This study was initiated to determine the chromosomal location of the grandpa (gp) gene within the barley genome. The gp gene was placed on the long arm of chromosome 2 as indicated by linkage association with liguleless (li).Tests of allelism showed the gp gene to the allelic with the gp-2 gene. Seven sources of "yellow" chlorophyll mutants when crossed to grandpa plants gave albino double recessive seedlings. Three other sources of "yellow" chlorophyll mutants in the double recessive combination with grandpa exhibited yellow and white bands on the leaves. Double recessive individuals carrying the mottled (mt2) and grandpa genes were also albino. This is evidence of gene interactions between chlorophyll mutant genes.

ABSTRACT An association was found earlier between the Ep1 gene locus coding for an endopeptidase and the endosperm color gene Y1 on chromosome 6 of Zea mays. By employing primary trisomics we have unequivocally placed the Ep1 gene on chromosome 6, closely linked to the Y1 locus. Additionally we describe new alleles at the Ep1 locus, and present evidence for the existence of a second endopeptidase system in maize.
