Narrative
Daisui Li (12-44) - A large, smooth skinned, pyriform shaped Asian pear developed in California. Orig. at UC Davis, by Ben Iwakiri and evaluated as selection '12-44' near Winters, California. Plant Patent 6075 issued in 1988 to the University of California. A cross between the Japanese cultivar Kikusui and the Chinese cultivar Tse Li (Tsu Li). Fruit: large to very large, obovate to globular, more pear-shaped than most Asian cultivars, including sister cultivar Shin Li. Smooth thick skin is light green at maturity. Flesh: white, firm, coarse, crisp, juicy, sweet and subacid. Ripe early September in Davis, California. Distinct aroma similar to Tse Li. Fruit stores 5-6 months at 0 C. Tree: large, upright to slightly spreading, open, hardy, more vigorous than other Asian cultivars. Leaves: large, wide and leathery. Blooms with Chojuro and Kikusui, slightly later than Ya Li and Tse Li, earlier than Bartlett. Resistant to fire blight.
