Abstract

The bean crop is exposed to many diseases that lead to significant losses, such as the bacterial wilt of common bean caused by Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff). Currently, the bacterial wilt of common bean has been a new problem for the bean crops in several Brazilian regions. The genetic resistance has been the most efficient approach for disease control; however, the possible existence of genetic variability in Cff isolates may be a harmful consequence to the plant improvement especially in relation to the resistance stability and durability. The purpose of this work is evaluation the molecular and pathogenic variability of Curtobacterium flaccumfaciens pv. flaccumfaciens isolates from bean (Phaseolus vulgaris L.) (AU)
