Description

ORIGIN OF THE VARIETY

The present new and distinct variety of peach tree was originated by us in our experimental orchard located near Modesto, Calif., as a third generation cross between two selected seedlings, identification numbers 47EB280 and 1GC131. The maternal parent 47EB280 originated from a cross between two selected seedlings, 29G560 and 17G185. The selected seedling 29G560 originated from a cross of O'Henry Peach (U.S. Plant Pat. No. 2,964) with Giant Babcock Peach (U.S. Plant Pat. No. 1,353); and the selected seedling 17G185 originated from a cross of Fayette Peach (non-patented) with May Grand Nectarine (U.S. Plant Pat. No. 2,794). The paternal parent 1GC131 also originated from a cross between two selected seedlings, 41G1176 and 42G280.The selected seedling 41G1176 originated from an open pollinated peach seedling of unknown parentage and the selected seedling 42G280 originated from an open pollinated seedling selection of May Grand Nectarine (U.S. Plant Pat. No. 2,794). We grew and maintained a large group of these third generation seedlings under careful observation, during which time one such seedling, which represents the present variety, having especially desirable fruit characteristics, was selected for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

The present new variety of peach tree was asexually propagated by budding, as performed by us in our experimental orchard located near Modesto, Calif. which shows that said characteristics of the tree and its fruit are established and transmitted through succeeding asexual propagation and comes true to the original tree in all respects.

SUMMARY OF THE VARIETY

The herein described variety of peach tree is of large size, vigorous, upright growth and a productive and regular bearer of large white flesh, clingstone fruit with very good flavor and eating quality. The fruit is further characterized by being relatively uniform in size throughout the tree, having an attractive red skin color, firm white flesh, with good handling and shipping qualities. The fruit ripens in the early maturity season, approximately one week before Sugar May Peach (U.S. Plant Pat. No. 8,034).

PHOTOGRAPH OF THE VARIETY

The accompanying color photograph shows a reproduction of the foliage and fruit of the new variety of peach tree. The illustration is of the upper and lower surface of the leaves; an exterior and sectional view of the fruit divided in the suture plane to reveal flesh coloration, pit cavity and a stone remaining in place.
