T he cross was made in 1986. The female parent was Steuben and the pollen parent was a bulk collection from a set of Neotuberosum-tuberosum hybrids. The neotuberosum population was developed from cultivated clones grown in the South American Andes. Eva was first evaluated as K88-24, then as NY 103. The tubers are well shaped, have shallow eyes and a bright white skin.
Tubers are almost free of internal defects and pickouts.
The chip color is acceptable. The specific gravity is about .013 less than Atlantic. Tuber set is slightly greater than Katahdin and size is slightly smaller. Tuber dormancy is exceptionally long, seven weeks longer than Katahdin or Atlantic to produce sprouts. Precutting or warming seed is recommended.
