Silage productivity and resistance to rice black streaked dwarf virus (RSDV) of six Korean-improved and six US introduced corn genotypes were tested in the southern part of Korea. There was a negative correlation between culm length retarded by RBSDV and coefficients of variance of culm length. Frequency distribution of culm length could be classified as there genotypic groups according to the type of distribution and percentage of RBSDV diseased plants. There were negative correlations between percent RBSDV diseased plants at harvest and culm length, percent ear bearing plants, silage yield, or ear yield but percent RBSDV diseased plants did not relate to the ear/silage ratio and stover yield. Silage yield of Pioneer XCF38 was highest, but that of Suwon 89 and NC 6131 was lowest
