DESCRIPTION OF THE VARIETY

A cross between the female variety Sugargate and the pollen parent variety Senoia.

The primary objective of the breeding was to produce an improved variety of muscadine grape. The fruit of the new variety is large and bronze and has a dry stem scar. Other fruit characteristics of the new variety include even ripening, high sugar content and long shelf life. The new variety is self-fertile, as well as productive and vigorous.

In comparison with both the seed and the pollen parent, the new variety is similar in size to the seed parent and resembles in color the seed parent. The new variety is larger than the pollen parent. The fruit of this new variety contains on the average of from 20 to 21 percent soluble solids, which sugar content is higher than the pollen parent. The present variety yields approximately 4 to 6 tons per acre in tests conducted at Ison's Nursery & Vineyards, Brooks, Ga. The taste of this fruit is outstanding, having an excellent flavor.

Asexual reproduction of the new variety either by soft wood cuttings or by layering as performed at Brooks, Ga. shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying photograph shows a typical specimen of the vegetative growth and fruit of the new variety when the fruit is ripe and ready for picking and as depicted in color as nearly true as it is reasonably possible to make the same in color illustration of the characteristics.
