A new and distinct hybrid plum tree named DA 6 developed for use as a rootstock and notable for the reduced vigor imparted to scions, good root strength, tolerance of wet soils and resistance to root-knot nematodes.

The present invention relates to a plum tree and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, and productive tree. Being self-unfruitful, the present variety requires cross pollination from another plum or interspecific tree that blooms during the mid to late season, such as Plumsweet X interspecific tree (U.S. Plant Pat. No. 19,528). The present variety's abundance of blossoms and moderate pollen production entices strong bee activity to facilitate pollination. The fruit matures under the ecological conditions described during the second week of September, with first picking on Sep. 13, 2018. The fruit is uniform, medium in size, almost full red in skin color, clingstone in type, red to pink in flesh color, firm in texture, juicy, very sweet and excellent in flavor.

A new and distinct plum tree variety, Prunus salicina, cv. Suplumfiftysix is characterized by having very large fruit, with reddish-black skin and red flesh. The fruit of the new variety Suplumfiftysix also has firm flesh, a sweet-mild flavor and a stone that is semi-free from the flesh. The date of ripening of the fruit of the new variety is approximately September 7.

A new and distinct plum tree variety, Prunus salicina, cv. Suplumfiftyfive is characterized by having early-ripening fruit that is large, with black skin and red flesh. The fruit of the new variety Suplumfiftyfive also has firm flesh, a sweet-mild flavor and a stone that is semi-free from the flesh. The date of ripening of the fruit of the new variety is approximately June 10.

A new prune cultivar designated UC G2S-8 has been developed. The fruit of this cultivar are medium, yellow in color and covered with a grayish waxy bloom. The UC G2S-8 tree is productive and a regular bearer.

The present invention relates to a plum tree and more particularly to a new and distinct variety broadly characterized by a small size, medium vigorous, hardy, and very productive tree. Being self-unfruitful, the present variety requires cross pollination from an apricot, interspecific, or plum that blooms during the late season, such as Plumred VII interspecific tree (U.S. Plant Pat. No. 23,688). The present variety produces a heavy amount of bloom with a moderate amount of pollen to entice good bee activity to facilitate pollination. The fruit matures under the ecological conditions described during the last part of September, with first picking on Sep. 25, 2017, and will hang on the tree an additional thirty days. The fruit is uniformly medium in size, dark purplish red in skin color, dark red in flesh color, clingstone in type, mostly ovate in shape, firm in texture, very sweet, and outstanding in flavor.

The present invention relates to a plum tree and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, and very productive tree. Being self-unfruitful, the present variety requires cross pollination from another plum or interspecific tree that blooms during the mid to late season, such as Plumsweet XV interspecific tree (U.S. Plant Pat. No. 23,687). The present variety's abundance of blossoms and moderate pollen production entices strong bee activity to facilitate pollination. The fruit matures under the ecological conditions described during the first week of September, with first picking on Sep. 5, 2017. The fruit is uniform, very large in size, nearly black in skin color, clingstone in type, full yellow in flesh color, firm in texture, juicy, and excellent in flavor.

A new and distinct variety of interspecific tree. The following features of the tree and its fruit are characterized with the tree budded on Nemaguard Rootstock (non-patented), grown on Handford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consist of the following combination of desirable features: 1. Tree having a vigorous, upright growth habit. 2. Tree being a regular and productive bearer of medium to large size fruit. 3. Fruit having firm, white flesh with very good flavor and eating quality. 4. Fruit with an attractive mottled red skin color. 5. Fruit with good storage and shipping quality.

A new and distinct plum tree variety, Prunus salicina, cv. Suplumfiftyone is characterized by having large fruit with dark red flesh. The fruit of the new variety Suplumfiftyone is also moderately firm, juicy and has a mild sweet flavor. The date of the harvest of the fruit of the new variety is later than for Black Splendor (unpatented). The fruit of the new variety Suplumfiftyone ripens with nearly same timing as the fruit of Friar (unpatented) but has a dark red flesh compared to yellow-colored flesh for the fruit of Friar.

A new and distinct plum tree variety, Prunus salicina, cv. Suplumfiftythree is characterized by having large, juicy fruit with black skin and red flesh. The fruit of the new variety Suplumfiftythree also has a high Brix:Acid ratio, firm flesh, a mild sweet flavor and a stone that clings to the flesh. The date of ripening of the fruit of the new variety is later than for Black Splendor (unpatented) and earlier than Owen-T (unpatented). The fruit of the new variety Suplumfiftythree is larger than the fruit of Black Splendor and smaller than the fruit of Owen-T.
