7. Early maturity of medium to large, yellow flesh, clingstone fruit.

Description

ORIGIN OF THE VARIETY
The present new and distinct variety of peach tree (Prunus persica) was originated by us in our experimental orchard located near Modesto, Calif., as a seedling from an open pollinated selection of a cross between two selected seedlings with field identification numbers 3HB192 and 104LB628. The heritage of 3HB192 is as follows: ‘May Crest Peach’ (U.S. Plant Pat. No. 4,064) was crossed with ‘Sweet Gem Peach’ (U.S. Plant Pat. No. 7,952), resulting in an unnamed selected seedling. This unnamed selected seedling was crossed with ‘Tasty Gold Nectarine’, producing 3HB192 as progeny.
The cultivar 3HB192 was crossed with 104LB628, resulting in an unnamed seedling. This unnamed seedling was open pollinated, producing the peach tree ‘Sweet Alice’ as progeny.
The heritage of 104LB628 is as follows: ‘May Grand Nectarine’ (U.S. Plant Pat. No. 2,794) was open pollinated, resulting in an unnamed seedling. This unnamed seedling was crossed with ‘May Crest Peach’ (U.S. Plant Pat. No. 4,064), producing 104LB628 as progeny.
‘Sweet Alice’ was chosen from a large group of sibling seedlings growing on their own root which were planted and maintained under close observation by us. We recognized the desirable fruit characteristics of one seedling, which is the present variety, and selected it 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 rootstock (unpatented), 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 fruit are established and transmitted through succeeding asexual propagations.
SUMMARY OF THE VARIETY
The herein new and distinct variety of peach tree is of large size, vigorous, upright growth and a productive and regular bearer of medium to large size, firm, yellow flesh, clingstone fruit with very good flavor and eating quality. The fruit is further characterized by having a high degree of attractive red skin color, holding firm on the tree 7 to 10 days after maturity (shipping ripe), and having good storage and shipping quality. The fruit of the present variety, when compared to the sub-acid Sweet Gem Peach (U.S. Plant Pat. No. 7,952), is similar in flavor and eating quality and is approximately 20 days earlier in maturity.
PHOTOGRAPH OF THE VARIETY
The accompanying color photogaphic 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 fruit divided in its suture plant to show flesh color, pit cavity and the stone remaining in place. The photographic illustration of the fruit was taken shortly after being picked (shipping ripe) and the colors are as nearly true as is reasonably possible in a color representation of this type.
DESCRIPTION OF THE VARIETY
The following is a detailed botanical description of the new variety of peach tree, its flowers, foliage and fruit, as based on observations of specimens grown near Modesto, Calif., with color terminology (except those in common terms) in accordance with Reinhold Color Atlas by A.
