<p>Damping-off of broccoli was observed in Hokkaido, Japan in late-May 2012. An isolate obtained from diseased tissues was identified as Rhizoctonia solani anastomosis group(AG)-2-1 on the basis of hyphal anastomosis and the result of PCR analysis with specific primers. The cultural appearance of the isolate from broccoli was light brown, whereas that of typical AG-2-1 culture type Ⅱ was brown. Also the mycelial growth of the isolate was slower than that of typical culture type Ⅱ. The AG-2-1 isolate and six reference isolates, belonging to culture type Ⅱ obtained from various Brassica plants, caused basal stem rot in broccoli seedlings in inoculation tests, indicating that pathogenicity to broccoli seedlings is the universal characteristic of AG-2-1 isolates as well as of the light-brown and slow-growing isolate. As no damping-off of broccoli caused by R. solani AG-2-1 has not been reported in Japan, we hereby propose including it as one of the pathogens of the disease.</p>
