Using Robertson's Mutator, a large number of recessive defective-kernel mutants have been produced for the purpose of transposon tagging. As part of their genetic characterization, we have allele-tested many of the mutants with each other and with previously described dek mutants (Neuffer and Sheridan, Genetics 95:929, 1980). Tests were conducted on the basis of similarity of phenotype and/or assignment to chromosome arm. Table 1 shows Mu-induced defective kernel mutants that were found to be allelic to previously described mutants and/or to each other.
