Abstract: Blast disease is one of the major disease of rice causing substantial yield losses. Host plant resistance is the best means of combating the blast disease in rice. The aim of the present investigation was to identify the superior hybrids and their parents with blast resistance by adopting Uniform Blast Nursery (UBN) at Rice Research Center, ARI, Rajendranagar during Rabi, 2017-18. The experiment was carried out with 12 parents, 32 hybrids along with susceptible check (TN1). The disease scoring was done by using 0-9 scale of Standard Evaluation System (SES) developed by IRRI, 2013. Accordingly based on the disease scoring, the genotypes were categorized as resistant, moderately resistant/ susceptible and susceptible types.
