The relative pathogenicity of isolates of Macrophomina phaseolina was
comparable both on sunflower tissue cultures and on mature plants and
seedlings. The relative susceptibility of the different sunflower line
s in vitro showed a similar pattern for cotyledon callus cultures, but
not for immature embryo cultures. Although these protocols appear to
be unsuitable for the selection of novel disease resistance, they do o
ffer the potential for a rapid, non-destructive screen for resistant m
aterial.
