Study Name: Resistance to Verticillium Wilt. Experiment Type: Field FIELD Study Year: 1983 Year started: 05/15/1983 Year ended: 12/14/1983. 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. The average number of propagules were computed for each accession.
