| 0 | GSHO 2506 | blx3.c | Hordeum vulgare L. subsp. vulgare | Idaho, United States | | | Historic | 1996 | DEVELOPED | | | | | | Genetic material | Blue aleurone color is due to anthocyanin pigments which occur as lumps inside many aleurone granules in some or all aleurone cells. Variation in color expression from dark blue to an off-whit is caused by environmental factors and modifying genes. Aleurone color is best observed in well filled grain that is magnified to show individual aleurone cells, after more superficial tissues have been peeled off. Inheritance: Monofactorial recessive when complementary dominant alleles are present at the Blx1, Blx2, Blx4, and Blx5 loci. Located in chromosome 4HL, close to the blx1 (non-blue aleurone xenia 1) locus, and over 25.3 cM distal from the Kap (hooded lemma) locus. Previous nomenclature and gene symbolization: Non-blue aleurone 3=bl3. Complementary factors for blue vs white aleurone=Bly and bly. Mutational events: blx3.c in line Blx selected from Composite Cross V. Mutant used for description and seed stocks: blx3.c in line Blx selected from Composite Cross V. | 1545118 | GSHO 2506 |
| 1 | GSHO 2507 | blx4.d | Hordeum vulgare L. subsp. vulgare | North Dakota, United States | NSGC |  | | 1996 | DONATED | 04/1996 | | | | | Genetic material | Blue or pink aleurone color is due to anthocyanin pigments which occur as lumps inside many aleurone granules in some or all aleurone cells. Variation in color expression from pink to an off-white is caused by environmental factors and modifying genes. The pink and red color aleurone colors are easier to observe in well filled grain that is magnified to show individual aleurone cells, after more superficial tissues have been peeled off. A brick red aleurone color results from the interaction of the ibl (intense blue aleurone) gene with the blx4.d gene in homozyotes. Inheritance: Monofactorial recessive when complementary dominant alleles are present at the Blx1, Blx2, Blx3, and Blx5 loci. Located in chromosome 4HL, very close to the blx1 (non-blue aleurone xenia 1) locus, and over 29.5 cM distal from the Kap (hooded lemma) locus. Previous nomenclature and gene symbolization: Non-blue (pink) aleurone 4=bl4. Mutational events: blx4.d plus ibl in Ethiopian 637; blx4.d only in Ab 6, EP79, Grannenlose Zweizeilige. Mutant used for description and seed stocks: blx4.d in Ab 6 (PI ??). | 1545102 | GSHO 2507 |

Inheritance: Monofactorial recessive when complementary dominant alleles are present at the Blx1, Blx2, Blx3, and Blx4 loci. Located in chromosome 7HL [1L], associated with the red stem trait controlled by the dominant allele at the ant1 (anthocyanin-less 1) locus; linked to the blx2 (non-blue aleurone xenia 2) locus, but not to the fch12 (chlorina seedling 12) locus.
