Description

Botanical designation: Prunus persica.

Variety denomination: ‘Sauzee Lady’.

BACKGROUND OF THE VARIETY Field of the Invention

In the field of plant genetics, we conduct an extensive and continuing plant-breeding program including the organization and asexual reproduction of orchard trees, and of which plums, peaches, nectarines, apricots, cherries, almonds and interspecifics are exemplary. It was against this background of our activities that the present variety of peach tree was originated and asexually reproduced by us in our experimental orchard located near Modesto, Stanislaus County, Calif.

PRIOR VARIETIES

Among the existing varieties of peach and nectarine trees, which are known to us, and mentioned herein, ‘Sugar Lady’ Peach (U.S. Plant Pat. No. 7,532), ‘Carolyn’ Peach (non-patented), ‘Fayette’ Peach (non-patented), ‘May Grand’ Nectarine (U.S. Plant Pat. No. 2,794), ‘Royal Gold’ Peach (U.S. Plant Pat. No. 2,663), ‘Red Grand’ Nectarine (U.S. Plant Pat. No. 1,060) ‘Redwing’ Peach (U.S. Plant Pat. No. 621) ‘Sauzee Queen’ Peach (U.S. Plant Pat. No. 16,179) and the proprietary selections ‘52LA314’ and ‘333LH428’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

Not applicable.

ORIGIN OF THE VARIETY

The new and distinct variety of peach tree (Prunus persica) was originated by us in our experimental orchard located near Modesto, Stanislaus County, Calif. as a first generation cross between two proprietary seedlings with the field identification numbers ‘52LA314’ and ‘333LH428’. The seed parent (52LA314) originated from crosses between the following varieties; ‘Fayette’ Peach (non-patented), ‘Royal Gold’ Peach (U.S. Plant Pat. No. 2,663), ‘Redwing’ Peach (U.S. Plant Pat. No. 621), ‘Sugar Lady’ Peach (U.S. Plant Pat. No. 7,532) and ‘Red Grand’ Nectarine (U.S. Plant Pat. No. 1,060). The pollen parent (333LH428) originated from crosses between the following varieties; ‘Carolyn’ Peach (non-patented), ‘Fayette’ Peach (non-patented), ‘May Grand’ Nectarine (U.S. Plant Pat. No. 2,794) and a peento peach of unknown parentage. We planted and grew a large number of seed from this first generation cross on their own root system, and under careful and close observation, recognized the desirable tree and peento fruit characteristics of the present variety and selected it for asexual propagation and commercialization in 2001.

ASEXUAL REPRODUCTION OF THE VARIETY

Asexual reproduction of the new and distinct variety of peach tree was by budding to ‘Nemaguard’ Rootstock (non-patented), as performed by us in our experimental orchard located near Modesto, Calif., and shows that reproductions run true to the original tree and all characteristics of the tree and its fruit are established and transmitted through succeeding asexual propagations.

SUMMARY OF THE NEW VARIETY

The new variety of peach tree (Prunus persica) is of large size, vigorous upright growth, a regular and productive bearer of medium to large, white flesh clingstone fruit. The fruit is further characterized by having an attractive light red blush, mild, sweet sub-acid flavor, very good eating quality and is peento in shape. In comparison to its proprietary seed parent (52LA314) the new variety is a peach instead of a nectarine tree, the fruit is peento in shape compared to globose and is approximately 1 month earlier in maturity. In comparison to its proprietary pollen parent (333LH428) the fruit has firmer texture, more uniform attractive light red skin color, is larger in size with the same peento shape and requires approximately 300 more winter chilling hours at or below 45° F. In comparison to the commercial variety ‘Sauzee Queen’ Peach (U.S. Plant Pat. No. 16,179) the fruit of the new variety matures approximately 73 days later.

PHOTOGRAPH OF THE VARIETY

The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new peach variety. The illustration shows the upper and lower surface of the leaves, an exterior and sectional view of a single fruit divided in its suture plane to show flesh color, pit cavity and the stone remaining in place. The photographic illustration was taken shortly after being picked (shipping ripe) from a 7 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.
