Apple tree named ‘DRF 28 Cltv.’

Abstract

A new and distinct apple variety of gala named ‘DRF 28 Cltv.’ is provided. This variety is distinguished from other apple varieties by its unique combination of finish and color as compared to other Galas in its season.

Description

Latin name of genus and species: Malus x domestica.

Variety denomination: ‘DRF 28 Cltv.’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of apple tree named ‘DRF 28 Cltv.’ that resulted from a sport limb mutation of ‘Fulford Gala’ (U.S. Plant Pat. No. 7,589). The new variety has a similar finish to ‘Fulford Gala’ with a red striped coloration (RHS46A), while the ‘Fulford Gala’ fruit has a blush coloration. The resulting tree was selected when growing in a cultivated area in a commercial orchard in Aspers, Pa.

BRIEF DESCRIPTION OF THE DRAWINGS

This new variety is illustrated by the accompanying photographic drawings of the ‘DRF 28 Cltv.’ plant at approximately four (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 Aug. 21, 2019, of a characteristic twig of ‘DRF 28 Cltv.’ bearing typical leaves of the foliage.

FIG. 2 is a color photograph taken on Aug. 21, 2019, of characteristic mature fruit of ‘DRF 28 Cltv.’ on the tree.

FIG. 3 is a color photograph taken on Aug. 21, 2019. Whole fruit are presented in three positions and both a transverse and longitudinal cross section.

FIG. 4 is a color photograph of a characteristic twig that illustrates the typical open flowers and flower buds of ‘DRF 28 Cltv.’ observed on a tree in a trial block in a commercial setting in Aspers, Pa. on Apr. 29, 2020.

FIG. 5 is a color photograph of a tree of ‘DRF 28 Cltv.’, in mid-summer that illustrates the upright growth habit of a tree in a trial block in a commercial setting in Aspers, Pa. on Aug. 21, 2019.

FIG. 6 is a color photograph of bins of ‘DRF 28 Cltv.’ on left and ‘Simmons Gala’ (U.S. Plant Pat. No. 10,840) on right, both picked on Sep. 23, 2021, to illustrate the color difference between the varieties.

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.

DETAILED BOTANICAL DESCRIPTION

The ‘DRF 28 Cltv.’ variety is distinguished from other apple varieties due to the following unique combination of characteristics:

The fruit has superior coloring over other galas in its season, with an average of 10-15% more overcolor red striping (RHS 46A) than ‘Simmons Gala’ (U.S. Plant Pat. No. 10,840) in Adams County, Pa.

The variety was asexually reproduced in a commercial orchard in Aspers, Pa. Asexual reproduction of this new variety by grafting onto M9(Nic 29) rootstock (non-patented) shows that the foregoing characteristics are so reproduced.

The following detailed description of the ‘DRF 28 Cltv.’ variety is based on observations of an asexually reproduced tree. The observed tree was four (4) years of age and growing on M9/NIC 29 rootstock (non-patented) in a commercial orchard in 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 (R.H.S.) Colour Chart (1966 Ed.)
