摘要：

An inoculation method using Lupinus luteus was developed for estimating virulence of isolates of the white root rot fungus, Rosellinia necatrix Prillieux. Fungal cultures grown on pieces of mulberry twigs were placed in contact with the hypocotyl of 3-week-old seedlings growing in pots of soil. Disease development was uniform and reproducible in repeated experiments. Of 24 isolates with double-stranded RNA, eight were weakly virulent. This method is useful throughout the year for estimating virulence of many isolates of the fungus and for screening for hypovirulent isolates.
