Overview on pathogen diversity in the bacterial diseases populations of common bean (Phaseolus vulgaris L.) in Bulgaria

Ivan Kiryakov

Abstract: Common and halo bacterial blights are the key diseases of common bean (Phaseolus vulgaris L.) in Bulgaria. Under favorable weather condition these diseases causes over 40% losses of yield and quality of susceptible varieties. The use of resistant varieties is considered to be the most efficacy and cost-effective measure to control the bacterial diseases. Effectiveness of breeding programs for resistance is closely related to the research of virulent and aggressive diversity in pathogen populations. Systematized information on the pathogenic diversity in the populations of the common and halo bacterial blights in Bulgaria in the last 40 years is presented. It is consistent with the changes in pathogen taxonomy, as well as with strain and race diversity in various regions of the world, including Bulgaria.
