Abstract
Biodiversity among 25 strains of Xilnthomonas campestris pv cirri isolated from different localities of Pakistan was distinguished through Immunodiffusion tests. Two serovars were detected based on the presence of a sharp band or faint band in gel diffusion plates. Antisera XC.91 and XC-93 formed a very strong precipitin band with strain XC-58, XC-91, XC-93, XC-lOO, XC-1O1, XC-105, XC-107, XC-114 and XC-125 with a faint band with XC-92, XC-94, XC95, XC-96, XC-1O2, XC-103, XC-1O6, XC-1O9, XC-11O, XCIll, XC-I13, XC-115 and XC-12l. Three strains viz., XC-97, XC-98 and XC-99 did not give any reaction against either of the two antisera and thus appeared to be non specific.
