Peach tree named ‘H28-52-96270’

Abstract

A new and distinct peach variety of Prunus persica named ‘H28-52-96270’ is provided. This variety is distinguished from other peach varieties by its unique combination of large showy pink flowers, red coloring of young foliage, flat fruit shape, and high quality nonmelting fruit that ripens in early midseason.

Description

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

Variety denomination: ‘H28-52-96270’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of peach tree named ‘H28-52-96270’. Our new tree resulted from crossing B7-6-151-752080 (unpatented) as the seed parent with NJF4 peach tree (unpatented), as the pollen parent. The resulting tree was selected when growing in a cultivated area as the 52^nd tree in the 28^th row of Block H at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J.

BRIEF SUMMARY OF THE INVENTION

The ‘H28-52-96270’ variety is distinguished from other peach varieties due to the following unique combination of characteristics: large showy pink flowers, red coloring of young foliage, flat fruit shape, and high quality nonmelting fruit that ripens in early midseason. For example, the new variety differs from seed parent ‘B7-6-151-752080’ (unpatented) in that the new variety has flat fruit while the parent has round fruit. The new variety differs from pollen parent ‘NJF4’ (unpatented) in that the new variety has greyed-purple leaves RHS 187a to RHS 187b while the parent has green leaves (upper surface RHS 147a, lower surface 147b). Asexual reproduction of this new variety by budding onto ‘Lovell’ (unpatented) rootstock shows that the foregoing characteristics come true to form, are firmly fixed, and are established and transmitted through succeeding propagations.

The following detailed description concerns the original tree, ‘H28-52-96270’ discovered on Aug. 4, 1999 and progeny first asexually propagated in August 2001 at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J. The original tree and 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

FIG. 1 is a color photograph of a characteristic twig of the new variety in early summer bearing typical leaves and illustrates the ornamental quality of the upper and lower leaf surface of the foliage.

FIG. 2 is a color photograph of a characteristic twig of the new variety in late summer bearing typical leaves and illustrates the difference in color between young and mature foliage.

FIG. 3 is a color photograph of mature fruit of the new variety and stones harvested from the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J. on Aug. 8, 2003. Whole fruit are presented in two positions and a cross section to show that the pericarp adheres to the pit when the fruit is mature. The stones illustrate the high, broad, and very deep dorsal ridge on the stone and the mixture of pits and chains of pits forming grooves on the surface of the stone.

FIG. 4 is a color photograph of a characteristic twig that illustrates the typical flower buds and showy flowers of the new variety observed on a tree at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J.

FIG. 5 is a color photograph of the new variety in early summer that illustrates the spreading growth habit and ornamental qualities of the foliage of a tree at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J.

FIG. 6 is a color photograph of immature bark of the new variety that illustrates color and the moderate density of long lenticels on the immature bark.

FIG. 7 is a color photograph of mature bark of the new variety that illustrates the moderately rough texture of the mature bark.

The color photographs show typical specimens of the leaves, flowers, fruit, and bark of this new peach tree variety and depict the color as nearly true as is reasonably possible to make the same in a color illustration of this character. It should be noted that colors may vary, for example due to lighting conditions at the time the photographs are taken. Therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from the photographs alone.
