| Abstract: |
A new and distinct variety of plum tree which is denominated varietally as "Viking Pride" and which is somewhat similar to the Durado Plum Tree (U.S. Plant Pat. No. 3,925) with which it is most closely related, the subject variety characterized by producing fruit which have a deep red skin color and a yellow flesh color, and which is ripe for commercial harvesting approximately June 13 in the San Joaquin Valley of central California. |
| Claim: |
Having thus described and illustrated my new variety of Plum Tree, what is claimed as new and desired to be secured by Letters Patent is:
1. A new and distinct variety of plum tree substantiallyas illustrated and described which is somewhat similar to the Durado Plum Tree (U.S. Plant Pat. No. 3,925) with which it is most closely related but from which it is distinguished as to novelty by bearing fruit which are large, uniform and a dark redcolor, the fruit ripening for commercial harvesting approximately ten days after the Durado Plum Tree and approximately one week prior to the Black Beaut Plum Tree (U.S. Plant Pat. No. 3,617) which matures at approximately the same time of theseason. |
| Description: |
BACKGROUND OF THE NEW VARIETY
The present invention relates to a plum tree denominated varietally as "Viking Pride", and more particularly to such a plum tree which bears dark red fruit which ripen approximately ten days later than the "Durado" Plum Tree (U.S. Plant Pat. No. 3,925), from which it was derived as a bud sprout, and approximately one week prior to the "Black Beaut" Plum Tree (U.S. Plant Pat. No. 3,615 ), which matures in approximately the same season. The Viking Pride Plum Tree is further characterized asto novelty by producing fruit which has a delicate flavor and a flesh texture which is substantially firmer than the fruit produced by the Durado Plum Tree. In addition the new variety displays noteworthy holding characteristics uncommon to thevarieties with which it is most closely similar.
The Durado Plum Tree is well known as a vigorous producer of early maturing fruit, the fruit of the Durado Plum Tree characterized by a red to dark red skin color and a green-amber flesh; the fruit further being freestone by nature, and havingexcellent eating qualities.
It has long been recognized that it would be desirable to have a plum tree that somewhat remotely resembles the Durado Plum Tree but which bears fruit which are ripe for commercial harvesting later in the season, whereby the commercial demand forsuch a plum can be effectively satisfied over a greater period of time.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The new and distinct variety of plum tree hereof was discovered by the applicant in 1982 as a bud sprout on a Durado Plum Tree, the subject tree growing in a commercial orchard owned by the applicant and located on Magnolia Avenue in Kingsburg,Calif. The bud sprout was noted at that time to have desirable characteristics. Scion wood of the new variety was subsequently taken by the applicant in February, 1985 and grafted onto Nemagard root stock seedlings. It has been subsequently determinedthat this first asexual propagation resulted in progeny being produced that possess the same distinctive characteristics as the original bud sprout.
SUMMARY OF THE NEW VARIETY
The Viking Pride variety of plum tree is characterized as to novelty by producing fruit which are mature for commercial harvesting approximately ten days later than the Durado Plum Tree (U.S. Plant Pat. No. 3,925) and about one week prior tothe Black Beaut Plum Tree (U.S. Plant Pat. No. 3,617), both plum trees maturing in approximately the same season. The fruit of the subject plum tree is further characterized as to novelty by producing fruit which have a dark red skin color, a yellowcolored flesh and a delicate flavor.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawing is a color photograph of four mature fruit of the subject variety, one of which has been divided in the suture plane to show the flesh characteristics, together with a twig bearing typical leaves showing the dorsal andventral coloration thereof, and two stones, all of the subject variety.
DETAILED DESCRIPTION
Referring more specifically to the 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 the inventor which is located on Magnolia Avenuenear Kingsburg, Calif. All major color code designations are by reference to the Dictionary of Color by Maerz and Paul, Second Edition, 1950. However, common color names are also employed occasionally.
