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 the response of “Pandangwangi” to Xoo is still poorly understood. This paper reports the results of the evaluation of “Pandanwangi” response against BLB. This research was conducted in a greenhouse with artificial inoculation using Xoo strains III, IV, and VIII with bacterial suspension at 10 8 cfu.mL −1 . The results showed that the response of cv Pandanwangi to Xoo infection was different from the strain of Xoo . “Pandanwangi” cultivar was susceptible to Xoo strain III and VIII and very susceptible to strain IV.
