Study Name: Resistance to Verticillium Wilt. Experiment Type: Field FIELD Study Year: 1984 Year started: 05/15/1984 Year ended: 12/10/1984. Ten seedlings were inoculated by putting five milliliters of a Verticillium dahliae inoculum into the root zone with a syringe. Two days after inoculations, the plants were put into the field. Accessions were rated by squeezing the sap out of a potato stem into a petri dish and adding a diagnostic medium. Four individual plants were then analyzed for Verticillium propagules.
