The present study was conducted at the University of Agriculture Peshawar, in the rice growing season of the year 2012 to investigate the genetic potential against bacterial leaf blight and to study yield potential of indigenous rice germplasm under natural condition. Twenty three indigenous rice germplasm and two commercial varieties i.e. Kashmir Basmati and IR-8 were studied. Bacterial suspension of concentration 108 CFU/ml was prepared from mixture of Xanthomonas oryzae pv. oryzae. Clip method of artificial inoculation was used. Out of all the tested genotypes thirteen were moderately resistant, five were moderately susceptible, six were susceptible and Kashmir Basmati showed highly susceptible response. None of the genotype was resistant to bacterial leaf blight. Among the tested genotypes Acc. 6505, 6508, 6509, 6515 6535 performed well for quantitative yield parameters along with moderately resistance response to BLB. Being highly susceptible variety Kashmir Basmati still showed good result for grain yield (0.78 kg/plot) relative to others.
