Seed corn (Zea mays) produced in commercial nurseries in Hawaii was harvested from symptomatic plants naturally infected with maize chlorotic mottle virus (MCMV). In Nebraska greenhouse studies, the seeds were planted and 14-day-old seedlings were assayed for MCMV. Seed transmission was found by ELISA and confirmed by symptomatology and mechanical transmission in 17 of 42,000 plants from 25 seed lots submitted by three seed companies. Some of the factors relating to seed transmission were tested.
