Summary

Sclerotinia crown and stem rot is a destructive disease on red clover. In this study we investigated appropriate procedures for producing and storing ascospores in the laboratory and compared the reaction of selected red clover germplasm, when inoculated with either ascospores or mycelium. The two methods produced fairly similar results, although there were exceptions. The procedures described to produce, store and inoculate with ascospores, will provide an opportunity to select germplasm resistant toSclerolinia trifaliorum ascospores as inoculum.
