Allelism testing of unplaced golden stocks in Maize COOP's collection
--Jackson, JD

This report summarizes allele testing of stocks of unplaced golden mutations in the Maize COOP's stock collection. Some of these unplaced mutations have been found in other COOP stocks and some have been sent in by cooperators over the years. Crosses were made between homozygotes or known heterozygotes. In most cases plants were scored at the seedling stage as well as at maturity. Proposed new designations have been assigned to these alleles. These stocks have been increased and placed on the 1996 stocklist. During the screening of unplaced pale-green mutants, one culture was observed to have more of a golden phenotype and upon testing was determined to be allelic to g2. It is expected that with further sorting of unplaced mutations in the COOP's collection additional golden phenotypes will be discovered and allele tested.
