1. ZC 9854A was selected for resistance to the following pests: bacterial wilt, Fusarium wilt, Verticillium wilt, Phytophthora root rot, anthracnose (race 1) and Aphanomyces root rot (races 1 and 2). Phenotypic recurrent selection was used. Final selections were made from 2-3 year old space plant selection nurseries near Larned, Kansas, Napier, Iowa and Livingston, Wisconsin based on yield, winter survival, fall dormancy, leafhopper yellowing and leaf disease. Breeder seed (syn 1) was produced in 1998 near Nampa, Idaho on approximately 25 cuttings of each clone transplanted at random and harvested in bulk.

2. ZC 9854A is adapted to the North Central and East Central Regions of the U.S. It is intended for use in the North Central and East Central Regions of the U.S. It has been tested in Iowa, Wisconsin, and Illinois.
