Abstract :
Eleven sugar beet genotypes were evaluated at National Agricultural Research Centre, Islamabad, Pakistan, during the year 2009 for their resistance against root rot caused by Sclerotium rolfsii. The fungus was isolated from infected beet root, purified and maintained on Potato Dextrose Agar at 4°C for further experimentations. Mass culturing of pathogen was prepared through sorghum seed inoculum technique. Inoculation of eleven genotypes with S. rolfsii exhibited resistant response only in SD-PAK-09/07 and moderately resistance in SD-PAK-07/071. The remaining nine genotypes showed susceptible to highly susceptible response to the pathogen.
