Abstract

A new and distinct variety of plum tree which is somewhat remotely similar to the ‘Angeleno’ plum (unpatented), but from which it is distinguished therefrom by fruit for harvesting and shipment approximately the three to five days earlier than the fruit produced by the ‘Angeleno’ plum tree, but which further produces a high quality, fresh market plum of medium size with a dark purple to burgundy colored skin and red flesh of exceptional eating quality and good storage characteristics.

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 ‘Danae’ and more particularly to a plum tree which produces fruit which are mature for commercial harvesting and shipment approximately the first week of September in the San Joaquin Valley of Central California, and which is further distinguished as to novelty by producing a freestone fruit which has a flavor superior that of late maturity commercial plum varieties and which has a coloration having a dark purple to burgundy characteristic and red colored flesh.
There are a number of criteria within which a commercial variety of tree fruit must excel if it is to be a success in the fresh market. Among these are ripening date, flavor, texture, shipping quality and similar characteristics. Another factor or factors are coloration and size of the fruit. Typically fruit that is of high coloration and good size is commercially desirable in that it is attractive and thereby appealing to the consumer. More subtly high coloration, if different than competing commercial variety, attracts immediate attention in the market place which substantially increases the likelihood of commercial success.
Fresh market plums are characterized as the coloration typically by shades of yellowish green to red to dark purple to black with flesh colors varying from yellow or amber to various shades of red. The plum fruit may vary from being a clingstone to semi-freestone to freestone with freestone being the preferred characteristic. Of critical importance in plum varieties of fruit are good size and holding quality along with good eating quality.
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 ‘Danae’ plum tree is characterized as to novelty by producing a freestone fruit which has a dark purple to burgundy skin coloration with red flesh. The fruit produced by the ‘Danae’ plum tree is ripe for commercial harvesting the first week of September in the San Joaquin Valley of Central California. The new and novel variety is perhaps more closely similar to the ‘Angeleno’ plum tree (unpatented) but is distinguishable therefrom and is characterized as a high quality fresh market plum of medium size ripening in the first week of September and possessing an unusually excellent flavor and excellent handling and shipping characteristics. This new variety is equal to or slightly larger than ‘Angeleno’ but is substantially superior to the ‘Angeleno’ in flavor. The new variety has substantially better or richer flavor and is well balanced. The ‘Danae’ produces fruit about six weeks later than ‘Showtime’ (U.S. Plant Pat. No. 8,037). The ‘Danae’ fruit is smaller in size and has better holding capacity than ‘Showtime,’ and the flesh has a clear ground color as opposed to red for ‘Showtime.’
The exterior of this new variety has coloration similar to ‘Angeleno’ but the flesh has a red coloration and good fumes. Because of the exceptional flavor and the freestone nature this plum will have greater consumer acceptance.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying drawing is a color photograph of mature fruit of the new variety showing several in top view, a second in side elevation displaying the suture, several fruit showing the side thereof 90 degrees from the suture, a fourth sectional along the suture and laid open to expose the stone alone with both halves displaying the stone well, and finally portions of representative foliage, and terminal twigs and branches.
