Botanical designation: ‘ Prunus persica’. Varietal denomination: ‘Threefoldpeachone’.
BACKGROUND
OF THE NEW VARIETY The present variety of peach tree resulted from a program of fruit tree breeding. The purpose of this program is to improve the commercial quality of deciduous fruit varieties and rootstocks by creating and releasing promising selections of Prunus species. To this end, both controlled and hybrid cross pollinations are made each year to produce seedling populations from which improved progenies are evaluated and selected. The ‘Threefoldpeachone’ peach tree originated in a population of seedlings growing in experimental orchard located near Fresno, California. The breeders pollinated an unnamed, unpatented female parent (peach, Prunus persica ) with an unnamed, unpatented male parent (nectarine, Prunus persica var. nucipersica ). In 2010, seeds obtained from the resulting fruit were planted in pots and grown in a greenhouse as seedlings. The seedlings were later field-planted on their own roots for further growth and observation. The peach tree described and claimed herein was among those seedlings, and was of interest to the breeders because it exhibited desirable characteristics. The seedline, assigned breeder reference ‘H5.003’ and later designated ‘Threefoldpeachone’, was marked for further observation. After the 2013 fruiting season, the new peach tree was selected for advanced evaluation and repropagation. ASEXUAL REPRODUCTION The first asexual reproduction of the ‘Threefoldpeachone’ took place near Fowler, California in 2013, by budding onto ‘Nemaguard’ rootstock (not patented). The claimed plant has been observed to remain true-to-type over successive asexually propagated generations. The distinguishing characteristics of the original tree and its fruit are well-established and appear to be uniformly transmitted through succeeding asexual propagations.
SUMMARY
OF VARIETY ‘Threefoldpeachone’ is a new and distinct peach tree of relatively large size and vigorous growth. The new tree is a regular and productive bearer of relatively large, firm, yellow-fleshed, non-melting clingstone fruit having desirable flavor, flesh texture and eating qualities. The claimed peach tree has a medium-low chilling requirement of approximately 250 hours, and produces relatively uniformly-sized fruit throughout the canopy. ‘Threefoldpeachone’ peaches are typically ripe for commercial harvesting and shipment from about June 2 to about June 10 under the ecological conditions prevailing in the San Joaquin Valley of central California. The fruit exhibits good handling and shipping qualities. The claimed plant is distinguished from its unnamed, unpatented female parent by its fruit, which exhibits non-melting flesh as compared to the melting flesh of the female parent. Additionally, fruit from the claimed plant achieves significantly more external red blush coloration as compared to the female parent. The distinguishing difference between the claimed peach tree and its male parent is that the male parent is a nectarine tree. In comparison to ‘June Time’ (U.S. Plant Pat. No. 23,530), the closest known yellow-fleshed peach variety, ‘Threefoldpeachone’ ripens 7 to 9 days earlier and expresses 2% to 3% higher soluble solids as compared to fruit from the ‘June Time’ peach tree.

DETAILED DESCRIPTION
Referring more specifically to the details of this new and distinct variety of peach tree, the following has been observed during the sixth fruiting season on multiple replicated trees and under the ecological conditions prevailing at orchards located near Fresno, California. The described trees were grown on ‘Nemaguard’ rootstock (not patented). It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and will vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant or any group of plants of the new variety may vary from the stated average. All colors are described with reference to The R.H.S. Colour Chart, 4 th ed. (Royal Horticultural Society 2001). Tree: Size .—The tree of the present variety was pruned to a height of about 290.0 cm to about 320.0 cm at commercial maturity. Width .—About 305.0 cm. Vigor .—Very vigorous as compared to other common commercial peach cultivars ripening in the early season of maturity. The present peach tree variety grew from about 195.0 cm to about 200.0 cm in height during the first growing season. The new variety was pruned to a height of about 170.0 cm after the first dormant season, and primary scaffolds were then selected for the desired tree structure. Productivity .—Productive. Fruit set varies, from more than the desired crop load to levels higher than desired amounts when the new variety is grown in a suitable horticultural zone and under appropriate commercial nursery conditions. The fruit set is spaced by thinning to develop the remaining fruit into the desired market- sized fruit. The quantity of fruit set varies with the prevailing climatic conditions and the cultural practices employed. Fruit bearing .—Regular. Fruit set has been adequate during the previous years of observation, and thinning was necessary during the past 10 years on both the original seedling and on subsequent asexually reproduced trees. Tree form .—Upright and pruned into a vase shape. Density .—Moderate. Hardiness .—The present tree was grown and evaluated in USDA Hardiness Zone 9. The calculated winter chilling requirement of the new tree is approximately 250 hours at a temperature below 7.0 degrees C. Hardy under typical central San Joaquin Valley climatic conditions. Trunk: Diameter .—About 26.0 cm in diameter when measured at about 15.5 cm above the soil level. This measurement was taken from replicated trees at the beginning of the tenth growing season. Bark texture .—Moderately rough with an abundance of lenticels. Lenticels .—Numerous flat, oval lenticels are present. The lenticels range in size from about 5.0 mm to about 8.0 mm in width, and between about 2.0 mm and about 3.0 mm in height. Density is approximately 6 per square cm. Lenticel color .—Orange brown (RHS Greyed-Orange Group 167B). Bark coloration .—Variable, generally greyed tan (RHS Grey-Brown Group N199D).
