Germination, moisture content, storage fungi, field fungi, internal damage, physical damage and 1000 seed weight of corn seed lots of 7 varieties were tested and path coefficient analysis was performed. The results showed that storage fungi and moisture content played important roles in affecting the seed germination. Both facters had strong negative effects, direct and indirect, on seed germination. The indirect effect of moisture content, through its influence on the development of storage fungi, was bigger than the direct effect. Field fungi, physical damage, internal damage and 1000 seed weight were not as important as storage fungi and moisture content in terms of affecting germination ability.
