sh5 is allelic to bt1
--Philip Stinard

The two mutants sh5 and bt1 have similar phenotypes (shrunken/collapsed endosperms) and map to the same region of chromosome 5. To test the relationship between these two mutants, plants homozygous for sh5 were crossed to plants heterozygous for bt1. In all instances, the progeny segregated 1:1 for plump : shrunken kernels, indicating allelism of these two mutants. Since bt1 has precedence over sh5, the name bt1-sh5 is proposed for the sh5 allele.
