Abstract

A new and distinct variety of plum tree which is distinguished by producing fruit which are mature for harvesting and shipment approximately June 16 to June 20 in the San Joaquin Valley of central California and wherein the fruit is small and round with a crisp and firm flesh which does not bruise easily and having a bright yellow-green skin coloration.

Description

BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of plum tree, which will hereinafter be denominated varietally as the `Yellow #503` plum tree, and, more particularly, to such a plum tree which produces very small bright yellow-green fruit which are mature for commercial harvesting and shipment approximately June 16 to June 20 in the San Joaquin Valley of central California.
The commercial market for tree fruit, as with other fresh fruit and vegetables, is changing to reflect consumer desire for packaged products. As the fruit market develops to reflect consumer desires, the shipping and handling characteristics of fruit that can be included in packaged products become significantly more important. In order for fruit to be suitable to satisfy the market demand for packaged products, it should be of a smaller than usual size, have superior flavor and visual characteristics and be of a firm nature suitable for packaging in plastic bags and other containers.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The plum tree of the present invention was discovered by the inventor as a chance seedling in a nursery located near Reedley in the San Joaquin Valley of central California. The inventor discovered the seedling from seed planted in the nursery in 1989. The first fruit was seen on this seedling in June, 1992. As the fruit matured, it was examined as to size, shape, coloration, ripening date, flavor, texture and as to other criteria which were sought in a plum variety having the desired commercial potential. The initial fruit was very small with a heavy crop having good flavor. The seedling was marked for further testing.
Graft wood was collected from this seedling in the Winter of 1992-1993. Trees were grafted onto Lovell rootstock in the early Spring of 1993 in the testing part of the nursery. The first fruit from these asexually produced trees of the new variety was observed by the inventor in the summer of 1995 and again in 1996. The crop on these trees of the new variety was very heavy with small yellow-green fruit, which had very good flavor. The inventor did not thin the fruit on these trees as it was desired to obtain small fruit for a new market called Lunch Pack. Fruit for this market is packed in eight ounce or one pound packages. The fruit from this new variety of plum tree had the size and flavor desired for this new market.
The harvest time for the asexually produced trees of this new variety was about mid-June, the same time as the parent seedling. These trees produced the same small, round fruit having flesh of a firm texture. The flavor of the fruit was very good. The skin coloration of the fruit was the same bright yellow-green color and the leaves matched the leaves on the parent seedling. The bark and growth pattern characteristics also matched the parent seedling. The inventor has confirmed that the asexually reproduced trees of the new variety are the same in all respects to the parent seedling.
SUMMARY OF THE NEW VARIETY
The `Yellow #503` plum tree is characterized by producing a fruit which has a bright yellow-green skin coloration and is ripe for harvesting and shipment approximately June 16 to June 20 in the San Joaquin Valley of central California. The fruit of the new variety are small in size, fully round in shape and possess an excellent flavor. The pit of this fruit is very small, resulting in a lot of good flavored flesh to eat despite the small size of the fruit. The fruit has been determined to have outstanding storage life, retaining its firm flesh of very good flavor even after thirty (30) days in cold storage. These characteristics of this fruit make it particularly suitable for packaging for sale in the Lunch Pack market.
The asexually produced plum tree of the present invention will set a very heavy crop of fruit that is easy to harvest. The crop does not have to be thinned, thereby saving those costs. The manner in which the tree grows makes it easy to place it on a six-foot trellis, as is done with grapes. This method of growing makes it easy to shape the tree and harvest the crop.
BRIEF DESCRIPTION OF THE DRAWING
The drawing is a color photograph showing mature fruit of the new variety including a first in side elevation, a second in bottom plan view showing the apex area thereof, a third in top plan view showing the base thereof, a fourth in side elevation showing the suture thereof, a fifth sectioned and laid open to show the stone in one section and the stone cavity in the other section, and a sixth showing the stone itself; and representative foliage, all of the new variety.
