A plum tree generally similar to the santa Rosa plum tree (unpatented) which it most nearly resembles, ripening twenty days earlier than the santa Rosa, and bearing fruit having medium red skin and mild, delicately-flavored flesh.

1. A new and distinct variety of plum tree substantially as illustrated and described and broadly characterized by the ripening of its fruit approximately twenty days earlier than that of the unpatented santa Rosa plum tree, which it most nearly resembles, but further differing therefrom in its regular and productive bearing of fruit having larger average size and firmer flesh when eating ripe, and the greater vigor of its tree.

The present invention relates to a new and distinct variety of plum tree broadly characterized by its productive, regular bearing of uniformly medium-sized fruit which has firm flesh which clings to the stone, and ripens twenty days earlier than the fruit of the unpatented Santa Rosa plum tree, which it most nearly resembles.
The factors contributing toward the commercial acceptance and success of any variety of plum tree are myriad. However, it is well known that the visual appearance of a plum is one of the primary motivating elements involved in a consumer's decision to purchase one type of plum rather than another. Further, it is well known that a plum that combines the desirable characteristic of visual asthetic appeal with the complementary attribute of having firm, meaty flesh of delicate flavor, is one which possesses a strong chance of becoming the object of repeated purchases by individual consumers thereof.
It has long been recognized as desirable to provide a plum tree variety which bears fruit having these desirable characteristics, and further having a uniform, symmetrical shape and attractive, even coloration. This is particularly so when such a plum ripens earlier than the plums sharing generally similar characteristics, thus affording the new variety an advantage in competition with other, similar varieties. Such early ripening also benefits consumers by extending the period during which consumers can avail themselves of several varieties having general characteristics in common.
My new variety of plum tree was discovered by me in 1968 as a seedling of unknown origin. The seedling was discovered on a ranch which was then and is now owned by me and which is located at the corner of Church and Greenwood Avenues, near the City of Sanger, in the County of Fresno, in the State of California.
I continued to observe the young seedling and asexually reproduced it in 1971 by budding it onto seedling stock. Such asexual reproduction was first conducted on a ranch then and now owned by me at the corner of Kings Canyon Road and Fowler Avenue, in the City of Fresno, in the County of Fresno, in the State of California. Fruit and tree characteristics of plum trees resulting from such budding proved to be identical to those of the original new growth.
The instant variety of plum tree is generally characterized by bearing uniformly medium-sized fruit, having nearly full colored, medium red skin, and which ripens approximately twenty days earlier than the fruit of the unpatented Santa Rosa plum tree, which it most nearly resembles. The fruit of the instant variety further distinguishes itself from the Santa Rosa plum by its larger average size and firmer flesh. Additionally, the tree of the present variety is more vigorous than that of the Santa Rosa.
The fruit of the new variety is uniformly medium in size, and is uniform to slightly variably symmetrical in form. The fruit has firm, meaty flesh, mild and delicate in flavor, and adheres to the stone over the entire surface thereof.
The new variety is especially characterized by its nearly fully colored, medium red skin, and its large, vigorous tree which is a regular, productive bearer of its fruit.
The accompanying drawing is a color photograph of a representative twig bearing a plum with the bloom characteristic of the new variety and bearing leaves characteristic of the new variety; three plums, two showing the base aspect, and one showing the suture aspect; and a plum divided to show the flesh color and the stone.
Referring more specifically to the pomological details of this new and distinct variety of plum tree, the following characteristics have been observed under the ecological conditions prevailing at the designated orchard in Fresno County, Calif.
