Abstract

A new and distinct variety of peach tree (Prunus persica). The following features of the tree and its fruit are characterized with the tree budded on ‘Nemaguard’ Rootstock (non-patented), grown on Handford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consist of the following combination of desirable features:

• • 1. Tree with vigorous, upright growth.
  • 2. Regular and productive bearer of large size fruit.
  • 3. Fruit with firm, non-melting, yellow flesh suitable for mechanical pitters.
  • 4. Fruit with good flavor and eating quality.
  • 5. Fruit with good storage and shipping quality.

Description

Botanical designation: Prunus persica.

Variety denomination: ‘Clayey’.

BACKGROUND OF THE VARIETY

1. 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.

2. Prior varieties

Among the existing varieties of peach trees, which are known to us, and mentioned herein, ‘Diamente’ Peach (non-patented), ‘Klamath’ Peach (U.S. Plant Pat. No. 15,557), our proprietary non-patented peach seedling selections ‘14HA602’, ‘286LC126’, ‘13EB307’ and the non-patented cling peach seedling ‘A297’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

Not applicable.

ORIGIN OF THE VARIETY

The new and distinct variety of peach tree (Prunus persica) was developed by us in our experimental orchard located near Modesto, Calif. as a first generation cross between our proprietary non-patented peach seedling selections ‘14HA602’ and ‘288LC126’. The seed parent (14HA602) originated as an open pollinated seedling selection from ‘Diamente’ Peach (non-patented). The pollen parent (288LC126) originated from a first generation cross between the non-patented cling peach seedling ‘A297’ and our proprietary non-patented peach seedling ‘13EB307’. A large number of these first generation seedlings were planted and grown on their own root system. Under close and careful observation we recognized the desirable tree and fruit characteristics of the present seedling and selected it in 1993 for additional asexual propagation and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

In 1993 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 present new variety of peach tree (Prunus persica) is of large size, vigorous, upright growth and a regular and productive bearer of large size, non-melting, yellow flesh, clingstone fruit with good flavor and eating quality. The fruit is further characterized by having an attractive orange skin color and maturing relatively uniform throughout the tree and maintaining excellent shape, texture, color and appearance after being canned. In comparison to its proprietary non-patented seed parent (14HA602) the fruit of the new variety is larger in size and is approximately 4 days earlier in maturity. In comparison to its proprietary non-patented pollen parent (288LC126) the fruit of the new variety has good flavor and has yellow flesh compared to orange. In comparison to the commercial variety ‘Klamath’ Peach (U.S. Plant Pat. No. 15,557) the fruit of the new variety is approximately 15 days earlier in maturity.

DESCRIPTION OF THE PHOTOGRAPH

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 19 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.

Under close observation during planting, growing, and harvesting of fruit, under normal cultural and growing conditions near Modesto, Calif., no particular plant/fruit disease resistance or susceptibility has been observed. Any variety or selection observed during indexing of plant characteristics with abnormal fungus, bacterial, virus or insect susceptibility is destroyed and eliminated from our breeding program. No atypical resistances/susceptibilities. have been noted under normal cultural practices. The present new variety of peach tree, its flowers, foliage and fruit herein described may vary in slight detail due to climate, soil conditions and cultural practices under which the variety may be grown.
