Sierra Gem belongs to The Burchell Nursery, Inc., Oakdale, CA (Patent No. 10,810, issued March 2, 1999). The `Sierra Gem` peach tree is characterized as to novelty by producing a freestone fruit which has an attractive orange to reddish blush, and a noteworthy yellow skin coloration with a distinctively attractive yellow-orange stripe in the suture region. Further, the fruit produced by the `Sierra Gem` peach tree is ripe for commercial harvesting and shipment approximately June 12 to June 16 under the environmental conditions existing in the San Joaquin Valley of Central California. The new and novel variety of peach tree is perhaps most closely similar to its parent `Fancy Lady`, (U.S. Plant Pat. No. 7,023), but is distinguishable therefrom and characterized principally as to novelty by producing a high quality, fresh market, freestone, yellow fleshed peach of medium size and which ripens during the second week of June and which additionally possesses a high degree of color with a distinctive yellow-orange stripe in the suture region. In further contrast with the fruit of the `Fancy Lady` peach tree, (U.S. Plant Pat. No. 7,023), the new variety produces fruit which are equal to or slightly larger in size than that produced by `Fancy Lady` peach tree and has a considerably richer flavor than the fruit produced by the `Fancy Lady` peach tree. In addition to the foregoing, the exterior appearance of the new variety and the parent `Fancy Lady` vary substantially. For example, the exterior appearance of the fruit produced by the `Fancy Lady` peach tree is characteristic of most yellow-freestone peach varieties grown in California, that is, it has a mostly orange skin coloration and occasionally, some amount of reddish blush may appear on the skin of the fruit which has been exposed to direct sunlight. In contrast, the new variety of peach has increased amounts of red coloration (blush). Still further, the new variety has, as earlier noted, a distinctive yellow- orange color in the suture.
