Abstract:
Inbred lines of Zea mays with different cytoplasms were inoculated with race T,C,O of B.maydis,and the reactions and toxin yields of each race and their colony growing speeds, spore forms, germinant types and speeds,and amounts of spores per area were studied. The results showed that C cytoplasm to race C and T cytoplasm to race T were more sensitive than other cytoplasms, toxin amounts produced by race T and race C were much more than that of race O,and other biological traits were also different significantly.
Key words:
Bipolarisr maydis,
Physiological race,
Inbred lines of Zeamays with different cytoplasm
