Botanical Features

Agricultural Features

Very high yielding full season variety. Medium-long dormancy. Medium-high specific gravity. Susceptible to harvest damage. Vines are difficult to kill. For adequate tuber maturity and good skin set, at least three weeks should be allowed between vine desiccation and harvest. Excessive harvest injury (and resultant fusarium dry rot in storage) can occur if tubers are harvested too soon after wine kill. Tuber bulking rate is rapid during the latter part of the growing season and careful attention is required to avoid excessive tuber size. Use low rates of nitrogen and close spacing to avoid oversize.

Good resistance to hollow heart, brown centre and other internal defects. Uniform tuber shape, high yields of count carton sizes, and attractive appearance make it well suited for the fresh market industry.

Reaction to Diseases

Highly resistant: verticillium wilt, PVX.
Moderately resistant: common scab and foliar early blight.
Susceptible: PVY, leaf roll, fusarium dry rot, Erwinia soft rot.
Highly susceptible: tuber early blight.

NOTE: PVY infection results in severe symptoms that significantly reduce yields.
