Allele test results for Maize Genetics Stock Center �phenotype only� stocks.

--Stinard, PS

We report here the results of tests of allelism of white endosperm/green seedling and white endosperm/viviparous mutants from the Maize Genetic Stock Center�s collection of mutants characterized by phenotype only. In the case of the new y1 alleles, homozygous mutant plants were crossed by homozygous y1 testers; allele tests were considered positive if the resulting ears bore white kernels. In the case of the new w3 allele, heterozygous mutant plants were crossed by heterozygous w3 testers and kernels from the resulting ears were seedling tested for the albino seedling w3 phenotype. The mutants which gave positive tests of allelism are presented in Table 1.
