USPP33546P2 - Apple tree named NJ150 - Google Patents

Abstract

A new and distinct apple variety of Malus x domestica Borkh. named ‘NJ150’ is provided. This variety is distinguished from other apple varieties by its unique combination of excellent production large, high quality aromatic fruit with an attractive red (RHS 53A) blush over a yellow (RHS 11C) ground color on trees that are highly tolerant to cedar apple rust (Gymnosporangium juniperiviriginianae) and apple scab (Venturia inaequalis) and have low susceptibility to fire blight.

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: Malus x domestica Borkh.

Variety denomination: ‘NJ150’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of apple tree named ‘NJ150’ that resulted from crossing ‘Co-op 38’ (also known as ‘Goldrush’, U.S. Plant Pat. No. 9,392) as the seed parent with ‘Co-op 30’ (also known as ‘Enterprise’, U.S. Plant Pat. No. 9,193) as the pollen parent. The resulting tree was selected when growing in a cultivated area as the 206^th tree in the 18^th row of Block DW at a fruit research farm in Cream Ridge, N.J.

BRIEF SUMMARY OF THE INVENTION

The ‘NJ150’ variety is distinguished from ‘Co-op 38’ (also known as ‘Goldrush’, U.S. Plant Pat. No. 9,392) in that the new variety has more tolerance to cedar apple rust (Gymnosporangium juniperiviriginianae), ripens about one month earlier, and produces fruit that have a better finish and color. The new variety differs from ‘Co-op 30’ (also known as ‘Enterprise’, U.S. Plant Pat. No. 9,193) in that the ripens about one week earlier, and produces larger fruit that have a brighter overcolor and better fruit texture and flavor.

Trees are highly tolerant to cedar apple rust (Gymnosporangium juniperiviriginianae) and apple scab (Venturia inaequalis) and have low susceptibility to fire blight.

Excellent production of large fruit that ripen in mid-late season.

Fruit have superior eating quality due to their aromatic, sweet, and mild acidic 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 ‘EMLA 7’ rootstock (non-patented) shows that the foregoing characteristics are so reproduced.

The following detailed description concerns the original tree, ‘NJ150’. 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 ‘NJ150’ plant at approximately 4 years old, depicting the apple 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 Oct. 16, 2019, of a characteristic twig of ‘NJ150’ bearing typical leaves of the foliage.

FIG. 2 is a color photograph taken on Oct. 19, 2020, of characteristic mature fruit of ‘NJ150’. Whole fruits are presented in three positions and both a transverse and longitudinal cross section to illustrate their globose shape, flaring cavity and persistent sepals with erect tips.

FIG. 3 is a color photograph of a characteristic twig that illustrates the typical open flowers and flower buds of ‘NJ150’ observed on a tree at a fruit research farm in in Adams County, Pa. on Apr. 22, 2019.

FIG. 4 is a color photograph of a tree of ‘NJ150’, in mid-summer that illustrates the upright growth habit of a tree at the fruit research farm in in Adams County, Pa. on Aug. 28, 2019.

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.
