Sun Valley has a large frame with a medium yellow color, a brilliantly thick smooth tapered midrib, and has excellent weight at harvest time. It is corky root resistant, has strong bolting tolerance, plus it has a strong resistance to low & high temperature abnormalities. Plant height is 11.5 to 13 inches long with a thick wide leaf surface. Because of its large frame and high tolerance to tip-burn Sun Valley may be used for Fresh, Processor, and possibly Heart markets.
