Abstract

The present invention relates to a plum tree, Prunus salicina, and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, hardy, self-unfruitful, usually productive tree. The fruit matures under the ecological conditions described during the third week in June, with first picking on Jun. 17, 2001. The fruit is uniformly medium in size, excellent in flavor, globose in shape, clingstone in type, very firm in texture, yellow in flesh color, and dark red to purple in skin color. The variety was developed as a first generation cross using ‘Grand Rosa’ (U.S. Plant Pat. No. 1,756) as the selected seed parent and an unnamed plum seedling as the selected pollen parent.

Description

BOTANICAL CLASSIFICATION
Prunus salicina.
BACKGROUND OF THE VARIETY
In a continuing effort to improve the quality of shipping fruits, I, the inventor, typically hybridize a large number of peach, nectarine, plum, apricot, and cherry seedlings each year. The present invention relates to a new and distinct variety of plum tree, which has been denominated varietally as ‘YUMMYBEAUT’. The present variety was hybridized by me in 1995, germinated and grown as a seedling on its own root in my greenhouse, and transplanted to a cultivated area of my experimental orchard at Bradford Farms near Le Grand, Calif. in Merced County (San Joaquin Valley). Specifically, the variety was developed from a first generation cross using ‘Grand Rosa’ (U.S. Plant Pat. No. 1,756) as the selected seed parent and an unnamed plum seedling as the selected pollen parent. Subsequent to origination of the present variety of plum tree, I asexually reproduced it by budding and grafting in the experimental orchard described above, and such reproduction of plant and fruit characteristics were true to the original plant in all respects. The reproduction of the variety included the use of ‘Nemaguard’ rootstock (unpatented) upon which the present variety was compatible and true to type.
The present variety is similar to its seed parent, ‘Grand Rosa’ (U.S. Plant Pat. No. 1,756), by producing dark red plums that are firm in texture, globose in shape, and dark red in skin color, but is very distinguished therefrom and an improvement thereon by ripening about 8 weeks earlier.
The present variety is most similar to ‘Black Beaut’ (U.S. Plant Pat. No. 3,617), by being self-unfruitful and producing dark red plums that are globose in shape and that mature during the middle of June, but is distinguished therefrom and an improvement thereon by producing an abundance of pollen and by producing fruit that is firmer in texture, sweeter in flavor, and has no red bleeding in the flesh. Being self-unfruitful, the present variety requires an early blooming cross pollinator, such as ‘Ambra’ (unpatented). Additionally, the present variety's abundance of pollen entices strong bee activity to its blossoms to facilitate pollination, contrary to ‘Black Beaut’, which produces virtually no pollen.
DRAWING
The accompanying photograph exhibits four whole fruits positioned to display the characteristics of the skin color and form, one fruit divided transversely to the suture plane to reveal the flesh and stone, and typical leaves.
POMOLOGICAL CHARACTERISTICS
Referring now more specifically to the pomological characteristics of this new and distinct variety of plum tree, the following has been observed under the ecological conditions prevailing near Le Grand, Merced County (San Joaquin County), Calif., and was developed at the state of firm ripe on Jun. 21, 2001, on the original tree during its sixth growing season. All major color code designations are by reference to the Inter-Society Color Council, National Bureau of Standards. Common color names are also used occasionally.
