BACKGROUND OF THE INVENTION

This invention relates to a peach tree and, more specifically, to a peach tree referred to as a variety of Prunus persica named ‘TRH2B102LW’, which requires approximately 500 chilling units of dormancy, produces a firm, clingstone, white-fleshed, subacid peach with a 60-80% dark red blush over a light-yellow ground color that matures early in the season. The present peach tree was the result of an ongoing Stone Fruit Breeding Program in College Station, Brazos County, Texas. To this end, controlled crosses were made each year to produce seedling populations from which improved progenies are evaluated and selected. ‘TRH2B102LW’ was derived from a population created by crossing the medium chill, white-fleshed, subacid peach ‘White Delight Two’ (not patented) with pollen of the low-chill, yellow-fleshed, peach ‘TexFirst’ (patented). The seed from the ‘White Delight Two’ x ‘TexFirst’ hybrid family were planted in 2011 in an experimental plot in Floresville, TX. ‘TRH2B102LW’ was marked for subsequent observation in 2013 and noted as having exceptional characteristics.

‘TRH2B102LW’ was bud grafted onto virus-free ‘Nemaguard’ (not patented, The Brooks and Olmo Register of Fruit and Nut Varieties, 3rd Ed., American Society of Horticultural Science Press, Alexandria, VA, 1997) peach at the nursery site in Oakdale, CA. The variety was subsequently planted and evaluated as two-year and older trees in Pleasanton (2018-203), Somerville (2016-2023) and Fairfield (2016-2020), Texas. This evaluation clearly demonstrated that the re-propagated trees were true to the characteristics of the original seedling in all observable aspects.

SUMMARY OF THE INVENTION

The ‘TRH2B102LW’ peach is characterized by producing clingstone, white-fleshed, subacid fruit that ripens early in the season and produces a firm, fruit with a 60-80% dark red blush over a light-yellow ground color. In this regard, the present variety of peach tree bears fruit that are ripe for commercial harvesting and shipment in mid-May, when the fruit is grown in the medium chill zone of Texas. ‘TRH2B102LW’ blooms about one week before its female parent ‘White Delight Two’ (not patented; U.S. Ser. No. 14/544,507, abandoned), and about 3 weeks after its pollen parent ‘TexFirst’ (patented, U.S. Plant Pat. No. 26,199). It ripens about 2 weeks before its female parent and about 3 weeks after its pollen parent. ‘TRH2B102LW’ differs from its white-fleshed, subacid, peach female parent as it ripens about 2 weeks before and requires ~100 less chilling hours to fruit. ‘TRH2B102LW’ also differs from ‘White Delight Two’ as it has showy flowers whereas ‘White Delight Two’ has non showy flowers. It differs from its low chill, early ripening, yellow-fleshed peach pollen parent as it is a medium-chill, white-fleshed and subacid peach.

‘TRH2B102LW’ differs from other selections ‘TRH2E122W’ (U.S. Ser. No. 19/295,148), ‘TRH2C108W’ (U.S. Ser. No. 19/336,380) and ‘TRH3C114W’ (U.S. Ser. No. 19/336,169) derived from the same parents as they have acid flesh flavor as compared to the subacid flesh flavor of the ‘TRH2B102LW’. In addition, ‘TRH2E122W’ differs from ‘TRH2B102LW’ as it has more anthocyanin accumulation in the flesh (70-80% vs. 20%), has globose leaf glands rather than reniform leaf glands, has non showy flowers rather than showy flowers, and ripens 3 weeks later than does ‘TRH2B102LW’. All three related varieties bloom about 2 weeks before ‘TRH2B102LW’. Although ‘TRH2C108W’ ripens with ‘TRH2B102LW’, ‘TRH3C114W’ ripens about one week later than ‘TRH2B102LW’ ‘TRH2B102LW’ has showy flower and reniform leaf glands whereas the two commercial, medium-chill, subacid, white-fleshed peaches ‘White Delight One’ (not patented; U.S. Ser. No. 14/544,514, abandoned) and ‘White Delight Two’ have non showy flowers and globose leaf glands. In addition, ‘White Delight One’ ripens about two weeks before and ‘White Delight Two’ ripens about two weeks later than ‘TRH2B102LW’. This new subacid, white-fleshed, clingstone, early ripening peach exhibits potential to be commercialized in regions that have chilling requirements that are moderately low.

 DETAILED BOTANICAL DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of peach tree, the following has been observed under the ecological conditions prevailing at the experimental orchards in the medium chill zone of Texas (Fairfield, Pleasanton, and Somerville). All major color code designations are by reference to The R.H.S. Colour Chart (2001 Edition) provided by The Royal Horticultural Society of Great Britain. Colors are approximate as color depends on horticultural practices such as light level and fertilization rate, among others.

  • Tree:
      • Size.—Generally average to above average as compared to other common peach cultivars ripening in the medium chill zone of Texas.
      • Height.—8-9 feet (2.4-2.7 m) at the end of the 2024 growing season.

      • Productivity.—Produces annually in the medium chill zone of Texas without alternate bearing if temperatures of 28° F. or lower are not experienced during bloom. Trees are self-fertile and must be fruit thinned most years to avoid limb breakage and obtain optimal fruit size. The recommended fruit spacing for early to mid-season ripening fresh market peach cultivars for a full crop is one fruit every 6-8″ of one-year old fruiting wood. Trees often set more fruit than needed for a full crop.
