Stalk-rot reactions of 99 corn inbreds inoculated with Colletotrichum graminicola or Diplodia maydis were not closely correlated. Because of this, selection for stalk-rot resistance on the basis of reactions to D. maydis alone may no longer be suitable in areas where C. graminicola is potentially damaging. Methods of inoculation and reactions of some widely-used inbreds to the two pathogens are presented.
