Abstract
A new and distinct variety of plum tree Prunus Salicina derived as an open pollinated hybrid from the ‘Red Beaut’ plum tree (U.S. Plant Pat. No. 2,539), but from which it is distinguished by producing fruit of high quality having a distinctive flavor, a generally green skin coloration and regular bearing, the variety developed as a hybridized seedling from the aforementioned selected seed parent and an unnamed seedling as the selected pollen parent.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
Having thus described and illustrated my new variety of plum tree, what I claim as new and desire to be secured by Plant Letters Patent is: 1. A new and distinct variety of plum tree substantially as illustrated and described which is somewhat similar to the “Red Beaut” plum tree (U.S. Plant Pat No. 2,539) and relative to ripening date, but from which it is well distinguished in numerous respects by producing fruit which are mature for commercial harvesting and shipment approximately May 17 to May 24, in the San Joaquin Valley of central California while having a generally green skin coloration and productivity as opposed to the fruit of the aforementioned plum variety.
