USPP21378P2 - Peach tree named ‘KV00398’ - Google Patents

Abstract

A new and distinct variety of peach which is characterized by producing large, yellow, melting-flesh fruit with an excellent sweet, only mildly acidic dessert quality flavor. Fruit are melting flesh freestone with an 80% red over-color (blush) over a golden yellow undercolor and average 71 to 75 mm in diameter, ripening in early mid season.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of peach tree [Prunus persica (L.) Batsch] which is named ‘KV00398’.

The new variety was originated at the Appalachian Fruit Research Station, Agricultural Research Service, U.S. Department of Agriculture in Kearneysville, W. Va. and was identified as KV00398. The present new variety, selected as KV00398 is a seedling selection of ‘BY96P3480’ which is a seedling of ‘Blazeprince’בBY90P2932’. ‘Blazeprince’ is a seedling resulting from 2 generations of open pollination of ‘O'Henry’ peach. BY90P2932 is a seedling of open pollination of BY87P1865 which in turn was a seedling of open pollination of BY84P1722 which was a seedling of (Flavortop×Fla. WL-1).

It was selected in 2003 from a group of 41 seedlings of the before said parent. It was vegetatively propagated by bud-grafting on to standard rootstock. The tree was propagated by a commercial nursery in Pennsylvania. Propagated trees were grown at the USDA-ARS-Appalachian Fruit Research Station and evaluated for trueness to type at that location in proximity to the original tree that was the source of propagative material. Testing for 5 years has shown that said variety maintains high fruit quality, large fruit size, a sweet and mild acidic flavor, and productivity. No aberrant types have appeared.

KV00398 is diploid, self-fertile and is cross compatible as a male or female parent with other peach varieties. No pollination incompatibilities have been noted.

This new variety is distinct from its parent in its combination of large size fruit, high fruit quality, sweet mildly acidic fruit, with an early mid-season time of ripening.

The fruit of this variety are melting flesh, dessert type. This variety is distinct from other peach cultivars in its combination of four distinct characteristics: (1) large size fruit, (2) yellow, melting-flesh fruit, (3) a distinct sweet, mildly acidic flavor, and (4) an outer appearance of 80% red blush over a golden yellow ground color. Flesh is yellow, flavorful sweet and only mildly acidic. They remain firm until full-ripe. Fruit have yellow ground color with red blush that covers approximately 80% of the fruit surface at maturity. Fruit size at harvest ranges from averages 70-80 mm in diameter with an average weight of 220 g. Fruit are sweet and flavorful with a mild acidity. Brix of firm-ripe fruit averages approximately 10° but can range from 9-12 depending on date of harvest and environment. Fruit maintain firmness on the tree and in storage at levels comparable to commercial peach cultivars.

SUMMARY OF THE INVENTION

A peach tree producing large yellow, melting-flesh fruit with a distinct sweet, mildly acidic flavor, of large size with approximately 80% red blush over a golden yellow ground color.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a photograph of the fruit of the Fruit of ‘KV00398’ peach in full color showing the ripe fruit viewed in profile and sectioned in half from end to end, with one-half of the fruit shown with the stone in place in the flesh.

FIG. 2 is a full color photograph of a representative stem of flowers of the KV00398 peach at “balloon” stage.

The figures show photographs in color as accurate as reasonably possible to attain in color photographic reproductions of this type.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of the botanical and pomological characteristics of the subject peach. Color data are presented in Royal Horticultural Society (R.H.S.) Colour Chart designations. Where dimensions, sizes, color, and other characteristics are given, it is to be understood that such characteristics are approximations of averages set forth as accurately as practicable.

Age and growing conditions of plant observed and reported herein are from specimens grown at Kearneysville, W. Va. Data was taken from a 8 year old tree growing on its own roots growing at the USDA-ARS Appalachian Fruit Research Station—GPS coordinates 39° 21′ 03″ N, 77° 52′ 53″ W. The tree was planted in a field that received 40 lbs of nitrogen per acre. Field evaluations under a normal program of disease and pest control (see 2010 Spray Bulletin for Commercial Tree Fruit Growers, D.G. Pfeiffer et al. Virginia Cooperative Extension Publication 456-419 [Retrieved from the Internet: www.ext.vt.edu]) show no marked susceptibility to pathogens or insects when compared with peach varieties adapted to the eastern U.S. such as ‘Bounty’, ‘Sweet-N-Up’, and ‘Sentry’.
