摘要：
Sclerotinia crown and stem rot is the most destructive disease on red clover in areas with cool seasons including North America and Europe. An artificial inoculation test in controlled conditions has been developed in order to evaluate resistance to this fungus in individual plants. Measured drops of ascospore suspension were applied to detached clover leaflets and disease severity scored on a visual scale. Clovers from 16 cultivars and 12 ecotypes were tested for resistance to Sclerotinia trifoliorum. The results obtained for cultivar resistance are in agreement with those of other tests described in the literature. Moreover, repeated individual evaluations on detached leaflets from the same plant was successful in detecting genotypic variation within clover populations.
