Stem rot of corn is worldwide disease. Incidence of the disease is generally about 10% and sometimes gets up to above 30 % in serious regions. Stem rot of corn is tending to increase recent years in Heilongjiang province. This study was conducted from 1989 to 1992. One hundred and thirty eight developed "Long Kang series"of inbreed lines and 89 introduced stable inbreed lines were inoculated by cutting roots in the soil and 19 susceptible lines and 17 high level resistant lines were screened. The resistant level in F_1 was between its parents and inclined to female parent.
