Maize dwarf mosaic virus: Symptomatology and yield reactions of susceptible and resistant sweet corns
Environmental Entomology 13 (1), 318-323
Abstract: Numerous sweet corn genotypes and cultivars were evaluated for field resistance to aphid-borne maize dwarf mosaic virus infection. The entries displayed wide ranges in symptomatology and yield reactions to severe MDMV infection pressure. Plant barrenness contributed greatly to yield reductions in all trials. The percent infected plants at 45 days postplant was not significantly correlated with yield in two of the three trials. It was shown that poor yield performance of a genotype for the fresh market may not eliminate it as a useful processing sweet corn. The data show evident progress in the development of MDMV resistance in sweet corn, but high ear quality is lacking.
