Sclerotinia rot incited by Sclerotinia sclerotiorum is very serious disease of rapeseed- mustard throughout world. For over two decades, research on the management of this disease has been directed at various approaches, and yet currently available methods have not provided effective control. Therefore, different rapeseed-mustard genotypes of diverse origin (indigenous and exotic origin) were screened for their relative resistance/tolerance to Sclerotinia rot disease under permanent sick plot conditions in field at Research Area of Oilseeds Section, Department of Genetics and Plant Breeding, CCS HAU, Hisar during rabi 2012-13 and 2013-2014. Out of sixty nine genotypes, none of the genotypes was found resistant (<10% D.I.), however, nine genotypes viz., Varuna albino, Montara, Ringot 1, Brassica I, Brassica II, EC 126745, EC 322090, EC 322091, Kiran showed moderately resistant reaction (10-20 % D.I.) against Sclerotinia rot disease. These sources of moderate resistant genotypes need to be tested for their resistance with other inoculation techniques and after that may be utilized in resistance breeding programme for at least development of tolerant variety of rapeseed-mustard.
