This report summarizes allele testing of stocks of zebra necrotic
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. In most cases
crosses were made between known heterozygotes and homozygous zn2
plants. Plants were scored at the seedling stage and again at maturity.
Proposed new designations have been assigned to these alleles. These stocks
have been increased and placed on the 1999 stocklist. During the screening
of green stripe mutants, one culture was observed to have more of a zebra
necrotic phenotype and upon testing was determined to be allelic to zn2.
It is expected that with further sorting of mutations characterized by
phenotype only, additional zebra necrotic mutants will be discovered and
