Virulence of Phoma lingam to cabbage

1980

Bonman, J.M. | Gabrielson, R.L. | Williams, P.H. | Delwiche, P.A.

Isolates of Phoma lingam with varying degrees of virulence were differentiated by symptoms on wound-inoculated cabbage cotyledons and pigment production in vitro. Isolates that produced pigment caused only cotyledonary tissue darkening and limited tissue collapse, did not spread significantly in seed beds, and produced only superficial lesions on transplanted cabbage. Isolates that did not produce pigment caused cotyledonary tissue collapse and were able to spread in cabbage seed beds and damage transplanted cabbage grown to maturity. Within the later isolates, a range of field virulence was observed.
