cropped.

Fruits have an attractive red to greyed-purple blush over a bright yellow-white ground color.

Excellent production of fruit that ripen in mid-season on trees with low susceptibility to bacterial leaf spot.

Fruit have superior eating quality due to their aromatic, sweet, and sub-acid flavor.

The variety was asexually reproduced at a fruit research farm in Cream Ridge, N.J. Asexual reproduction of this new variety by budding onto >Lovell=peach seedling rootstock (non-patented) shows that the foregoing characteristics are so reproduced.

The following detailed description concerns the original tree, ‘NJ360’. The original tree and asexual progeny have been observed growing in a cultivated area at a fruit research farm 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 Ed.)

BRIEF DESCRIPTION OF THE DRAWINGS

This new variety is illustrated by the accompanying photographic drawings of the ‘NJ360’ plant at approximately seven (7) years old, 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. 12, 2019 of a characteristic twig of ‘NJ360’ in mid-summer bearing typical leaves of the foliage.

FIG. 2 is a color photograph taken on Jul. 29, 2019 of characteristic mature fruit and stones of ‘NJ360’. Whole fruit are presented in two positions and both a transverse and longitudinal cross section to illustrate that the pericarp partially adheres to the pit when the fruit is mature. The stones exemplify the obovate shape and pits and grooves on the surface of the stone.

FIG. 4 is a color photograph of a dormant tree of ‘NJ360’, prior to pruning, in early spring that illustrates the spreading growth habit of a tree at the fruit research farm in Cream Ridge, N.J. on Mar. 26, 2019.

FIG. 5 is a color photograph taken on Sep. 26, 2019 of immature bark of ‘NJ360’ that illustrates color and the moderate density of conspicuous elliptic lenticels on the immature bark.

FIG. 6 is a color photograph taken on Sep. 26, 2019 of mature bark of ‘NJ360’ that illustrates the greyed-green color, slightly rough texture, with sparse, broad, very shallow furrows on 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.
