ABSTRACT:
BACKGROUND OF THE VARIETY
In the field of plant genetics, we conduct an extensive and continuing plant-breeding program including the organization and asexual reproduction of orchard trees, of which plums, peaches, nectarines, apricots, cherries and interspecifics are exemplary. It is 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 peaches and nectarines known to us, and mentioned herein; ‘Early Sun Grand’ Nectarine (U.S. Plant Pat. No. 1,420), ‘Sun Red’ Nectarine (non-patented), ‘O'Henry’ Peach (U.S. Plant Pat. No. 2,964), ‘Sweet Gem’ Peach (U.S. Plant Pat. No. 7,952), ‘Spring Crest’ Peach (non-patented) and ‘Desert Gold’ Peach (non-patented).
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not applicable.
ORIGIN OF THE VARIETY
The new variety of peach tree (
Prunus persica
) was originated by us in our experimental orchard located near Modesto, Calif. from a first generation cross between two proprietary seedlings with field identification numbers (88ED70) and (7LA283). The maternal parent (88ED70) was originated by us from crosses between the following varieties; ‘Early Sun Grand’ Nectarine (U.S. Plant Pat. No. 1,420). ‘Desert Gold’ Peach (non-patented), ‘O'Henry’ Peach (U.S. Plant Pat. No. 2,964) and ‘Sweet Gem’ Peach (U.S. Plant Pat. No. 7,952). The pollen parent (7LA283) originated from a cross between ‘Sun Red’ Nectarine (non-patented) and ‘Spring Crest’ Peach (non-patented). A large group of these first generation seedlings were planted and grown on their own root system under careful and close observation. One such seedling, which is the present variety, exhibited desirable tree growth and fruit characteristics and was selected in 1992 for asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
Asexual reproduction of the new and distinct variety of peach tree was by budding to ‘Nemaguard’ Rooststock (non-patented), as performed by us, in our experimental orchard located near Modesto, Calif., and shows that all characteristics of the tree and its fruit run true to the original tree and are established and transmitted through succeeding asexual propagations.
SUMMARY OF THE VARIETY
The new variety of peach tree is of large size, vigorous, upright growth and a productive and regular bearer of large, firm, yellow flesh, freestone fruit, having a mild, sub-acid, sweet flavor with very good eating quality. The fruit is further characterized by having an attractive red skin color, being relatively uniform in size throughout the tree and holding firm on the tree 6 to 8 days after maturity (shipping ripe). The tree having a low winter chilling requirement of approximately 350 hours and, in comparison to the low chilling variety parent ‘Desert Gold’ Peach (non-patented), the fruit of the new variety is larger in size, has firmer flesh with greater storage and shipping quality, has a more attractive red skin color and is approximately 18 days later in maturity.
