Abstract
A new and distinct cultivar of early-season clingstone peach tree (i.e., Prunus persica) is provided. Attractive fruit is formed that is well suited for processing having uniform yellow flesh that is free from red staining at the pit cavity. The fruit color, flavor, and texture are believed to be superior to the "Dixon' and "Andross' cultivars (both non-patented in the United States). The fruit ripens at approximately four days earlier than the "Andross' cultivar. The pink flowers are medium-sized and non-showy and the growth habit is upright-spreading.
