Bacterial Leaf Blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the limiting factors in rice production. A local cultivar rice “Pandanwangi” is a superior variety much preferred and cultivated by the farmers in Cianjur, West Java, Indonesia. The information about response of “Pandangwangi” to Xoo is still poorly understood. This paper reports the results of evaluation of “Pandanwangi” response against BLB. This research was carried out in greenhouse with artificial inoculation using Xoo strains III, IV, and VIII with bacterial suspension at 108 cfu.mL-1. The results showed that response of cv Pandanwangi  to Xoo infection was different between the strain of Xoo. “Pandanwangi” cultivar was susceptible to Xoo strain III and VIII and very susceptible to strain IV.
