Abstract
Abstract
Xanthomonas campestris pv. oryzae is an important and destructive pathogen causing bacterial leaf blight disease in rice plant. The different tests were conducted in this research work to know the biochemical properties of the pathogen by the three rice isolates KRH-2, Swarna & Jurly and also investigation of resistant variety of rice germplasm. Pathogen was subjected to various biochemical tests, the results indicated that H2S (hydrogen sulphide) production test +ve in cysteine & -ve in peptone, Starch hydrolysis in KRH-2 & Swarna rice isolates showed +ve reaction whereas, negative results were obtained for Starch hydrolysis in Jurly rice isolate, Fluorescent test and Gram staining showed negative reaction whereas, positive reaction were observed in Catalase test, Liquefaction of Gelatin, KOH Solubility test, Protein digestion test.
