Abstracts

Brown leaf spot disease is the most serious disease of rice. 25 varieties were screened against brown leaf spot caused by Helminthosporium oryzae during session (Kharif) 2014 and 2015. The results were four varieties recorded viz. NDR-359, CR-1, CR-2 and N-18 in highly resistant. Seven varieties were recorded viz. PR-103, IR-36, Prasd, Narendra-2, IR-597, OC-1339 and Cross-116 in resistant. Six varieties were recorded viz. IET-849, Pusa NR-381, Narendra-80, Narendra Dhan-97, Jalnidhi and Jallahari in moderately resistant. Three varieties were recorded viz. Rupali, MTU-7029 and Sweta in moderately susceptible. IET-2969 and Annapurna was recorded in susceptible. Three varieties were recorded viz. Nagina-22, CR-126 and Cauvery highly susceptible in all three screening conditions, i.e. laboratory, pot and field. In view of present investigation, it provides a useful information to the farmers by which they can use these varieties which are resistant to brown leaf spot disease of paddy. This may increase the productivity and save the economy of farmers.
