ABSTRACT:
Variety denomination: Variety of
Prunus persica
, denominated as ‘TexPrince’.
BACKGROUND OF THE INVENTION
The present invention relates to a new, novel and distinct variety of peach tree, which is denominated varietally as ‘TexPrince’. The ‘TexPrince’ peach tree produces a high quality, firm freestone peach that matures early mid-season and requires approximately 500 to 550 chilling units of dormancy.
BRIEF SUMMARY OF THE INVENTION
The ‘TexPrince’ peach is characterized as to novelty and is otherwise noteworthy by producing fruit which ripens in the early midseason that is high quality, firm and has attractive coloration. In this regard, the present peach tree variety bears fruit that are ripe for commercial harvesting and shipment in early to middle June, when the fruit is grown in central Texas. This is comparable to or shortly after the peach tree varieties ‘TexRoyal’ (not patented) (Byrne and Bacon, 1991,
HortScience
26:1338-1340) and ‘Juneprince’ (not patented) (Okie and Reilly, 1987,
HortScience
22:325-326). Additionally, ‘TexPrince’ exhibits the potential to be commercialized in regions that have relatively low chilling requirements (i.e., 500 to 600 chilling units) or in regions having higher chilling requirements provided spring frosts do not occur.
ORIGIN OF THE VARIETY
The present peach tree was the result of an on going Stone Fruit Breeding Program of Texas A&M University, College Station, Tex. To this end, both controlled and hybrid crosses are made each year in order to produce seedling populations from which improved progenies are evaluated and selected.
The seedling ‘TexPrince’ originated at the Stone Fruit Breeding Program of the Department of Horticultural Sciences, Texas A&M University, located in College Station, Tex. In 1989, a controlled cross was made on selection P60-12 at the USDA, ARS Horticulture Fruit Crops Research Laboratory. The P60-12 selection is a selection from a cross between ‘Firebrite’ (ASHS, 1997, The Brooks and Olmo Register of Fruit and Nut Varieties) and ‘Sunfre’ (Ramming and Andrews, 1982,
HortScience
17:412), and was pollinated with pollen from ‘Flordaking’, a non-patented variety released by the University of Florida (Andrews et al., 1979,
HortScience
14:81-82).
Resulting seedlings from this cross were planted in a high-density fruiting nursery at College Station in 1990. In 1992, ‘TexPrince’ was marked for subsequent observation and noted as having exceptional characteristics, including mid-season maturity, large fruit size, good productivity, yellow ground color, round shape, high red overcolor, and excellent firmness. It was propagated asexually by budding and has been evaluated in Texas and California.
ASEXUAL REPRODUCTION
The new variety ‘TexPrince’ was bud grafted onto virus free ‘Nemaguard’ (not patented) (ASHS, 1997, The Brooks and Olmo Register of Fruit and Nut Varieties) peach rootstock in May, 1992. The budded trees of ‘TexPrince’ were planted at the experimental orchards at Texas A&M University near the city of College Station, Tex., County of Brazos and near the city of Yoakum, Tex., County of Dewitt. Additionally, the trees were planted at the experimental orchards near the city of Fowler, Calif., County of Fresno, in the central portion of the San Joaquin Valley of California. Fruit from the resulting propagation has been evaluated for the 1995 to 2001 fruit seasons in College Station and in Yoakum, and for the 1998 to 2001 fruit seasons in Fowler. This evaluation clearly demonstrated that the re-propagated trees are true to the characteristics of the original seedling in all observable aspects.
