Abstract
A new and distinct variety of plum tree ( Prunus salicina ). The following features of the tree and its fruit are characterized with the tree budded on ‘Nemagaurd’ 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 consists of the following combination of desirable features: 1. Fruit ripening in the late maturity season. 2. Fruit holding firm on the tree 2 weeks after maturity (shipping ripe). 3. Fruit with a high Brix of 18.7°. 4. Fruit with very good storage. 5. Heavy and regular production of fruit. 6. Fruit with relatively uniform large size fruit throughout the tree.
