Abstract: Rice (Oryza sativa L.) is a staple food in many countries and food security to millions of population in the world and is one of the major food crops of India. Stem rot is the one among major diseases of paddy infect the crop from moderate to severe form and also result in commercial yield losses. Looking to the disease severity, the present investigation was carried out to study the sources of resistance of pathogen in order to minimize the crop losses of rice. Screening of forty four genotypes along with two susceptible checks against stem rot pathogen under artificial inoculation condition during kharif 2019 revealed that, 18 genotypes were found moderately resistant viz., NVSR-317, NVSR-348, NVSR-355, NVSR-2147, NVSR-2566, NVSR-330, NVSR-360, NVSR-365, NVSR-370, NVSR-374, NVSR-405, NVSR-407, NVSR-2102, NVSR-2117, NVSR-2130, NVSR-2140, NVSR-2153 and IET-24336. Whereas, 12 genotypes viz., NVSR-2101, NVSR-328, NVSR-2528, NVSR-331, NVSR-335, NVSR-364, NVSR-384, NVSR-2435, NVSR-368, IET-25470, GR-11 and TN-1 were found susceptible to Sclerotium oryzae.
