Plum tree, Suplumfourteen
BACKGROUND OF THE VARIETY 
     The present invention relates to a new and distinct variety of plum tree which has been named &#34;Suplumfourteen&#34; for commercial marketing. The new variety is broadly characterized by its general resemblance to the Santa Rosa variety of plum tree (unpatented), but distinguished therefrom by its fruit being of larger size, having a more purple skin coloration, having a relatively ovoid form with a relatively flattened and broader base, with shoulders slanted more toward the apex, and with an apex which is a rounded point rather than a depression. The present variety is further distinguished from the Santa Rosa variety by the present variety bearing fruit which attains a fully reddish flesh coloration when relatively immature, has a superior shipping and keeping quality, has flesh which is substantially less acid, and has a slower ripening quality so that fewer pickings are required and the marketing period is longer. 
     More fresh plums of the Santa Rosa variety are shipped commercially in the state of California than plums of any other variety due to such reasons as the attractive appearance and excellent flavor of plums of this popular variety. However, fruit of the Santa Rosa variety is deficient in that its flesh is highly acid and that its shipping and keeping quality is relatively poor. A slow ripening quality is desirable in fresh fruits, thereby extending the marketing period in that the fruit remains suitable for consumption over a longer period of time. It is desirable that fresh fruits attain their fully mature coloration early so that they may be harvested as soon as possible. 
     ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY 
     The subject variety of plum tree was discovered during a plant breeding program conducted by me for the Superior Farming Company, a corporation of Nevada. During this program, open pollinated seeds of the Angeleno variety of plum tree (U.S. Plant Pat. No. 2,747) were grown to fruition, and trees from such seeds showing desirable characteristics were, under my direction, selected and propagated by budding onto other trees or rootstocks. The subject variety was discovered on June 24, 1979. Upon asexual reproduction of the subject variety, as performed in that year, it was found the tree and fruit characteristics which resulted were identical to those of the one tree. The above-designated program, which resulted in the subject variety, was carried on in a breeding orchard owned by Superior Farming Company and located at 5090 East Church Avenue, near the City of Fresno, in the County of Fresno, and in the state of California. 
     SUMMARY OF THE NEW VARIETY 
     The subject variety of plum tree is similar to the Santa Rosa variety (unpatented) in that the varieties ripen at the same time, bear fruit having a purplish-reddish skin coloration and having pinkish or reddish flesh when fully ripe. However, plums of the subject variety are distinguished from those of the Santa Rosa variety in having a form which is somewhat ovoid, rather than globose, as in the Santa Rosa, and having a flatter, broader base and shoulders slanted more toward the apex, the apex of the subject variety being a short, rounded point rather than being depressed as in the Santa Rosa. The skin coloration of the subject variety is relatively more purple and less red than that of the Santa Rosa. Fruit of the subject variety is more particularly distinguished from that of the Santa Rosa variety by being 5-10 millimeters larger in diameter, by having flesh which acquires a fully red coloration from skin to stone when the fruit is relatively immature rather than being yellow until fully ripe as in the Santa Rosa, and by fruit of the subject variety having a slower ripening quality giving it a longer marketing period than fruit of the Santa Rosa variety. The subject variety is especially distinguished from the Sant Rosa variety in bearing plums having a superior keeping and shipping quality and having a flesh which is less acid.

     DETAILED DESCRIPTION 
     Referring more specifically to the subject variety of plum tree, the following is a horticultural description of characteristics thereof resulting from the growing conditions in the above-identified orchard located in the San Joaquin Valley of California. It is to be understood that variations of the usual magnitude incident to growing conditions, fertilization, pruning, and pest control are to be expected in such characteristics. In the following description, color plate references are to the &#34;Plochere Color System&#34;, which is published in Los Angeles, Calif., common descriptive color terms also being employed.
