Ginger (Zingiber officinale Rosc.) is an important member of the family Zingiberaceae due to its medicinal and seasoning properties. The study was conducted at Farawocha Research Center, during main cropping season three year 2009 to 2012 to find out the resistance accession of ginger bacterial wilt disease Ralstonia solanacearum biovar III race 4. The land was medium high and the soil was clay loam in texture. The experiment was laid out in Randomized Complete Block Design with three replications. A total of twenty four ginger accessions (24) different germplasm collected variety (Gm-41/08,Gi-190/73, Gi-52/68, GW-12/08, Gi-53/86, Gi-107/94, Gi-30/79, Gi-36/79, GN-305/73, Gi-75/20 and Gi-84/20) are more susceptible variety GN-181/08,G-102/78,G-57/86, and local Gi-(Basketo 01) as check were used in this experiment. Among these varieties, six verities including “Gi-180/73”, “Gi-37/79”, "Gi-30/73”, “GW-28/08”, “Gi-85/86” and “GH-06/95 (Basketo local)” was found to be moderately resistant against bacterial wilt having laid on percentage of disease incidence 28.87% to 37.5% in 2009 to 2010 E.C and four ginger cultivars “Gi-305/73” (48.6%),"Gi-38/79(Volvo)”,(47.5%)"Gi-70/79”(42.2%), Gi-190/73(40.6%) was found to be very high promised resistant bacterial wilt, having less disease incidence consecutively for three years. No resistant varieties/accessions were found in this investigation in both the year. Accession was have the same result, the highest yield (7.15 t/ha) was obtained from Gi- 305/73, Gi- 38/79 (Volbo), and Gi- 180/79 in 2009 to 2012EC while it was highest from Gi-Basketo 01 (7.27 t/ha) which was identical to GW-190/73, (7.02 t/ha) and Gi-181/86), (6.94 t/ha).
