Allelism testing of miscellaneous stocks in Maize COOP phenotype only collection.

‑‑Stinard, PS

‑‑Jackson, JD

This report summarizes recent allele testing of miscellaneous stocks characterized by phenotype only in the Maize Genetics COOP Stock Center collection. Crosses were made between known heterozygotes where possible. Plants from the indeterminate1, lazy1, and ramosa crosses were scored in the field at maturity. Kernels were scored on the ear for the etched1 and viviparous crosses. Kernel samples from the etched1 crosses were planted in sand benches to confirm virescent phenotype. New designations have been assigned to these alleles. These stocks have been increased and placed on our stock list. It is expected that with further sorting and allelism testing of mutations characterized by phenotype only, additional alleles of characterized mutants will be discovered and placed in the main collection.

Data from the etched1 and viviparous crosses were compiled by Janet Day Jackson before her sudden and untimely death.
