Abstract
An Asian pear tree which is of large to medium size, vigorous, upright to slightly spreading, tall, open, medium growing and hardy; foliated with large, wide, long, medium thick, leathery, ovate leaves having acuminate apices, a margin with sharply setose serration, and a petiole of medium length and thickness; blooms early with white, medium size, fertile flowers; and is a regular and productive bearer of large to very large, obovate to globular fruit having skin which is smooth, thick to medium thick, and medium green to light green at maturity, and white flesh which is firm, somewhat coarse, crisp, tender, juicy, sweet, and subacid with a trace of tartness.
Description
In the conduct of an extensive plant breeding program, I originated a substantial number of new and distinct varieties of fruit trees, and which included the herein-claimed variety of Asian pear tree; such plant breeding program having been undertaken by me at the University of California, Davis, Yolo County, Calif., in its research nursery, and in one of its experimental orchards.
The present variety of Asian pear tree (identified by test selection number "12-44") is embraced by Class 36, Plants, of the U.S. Patent Office Manual of Classification.
Among existing varieties which are known to me, and mentioned herein, are the Asian pears Kikusui, Tsu Li, Ya Li, Shinko, and Chojuro; and the domestic Bartlett.
The present variety of Asian pear tree was originated by me in the aforesaid experimental nursery and orchard as a cross between the Kikusui and Tsu Li varieties of Asian pears. A substantial number of the resulting seeds were initially grown in a greenhouse, then in the nursery, and later transplanted to an experimental orchard near Winters, Calif., where such seedlings were maintained under close and continuing observation. Upon bearing fruit, one of such seedlings evidenced certain novel and distinctive characteristics and was selected for asexual reproduction, with a view toward possible ultimate commercial introduction.
Subsequent to its origination and selection, as above, the herein-claimed variety of Asian pear tree was asexually reproduced by me by top-grafting on compatible pear seedlings in the aforesaid experimental orchard and, in maturity, the reproductions ran true to the original tree in all respects.
The herein-claimed variety of Asian pear tree is of large to medium size, vigorous, upright to slightly spreading, tall, open, medium growing, and hardy; foliated with large, wide, long, medium thick, leathery, ovate leaves having acuminate apices, a margin with sharply setose serration, and a petiole of medium length and thickness; blooms early with white, medium size, fertile flowers; and is a regular and productive bearer of large to very large, obovate to globular fruit having skin which is smooth, thick to medium thick, and medium green to light green at maturity, and white flesh which is firm, somewhat coarse, crisp, tender, juicy, sweet and subacid with a trace of tartness.
The herein-claimed variety of Asian pear tree is further, and more particularly, characterized by a tree which is compatible with all pear rootstocks and grows more vigorously on them than other Asian pear varieties; blooms slightly after the Ya Li and Tsu Li and more nearly with the Chojuro and Kikusui, but earlier than the Bartlett; and by the regular and productive bearing of large to very large fruit (which minimizes thinning) which becomes picking and eating ripe after the Bartlett and the Shinko; the fruit being more pear-shaped than most Asian pear varieties, including Asian pear selection "12-43" which is the subject of my U.S. plant patent application Ser. No. 06/814,248 filed 12/27/85. Additionally, the fruit--of excellent quality--has a smooth, clean appearance, and the white flesh (soluble solids 14%) is refreshingly mild; the fruit having a storage life of five to six months at 32° F.
The drawing is an illustration, by photographic reproduction in color, of separate fruit of the variety; certain of the fruit being shown whole, while other fruit is half cut-away to expose the flesh.
