Abstract

Sweet corn seed from several maize dwarf mosaic virus (MDMV)‐infected hybrids grown in the field were tested for transmission of MDMV through the seed. Seeds collected in 1979, 1980, 1981, and 1982, were germinated in the greenhouse the following winters. Only one seedling of 22,189 was MDMV‐infected During the last three years, seed were dissected at different maturities and the seed parts tested for the presence of MDMV by both infectivity and enzyme‐linked immunosorbent assay (ELISA). At 21 days after pollination, MDMV always was detected in the pericarp, but rarely in the endosperm or embryo. No MDMV was detected in the embryo of mature kernels, but virus occasionally was detected in the endosperm and pericarp. MDMV was regularly detected in unfertilized kernels and whole silks, but not in pollen by infectivity, ELISA or serological specific electron microscopy. MDMV was detected in glumes and whole anthers.
