Abstract

Corn stocks showing virus-induced aberrant ratio (AR) at the “A” locus were found to have recessive alleles at the R and/or C loci. Since by the known pedigree these loci should be homozygous dominant, the results suggest an inactivation of maize genes by a mechanism as yet unknown. The presence of recessive alleles at these additional loci can explain the segregation ratios obtained in these particular stocks.
