Abstract

Description and specifications of a new and distinct nectarine tree variety which originated from seed produced by a hand pollinated cross of Arkansas Nectarine Selection 178 (non-patented) and Arkansas Nectarine Selection 232 (non-patented) is provided. This new nectarine variety can be distinguished by its very early fruit maturity, very firm non-melting flesh texture, high yield, excellent tree vigor, and attractive fruits with good flavor.

Description

SUMMARY OF THE INVENTION
The new and distinct variety of nectarine tree originated from a hand pollinated cross of Arkansas Nectarine Selection 178 (non-patented)×Arkansas Nectarine Selection 232 (non-patented) made in 1984 at the Arkansas Agricultural Experiment Station Fruit Substation at Clarksville, Ark. The parent plants used in this hybridation have not been named and released and are unavailable in commerce.
Plants and fruit of this new variety differ phenotypically from its parents. The new variety produces larger fruits, with better flavor, and more vigorous and productive trees than the parent Arkansas Nectarine Selection 178, and is earlier ripening, more vigorous, more productive, and produces larger fruits than the parent Arkansas Nectarine Selection 232. Both the parents and the instant variety are the genus and species Prunus persica.
The seeds resulting from this controlled hybridization were germinated in a greenhouse in the spring of 1985 and planted in a field on the Arkansas Agricultural Experiment Station in Clarksville, Ark. The seedlings fruited during the summer of 1989 and one, designated Arkansas 417, was selected for its very early ripening, attractive fruits, firm fruit texture, and good fruit quality. During 1989, the original plant selection was propagated asexually, at the above noted location, by budding onto standard peach rootstock variety ‘Lovell’ (non-patented) and a test plot of two plants was established. Subsequently, larger test plantings have been established with asexually multiplied plants (propagated at the same location by budding) at two additional locations in Arkansas (Clarksville, and Hope, Ark.).
The new variety has been asexually multiplied by budding several times at this same location since 1989 by budding onto ‘Lovell’ peach rootstock and no incompatibility with this peach rootstock has occurred following budding. During all asexual multiplication, the characteristics of the original plant have been maintained and no aberrant phenotypes have appeared.
Plants of the new variety are vigorous and productive. Trees are standard in size in comparison to other nectarine or peach trees (Prunus persica), well branched and symmetrical with an upright growth habit. Plants and fruit are moderately tolerant to peach bacterial spot, incited by Xanthomonas campestris pv. pruni (Smith) Dye. The new variety blooms in the spring an average of 3 days earlier than the ‘Redgold’ (U.S. Plant Pat. No. 1,329) and ‘Summer Beaut’ (U.S. Plant Pat. No. 4,093) varieties. No winter injury has been observed on wood or buds of the new variety in Arkansas test where minimum temperatures have reached −23° C. Chilling requirement to break dormancy is estimated to be 750 hours below 7° C.
Fruit of the new variety ripens very early, averaging 28 days earlier than the ‘Redgold’ variety, 18 days earlier than the ‘Summer Beaut’ variety, and 9 days earlier than the reference peach variety ‘Redhaven’ (non-patented). Average ripening date is June 24 in central Arkansas. Fruits are very firm at maturity and fruit quality is retained well on the tree after maturity for 5 to 7 days. Fruit yields are very good, and the new variety outyielded the ‘Redgold’ and ‘Summer Beaut’ varieties in all replicated test plantings in Arkansas. Yields are consistent from year to year.
The fruit of the new variety is round in shape, with light, bright red skin color over yellow ground color. Fruit size is medium, averaging 125.1 g, and is slightly smaller than the ‘Redgold’ and ‘Summer Beaut’ varieties. Careful management of crop load is required to enhance fruit size. The fruit is non-melting in texture and very firm at maturity, rating much more firm than the ‘Redgold’ and ‘Summer Beaut’ varieties. Storage ability of fresh fruit of the new variety is superior to both the ‘Redgold’ and ‘Summer Beaut’ varieties in that it is has firmer flesh at maturity resulting in longer storage capability. Fruit cracking has not been observed on the instant variety. The flesh of the fruit is a uniform yellow color with no red pigment present. The fresh fruit rates good in flavor and is especially good for a very early ripening nectarine. The flavor is sweet and mildly subacid, wtih a mild nectarine aroma. The soluble solids concentration averages 12.2% and exceeds 15.0% in some years.
The distinctive features of the new variety are its very early fruit ripening, very firm non-melting flesh texture, high yields, excellent tree vigor, and attractive fruits with good flavor.
The new variety has been named the ‘ARRINGTON’ cultivar.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show typical specimens of the fruit (FIGS. 1 and 2) and leaf (FIG. 3) of the new variety in color as nearly as it is reasonably possible to make in a color illustration of this character.
DETAILED DESCRIPTION OF THE NEW VARIETY
The following is a detailed description of the botanical and pomological characteristics of the subject nectarine. Color data are presented in Royal Horticultural Society Colour Chart designations and are supplemented with readings from a Minolta Chroma Meter CR-200, version 3.0, which measures absolute chromaticity in tristimulus values L, a, and b. Calibration was performed using a standard white plate supplied by the manufacturer.
Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations of averages set forth as accurately as practical.
The descriptions reported herein are from specimens grown at Clarksville, Ark. and are from trees grown in trickle (drip) irrigated orchards growing on a Linker fine sandy loam soil. The data were collected from eight-year old trees of the instant variety except yield data that were taken on five-year-old trees in a replicated test planting.
Tree:
Size.—Mature trees (5 years of age and older) average 3.4 m to 3.7 m in height and 4.7 to 5.6 m in spread or width and have an upright growth habit, as grown on ‘Lovell’ rootstock using an open-center training system commonly used on nectarines. Tree size is comparable to that of the ‘Red Gold’ and ‘Summer Beaut’ varieties.
Growth.—Very vigorous, symmetrical form, good canopy development. Vigor comparable to that of the ‘Red Gold’ and ‘Summer Beaut’ varieties.
Productivity.—Very good and consistent from year to year. Yield measured 43.5 kg/tree on five-year old trees and exceed the yield of ‘Summer Beaut’ of 30.8 kg/tree and ‘Red Gold’ of 16.7 kg/tree in a test planting of identical age and growing conditions.
Cold hardiness.—Wood and dormant buds hardy to −23° C.
Disease resistance.—Leaves and fruit moderately resistant to bacterial spot under growing conditions where bacterial spot infection is often very severe on susceptible genotypes. No bactericides were used in the development or evaluation of the instant cultivar. Evidence of bacterial spot infection less than that of ‘Red Gold’ and comparable in most years to that of ‘Summer Beaut’ in all years of evaluation. A commercial fungicide program was utilized in orchards used in the development and evaluation of the instant variety, thus no resistance to brown rot or scab, the other common diseases at Clarksville, Ark., was determined.
Insect resistance.—Insecticides were applied to orchards used in the development of the instant variety to control the common insects at the location including oriental fruit moth, plum curculio, stinkbug, tarnished plant bug, lesser peach tree borer and greater peach tree borer. Therefore no insect resistance was determined in the testing of the instant variety.
