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

This report summarizes allele testing of lazy 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 la* and plants homozygous for la1. Plants were scored at maturity in both Illinois and Puerto Rico. 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 lazy mutants will be discovered and allele tested.
