OTHER INFORMATION: Grown commercially in New Zealand in the 1960's and 1970's, but not grown commercially any more. Sister selection of First Choice (USDA 66055). A tetraploid Smooth Cone was developed at the Riwaka Research Station in the late 1970's by colchicine treatment. It was used to develop the triploid superalpha hops Green Bullet (USDA 21404), SuperAlpha (USDA 21405>, and Alpharoma (USDA 21406), which are now the predominant hops grown in New Zealand.
