| 0 | GSHO 29 | eog1.a | Hordeum vulgare L. subsp. vulgare | California, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | A multiple allelic series exists at this locus which controls increased size of the outer glumes (glumes) of the spikelet. Glume width varies from 2.5 to 4.0 mm depending on genetic background and specific allele. Glume awn length varies from awnless to nearly as long as the lemma awn (92 mm) depending on the eog allele present and genes at other loci, but some confusion has occurred regarding alleles at the eog locus and expression of other glume characteristics. The size of the glume may range from less than twice normal width in CIho 14955 to lemma-like glumes in Triple Bearded Mariout. Inheritance: Monofactorial recessive. Located in chromosome 2HL, about 30.5 cM proximal from the vrs1 (six-rowed spike 1) locus. Previous nomenclature and gene symboliation: Extended outer glumes=e. Wide glumes=w. Macrolepis=lep-e(lep-a). Long outer glume=log. Elongated outer glume=e.
