Abstract :
This study was performed to assess resistance potential of 142 indigenous accessions along with two check cultivars against bacterial leaf blight disease at the University of Agriculture, Peshawar-Pakistan during 2011 rice crop growing season. On artificial inoculation with Xanthomonas oryzae pv. Oryzae, the fundamental agent of bacterial leaf blight, most of the studied rice accessions and the two commercial rice cultivars displayed susceptible reactions. Seven rice accessions viz. UoA-2, UoA-5, UoA-11, UoA-48, UoA-53, UoA-102, and UoA-123 showed moderate levels of resistance while eleven rice accessions viz. UoA-4, UoA-6, UoA-22, UoA-41, UoA-60, UoA-67, UoA-68, UoA-84, UoA-126, UoA-129 and UoA-133 displayed strong resistance against the disease. The use of these resistant rice accessions are, therefore, recommended for deploying bacterial leaf blight resistant genes into commercial rice cultivars.
