Apricot tree named ‘NJA152’

Abstract

A new and distinct apricot variety of Prunus armeniaca named ‘NJA152’ is provided. This variety is distinguished from other apricot varieties by its unique combination of a slightly later blooming habit, good production of glossy glabrous fruit with a red blush over a yellow-orange ground color, freestone flesh which has a melting texture and is moderately juicy, and flavor that is sweet-tart and aromatic.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of apricot tree named ‘NJA152’. Our new tree resulted from planting an open pollinated apricot seed from an unknown cultivar. The new variety differs from other apricot cultivars in that the fruit have glabrous skin and the tree tends to bloom later in the spring. The resulting tree was selected when growing in a cultivated area as the 1^st tree in the 82^nd row of Block D at a Research Center in Cream Ridge, N.J.

BRIEF SUMMARY OF THE INVENTION

The ‘NJA152’ variety is distinguished from other apricot varieties due to the following unique combination of characteristics:

• • Trees that tend to bloom slightly later in the spring, resulting in generally good production of fruit that ripens in early mid-season.
  • Glossy, glabrous fruit with a red blush over a yellow-orange ground color.
  • Nearly round to slightly oblong fruit that are slightly compressed.
  • Fruit that are above average in eating quality, with a distinctive aromatic flavor and high soluble solids.

The variety was asexually reproduced at said 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, ‘NJA152’. The original tree and asexual progeny have been observed growing in a cultivated area at said 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 1996 Edition of The Royal Horticultural Society (R.H.S.) Colour Chart.

BRIEF DESCRIPTION OF THE DRAWINGS

This new variety is illustrated by the accompanying photographic drawings, depicting the apricot tree by the best possible color representation using color photography. 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.

FIG. 1 is a color photograph of a tree of ‘NJA152’ in early fall that illustrates the moderately upright growth habit of a 5 year old tree at said Research Center in Cream Ridge, N.J. on Oct. 14, 2011.

FIG. 2 is a color photograph taken on Jul. 2, 2013 of mature bark of ‘NJA152’ that illustrates the moderately rough texture of the mature bark.
