Plant Disease Reporter v. 43, no. 10, p. 1124-1129Summary: Isolates of Diplodia maydis and certain corn single crosses
were exchanged between Minnesota, Missouri, and Oklahoma. The
corn entries were inoculated with each isolate in each of the three States
during 1954, 1955, and 1957. In general, the isolates of the fungus
were more pathogenic in States where they originated. All isolates
were more pathogenic in Missouri and Oklahoma than in Minnesota.
During 1955, when hot, dry weather prevailed in Minnesota, isolates
from Missouri and Oklahoma were more pathogenic in Minnesota
than was the isolate from Minnesota. The single crosses were
generally more resistant in Minnesota than in Missouri and Oklahoma, but resistance varied with fungus isolates, single crosses,
locations, year of the test, and with all of the interactions of the
major factors studied
