The 60 F1s (derived by line x tester analysis) along with their twenty three parents and two check varieties (Narendra Usar dhan 3 and IR 28) were tested against the Bacteria leaf blight, under sodic soil during Kharif, 2015 at the Research Farm of the Department of Genetics and Plant Breeding, Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Faizabad (U. P.). The experiment was conducted in sodic soil at pH =9.2, EC =2.21dSm-1 and ESP 45%. Resistance against Blast was assessed based on the damaged leaves following 0-9 scale as per the SES, IRRI, Manila, Philippines. Four crosses and one parent were found immune. Six parents, twenty two crosses and one check (Narendra Usar 3) were resistant and recorded damage score of ‘1’ indicating resistance to BLB. Eighteen parents, twenty nine crosses and one check (IR 28) were moderately resistant and only three crosses (IR 13 T146 x Narendra 5026, A69-1 x Sarjoo52, NDRK 50036 x Sarjoo52,) were found to be moderately susceptible to BLB damage. The genotypes which were highly resistant may be used as donors in resistant breeding programmes against Xanthomonas oryzae pv. oryzae,
