Abstract
Six commercial and 20 candidate line of sesame were screened during 2012-2013 against M. phaseolina. Resistance response of Sesame germplasms was determined in pots and field under natural conditions. Sick field was prepared by mixing test pathogen at the rate of 0.4% on the upper soil layer. Observation regarding resistance reaction of test germplasms was recorded by observing charcoal rot incidence at maturity using 0-9 visual rating scale. Results demonstrated variation in response of test germplasms to charcoal rot and none of the variety or line was found immune. In pot experiment seventeen varieties/lines were highly susceptible, three were moderately resistant while six varieties/lines showed susceptible reaction. On the basis of varietal response in pot experiment nine varieties were selected for screening in field experiment against M. phaseolina. The only line that exhibited 1-10% mortality in field was 87008, lines 87502 and 95002 were moderately resistant while 20011, black till, TS3 and 98002 showed susceptible response. The variety TH6 and candidate line 40009 exhibited more than 50% infection and were highly susceptible in their response against M. phaseolina
