Latin name of genus and species of the plant claimed: Prunus persica L.
Variety denomination: ‘NJ362’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of peach tree named ‘NJ362’ that resulted from crossing a peach seedling selection ‘NJ354’ (U.S. Plant Pat. No. 23,669) as the seed parent with ‘H31-122-01232’ (non-patented). The new variety differs from seed parent ‘NJ354’ (U.S. Plant Pat. No. 23,669) in that the new variety produces white fleshed fruit and has a sweeter flavor with rose-like aromatics. The new variety differs from pollen parent ‘H31-122-01232’ in that the new variety ripens about 4 weeks later and more consistently produces fruit. The resulting tree was selected when growing in a cultivated area as the fifty-second (52nd) tree in the eighth (8th) row of Block H at a fruit research farm in Cream Ridge, N.J.
BRIEF SUMMARY OF THE INVENTION
‘NJ362’ differs from the related cultivar ‘White Lady’ (U.S. Plant Pat. No. 5,821), in that trees of ‘NJ362’ crop more consistently and are less susceptible bacterial leaf spot (Xanthomonas campestris pv. pruni) than ‘White Lady’. The ‘NJ362’ variety is also distinguished from other peach varieties due to the following unique combination of characteristics:
Produces medium to large, nearly round, freestone fruit with a low tendency to split when adequately cropped.
Fruits have an attractive greyed-red to greyed-purple blush over a bright yellow-white ground color.
Excellent production of fruit that ripen in late-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, ‘NJ362’. The original tree has been observed growing in a cultivated area at a fruit research farm in Cream Ridge, N.J. Its asexual progeny have been observed growing in a cultivated area in Cream Ridge, N.J and Aspers, Pa. 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 (RHS) Colour Chart (1966 Ed.)
BRIEF DESCRIPTION OF THE DRAWINGS
This new variety is illustrated by the accompanying photographic drawings of the ‘NJ362’ plant in its sixth leaf, 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. 2 is a color photograph taken on Oct. 14, 2022, of characteristic leaves of ‘NJ362’. The leaves are presented in two positions, showing both the upper leaf surface and underside of the leaf.

The colors of 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.
DETAILED BOTANICAL DESCRIPTION
The following detailed description of the ‘NJ362’ variety is based on observations of an asexually reproduced tree. The observed tree was in its sixth leaf and growing on ‘Lovell’ rootstock (non-patented) in a test block at Adams County Nursery, Inc. in Aspers, Pa.
- Scientific name: Prunus persica L.
- Parentage: Seed parent ‘NJ354’; Pollen parent ‘H31-122-01232’.
- Tree:
- Plant hardiness zone.—Growth of plants has only been observed in zone 6b.
- Chilling requirement.—Aspers, Pa., receives about 2300 chilling hours (hours between 32- and 45-degrees Fahrenheit) between November 1 and March 31 each year. This is based on hourly temperature data collected from 2006 to 2020 by the National Oceanic and Atmospheric Administration. Due to the physiology of ‘NJ362’, the chilling requirements of the plant could be lower than the annually acquired 2300 hours. The minimum chilling requirement of the cultivar is unable to be determined because it is limited by the chilling hours accumulated at the growing location in Aspers, Pa.
