identification: Medium size, round to round-conic with faint ribbing on the sides. The base colour is golden yellow with a faint orange blush over which is a dense pattern of orange-red stripping on the sun exposed face. The eye is large and open, set in a medium deep, wide and slightly ribbed basin. The stem is medium length, medium stout and set in a funnel-shaped, russetted cavity with rays of russetting extending over the shoulder of the apple. Medium thick skin

origins: Bred in 1999 under the direction of Dr. Jaroslav Tupý at the Institute of Experimental Botany in Prague (Czech Republic) by crossing
Golden Delicious with pollen from
Topaz . Released in 2006.
cultivation: Moderately vigorous, spreading. Grows fruit on short spurs and one-year-old wood. A slight tendency to produce fruit every other year. Does best in well-irrigated, and sunny conditions and a good choice for growing on hillsides. Some light fruit thinning is necessary for the best harvests and also to overcome its tendency to bear biennial harvests.
