Abstract
A new and distinct variety of grapevine is provided which abundantly forms attractive medium-to-large seedless berries having a rose-pink skin coloration in medium-to-large substantially uniform clusters. The fruit displays a sweet crisp flavor and is firm in texture. The fruit commonly is ready for harvest during late October or early November in the San Joaquin Valley of Central California, U.S.A., and displays significant crispness and good eating qualities as a table grape. The fruit firmness renders the fruit well amenable for handling, shipping, and storage. The fruit commonly is more elongated and less round and lighter in coloration than that of the ‘Mara Seedless’ variety (U.S. Plant Pat. No. 19,599).
