Allelism testing of green stripe stocks in Maize COOP Stock Center collection
--Jackson, JD

This report summarizes allele testing of green stripe mutations characterized by phenotype only in the Maize COOP Stock Center collection. Some of these mutations have been found in other COOP stocks and some have been sent in by cooperators over the years. Crosses were made between plants known to be heterozygous for the gs* and plants homozygous for gs1 or gs2. In most cases plants were scored at the seedling stage and again at maturity. Proposed new designations have been assigned to those alleles for which positive results were obtained. These stocks have been increased and placed on the 1999 stocklist. It is expected that with further sorting of mutations characterized by phenotype only, additional green stripe mutants will be discovered and allele tested.
