Abstract

A new variety of plum tree which is remotely similar to the unpatented ‘Early Beaut’ plum tree but is distinguished from it by producing uniformly purple skin coloration fruit which are mature for harvesting and shipment one week earlier than the ‘Early Beaut’ plum tree and exhibits superior holding capacity than the ‘Early Beaut’ plum tree and having more yellow flesh throughout.

Description

BACKGROUND OF THE NEW VARIETY
This present invention relates to a new and distinct variety of plum tree which will hereinafter be denominated varietally as the ‘Early Danae’ plum tree and more particular to a plum tree which produces fruit which are mature for commercial harvesting and shipment about May 20-25 in the San Joaquin Valley of Central California and which is further distinguished from one of its parent ‘Showtime’ plum tree (U.S. Plant Pat. No. 8,037) in that it produces fruits that have a dark purple skin coloration which can be retained on the tree and remains firm to a high level of maturity. In addition, the flesh of the fruit of this invention is a yellow gold color throughout with the shape of the fruit being somewhat flatter at the stem end.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The present variety was discovered as an open, pollinated hybrid of the ‘Showtime’ plum tree (U.S. Plant Pat. No. 8,037) in a sixteen acre plum orchard located approximately ½ mile south of Manning Avenue in Parlier, Calif. The grafting of the scion wood of the new invention took place at that location. The grower has observed this invention since 1999 and confirmed that distinctive characteristics of the parent tree are precisely reproduced in the progeny.
SUMMARY OF THE NEW VARIETY
The ‘Early Danae’ plum tree is characterized as to novelty by producing a medium size fruit generally of dark purple skin coloration, ripe for commercial harvest and shipment approximately May 20-25 in the San Joaquin valley of Central California. The new and novel variety is an open pollinated hybrid of the ‘Showtime’ plum tree (U.S. Plant Pat. No. 8,037) from which it is distinguished principally by producing a uniformly dark purple skin fruit of medium size and having generally a yellow gold flesh coloration throughout as compared to the red flesh color of ‘Showtime’ with fruit shape more globular with a somewhat more flattened stem end than ‘Showtime,’ ripe for commercial harvest and shipment approximately three to four weeks before the ‘Showtime’ plum tree fruit, and the ‘Early Danae’ remains on the tree up to a high level of maturity.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying drawing is a color photograph showing mature fruit of the new variety of plum tree of the present invention, including fruit showing just the ventral side of the fruit. The second plan shows the stem end (bottom view of the fruit). The third plan shows the apex end. The fourth plan shows the fruit sectioned along the suture plant with the stone removed exposing the flesh and the pit in the cavity. The final plan shows the foliage and twig of the new variety displaying the upper and lower surface of the leaves.
DETAILED DESCRIPTION
Referring to more specific pomological details of this new and distinct variety of plum tree, the following has been observed under the ecological conditions prevailing at the orchard of origin which is located near Parlier in the San Joaquin Valley of Central California.

The above description of this new variety of plum tree is based on the growing conditions prevalent near Parlier, Calif., in the Central San Joaquin Valley of California; variations of the usual magnitude, such as differences in maturity date and production, may be due to cultural practices including irrigation, fertilization, pruning, fruit thinning and primary climate changes. Typical production for a single tree during year 2000 was seven 28-pound cartons.
