Mutable viviparous kernels were uncovered in the progeny of a self-pollinated ear in a colored line that was derived from a population that had mutator activity. The mutant was identified as being an allele of vp1 and was designated vp-m451 (Scheffler and Peterson MNL 58:5). Mutability of this allele is under the control of the independent element Cy (Schnable and Peterson MNL 58:9) and thus designated vp-rcy.
The relation of vp-m451 to Cy is illustrated below, where receptor alleles of known transposable element systems were tested with the regulatory element responsible for the viviparous mutability.
