The present variety of grapevine was discovered during the 1978 growing season in a vineyard on Rancho Primero, located south of Coachella, Riverside County, Calif. The description of the characteristics was made during the 1979 and 1980 growing seasons. The grapevine was discovered as a sport of Superior Seedless (U.S. Plant Pat. No. 3,106). In the spring, the present variety of grapevine manifested an earlier bud break and shoot growth than the surrounding Superior Seedless grapevines. Throughout the season, the sport vine, which closely resembles the Superior Seedless variety, maintained the advanced growth and period of cluster ripening. The present variety has distinctive new growth habits which class it as a special table grape. The Superior Seedless variety is a cross between the Cardinal and an unnamed seedless sport (unpatented) with a complex parentage. The appearance of the present variety indicates an expression in the generation manifestation of a dominant character gene previously unnoticed in the Superior Seedless variety.
