Abstract
A new and distinctive variety of nectarine tree denominated varietally as ‘Burnectone’, and which is characterized as to novelty by a date of maturity for commercial harvesting and shipment of approximately May 25 to June 5, under the ecological conditions prevailing in the San Joaquin Valley of Central California.
Description
The present invention relates to a new, novel and distinct variety of nectarine (Prunus persica) tree, which has been denominated varietally as ‘Burnectone’. The ‘Burnectone’ Nectarine Tree produces an exceptionally high quality, freestone nectarine which is ripe for harvesting and shipment in the early season. Another unique aspect of the ‘Burnectone’ is that it yields a firm nectarine having a very high eating quality.
The present variety of nectarine tree was derived from an ongoing program of fruit and nut tree breeding. The purpose of this program is to improve the commercial quality of deciduous fruit and nut varieties and rootstocks by creating and releasing selections of prunus, malus and regia species. To this end, we make both controlled and hybrid crosses each year in order to produce seedling populations from which improved progenies are evaluated and selected.
The nectarine seedling ‘Burnectone’ was originated by us in 1993, and chosen from among a population of seedlings which resulted from an open pollinated seedling of the ‘May Diamond’ Nectarine Tree (U.S. Plant Pat. No. 5,454). Resulting seed was planted in the spring of 1994. The resulting seed from this cross was planted in the spring of 1995. The new variety was selected from among the seedlings then growing in experimental orchards near the city of Fowler, Calif., County of Fresno, in the central San Joaquin Valley. The ‘Burnectone’ Nectarine Tree was subsequently marked and noted as having exceptional characteristics. This new variety has been repeatedly evaluated during fruiting seasons from 1995-1999. After the 1995 season, the Nectarine Tree ‘Burnectone’ was selected for advanced evaluation and repropagation. Characteristics as described hereinafter are derived from observations of the new variety as grown on ‘Nemared’ rootstocks (unpatented) as well as the original seedling grown on its own root.
Scionwood from the original seedling of the Nectarine Tree, ‘Burnectone’ was collected and grafted in the evaluation plot of the experimental orchards previously described, onto two different and existing ‘Nemared’ rootstocks (unpatented) in February of 1996. Fruit from the resulting propagation has been repeatedly evaluated for the 1997, 1998 and 1999 fruiting seasons. This evaluation has demonstrated that the repropagated trees are true to the characteristics of the original seedling in all observable aspects.
The ‘Burnectone’ Nectarine Tree is characterized as to novelty by producing fruit which ripen in the early season. Further, the fruit of this new variety is considered of very high quality, is firm, and has an attractive exterior coloration. In this regard, the present variety of nectarine tree bears freestone fruit which are ripe for commercial harvesting and shipment approximately May 25 to June 5. These harvesting dates are before the harvest of the commercial freestone varity ‘May Diamond’ Nectarine Tree (U.S. Plant Pat. No. 5,454). Further, the present variety distinguishes itself from the ‘May Diamond’ Nectarine Tree by its brighter exterior coloration, flavor, and lower flesh acidity. The present variety also exhibits a lower frequency of split pits than does the fruit produced by the ‘May Diamond’ Nectarine Tree.
The accompanying drawing are two color photographs, one of a characteristic twig bearing typical leaves; several leaves showing both the dorsal and ventral coloration thereof; and a second photograph displaying several mature fruit showing their external coloration sufficiently matured for harvesting and shipment. Additionally, one fruit of the subject variety is dissected in the equatorial or cheek plane to illustrate the flesh and stone characteristics.
Referring more specifically to the pomological details of this new and distinct variety of nectarine tree, the following has been observed under the ecological conditions prevailing at the orchards located near the town of Fowler, county of Fresno, state of California. All major color code designations are by reference to The R.H.S. Colour Chart (1995 Third Edition) provided by The Royal Horticultural Society of Great Britain.

Apex.—Shape — The stone apex is raised and has an acute tip.
Stone shape.—Considered variable. The stone is normally unequal, although occasionally it may appear nearly equal.
Stone surface.—Surface Texture — Generally, considered medium in roughness and exhibits substantial pitting laterally. Substantial grooving is apparent over the apical shoulders. Surface pitting is prominent, generally, and is more frequently present basally. Ridges — Numerous fine ridgs are present basally and converge towards the base of the stone.
Ventral edge.—Width — Considered average, and having a dimension of approximately 5 to 7 millimeters at mid-suture. The wings are most prominent over the basal area.
Dorsal edge.—Considered full, heavily grooved, and having jagged edges. The dorsal edge is moderately eroded over the apical shoulder.
Stone color.—The color of the dry stone is approximately a light to medium brown, (RHS Orange Red Group 34 C).
Tendency to split.—No splitting noted.
Kernel.—Generally — gelatinous and inmature at the time of ripening.
Use.—The subject nectarine variety ‘Burnectone’ produces fruit which are ripe for harvesting in the early season. Further, the fruit is considered very firm, has a highly attractive exterior color, and is useful for both local and long distance shipping.
Keeping quality.—Fruit has stored well up to 15 days after harvest at temperatures of about 1° C.
