Abstract: A peach tree which is of large size, open density, vigorous, hardy, upright to spreading-upright, vigorous upright shoots foliated with medium to large size, lanceolate leaves, having acuminate tips, irregular broad crenate margins, mostly globose and occasionally oval and reniform glands which are medium in size, and the stipules are average, light shiny green in color, darkening with age, and early-deciduous with most falling early in the season, blooms abundantly in season with other varieties of peach trees with a hardy, medium size bud which is conical in shape and remaining slightly cupped inwards even at full expansion, pale pink medium flowers, and a regular productive bearer of a heavy, well set crop of medium to large, uniform, somewhat variably formed, very early ripening canning clingstone fruit having light orange red to a darker lacquer red color skin with a light red blush covering 10 percent to 60 percent of the fruit surface varying from a washed pattern to a mottled and dappled spotted pattern, and bright yellow flesh, becoming slightly darker near the stone, and no red coloration is present under the skin surface. The fruit ripens substantially earlier than the earliest commercial variety presently grown, has excellent canned appearance and quality and may now be the earliest volume canning peach variety, allowing earlier opening of the canneries (by approximately two weeks), thus extending the canneries' season.
Claim: We claim:

1. A new and distinct extra-early season variety of a clingstone peach tree having flesh of the yellow variety and substantially as herein shown and described, having firm, finenon-melting flesh texture, the fruit having a sweet, well balanced, rich flavor, being of medium to larger size, light orange-red to a darker lacquer red in color with a light red blush present from 10 percent to 60 percent of the fruit surface, and byhaving a desirable symmetrical shape, where the bloom density is greater, the fruit size is larger and the peach ripens substantially before other existing commercial varieties, typically in late June to early July and has an excellent appearance andquality when canned.

The present new and distinct variety of peach tree was first observed by the inventors in a commercial orchard of "Loadel" cling peach as a single mutated scaffold branch on a tree of "Loadel" peach growing on the "Loadel" topstock itself. Thecommerical orchard where the new variety was discovered is owned and operated by the inventors, and is known as "Filter Farms, Inc.". The inventors observed that the branch was substantially different than the parent "Loadel" and took particular note ofits advanced branch maturity in relation to the parent "Loadel". Thus, the inventors realized that the branch was substantially different from the regular "Loadel" variety in that the new variety was approximately two weeks earlier in maturity. Theinventors then propagated five new trees by budding onto Lovell seedling rootstock; which came true to type from the originally discovered limb sport of the new variety.


A number of plants (five) of the present variety were asexually reproduced from bud wood obtained from the original mutated branch; by placing buds onto Lovell seedling rootstock, the work was performed by the inventors on their commercialorchard in Gridley, Calif. (23 Hurlburt Lane, Gridley, Calif.). These propagated trees first fruited in 1989 and were observed then and in subsequent years to be clones of the originally discovered branch mutation, being identical to the originalmutation scaffold in every distinguishing characteristic.


The present variety of peach tree is, characteristically, of large size, excellent vigor, with an upright to upright-spreading structure. The tree's truck is relatively thick in diameter with rough bark texture. The tree is foliated in anabundant quantity with lanceolate leaves, having acuminate tips. The margins are irregular, and formed with medium sized broad crenations being only slightly undulate. The leaves are generally medium to large in size on vigorous upright shoots. Theleaf stipules are average in size, light shiny green in color, darkening with age. These stipules are early-deciduous with most stipules falling early in the season. The tree blooms at the same time as other commercial cling peach varieties withgrey-brown flowers from 18 to 22 mm. in diameter when fully expanded. The bloom quantity is abundant, being heavier than the parent "Loadel" on the original tree. From 2-3 flowers are present per node. The tree is productive and a regular bearer of aheavy well set crop of medium to large uniform sized peaches of the clingstone variety having bright yellow, firm, fine non-melting textured flesh with no red coloration present in the flesh or near the stone. The new fruit of the variety is slightlylarger in size than the "Loadel". The skin is of average thickenss and moderately pubescent with a uniform covering of light greyish color, medium length hairs. The skin is neutral in acidity and tenacious to the flesh at commercial maturity. Thefruit has a light red blush that can cover from 10 percent to as much as 60 percent of the fruit surface. Most commonly, blush percentages is in the 15 percent to 30 percent range. Blush form varies from a washed pattern to a mottled and dappledspotted pattern. Some blush striping is present in some instances. Ground color is golden yellow and is present over 40 percent to as much as 90 percent of the fruit surface. The fruit ripens evenly.

The tree is a vigorous grower, and upright to upright-spreading in growth characteristics. The tree is productive and a regular bearer. The tree is hardy under typical Sacramento Valley climatic conditions. The truck is relatively thick indiameter with rough surface texture exhibiting moderate scarfskin. The subject tree was pruned to a standard open-vase shaped form. Pollination studies have not been done, however, pollen production is abundant and the new variety is self fertile.

The tree blooms in early to mid March (Mar. 11th in 1993) in the Butte County. The new variety blooms at the same time as other commercial cling peach varieties, including the "Loadel". The tree blooms abundantly, with the number of flowersper node ranging from 2 to 3 (most frequently 2 are present). Flower buds are of medium size. Bud form is conic and relatively free from the stem. The bud surface character is very pubescent. The new variety has a more dense bloom than the "Loadel"variety. The fruit of the new variety matures approximately 2 weeks earlier than the "Loadel" variety, with the first pick on Jun. 25th through Jul. 1st (1992). The "Loadel" ripens from July 10th through July 15th. The fruit of the new variety isslightly larger in size, exhibits more external red blush and darker yellow interior flesh coloration than the "Loadel" variety.

The new variety is an extra early season, non-melting yellow fleshed canning clingstone peach, with a small stone, excellent fruit size and good flavor. The new variety closely resembles the early ripening cling peach variety "Loadel". However,the new variety is distinctly earlier in maturity than "Loadel". Additionally, the new variety enjoys a greater bloom density and somewhat larger fruit than the "Loadel" variety. When canned, the new variety is of high quality and appearance, beingvery similar to the "Loadel" when canned. Currently, the "Loadel" variety is the earliest volume canning peach variety used by commercial canneries. The discovery and eventual commercialization of the new cling peach variety is of substantial value tothe canning peach industry because it will allow for earlier opening of the canneries (by two weeks) and for more efficient utilization of cannery facilities due to the extended season.
