| 0 | GSHO 132 | Pvc1.a | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DONATED | 05/1994 | | | | | Genetic material | Purple pigment is produced by the presence of anthocyanins. When Pvc is expressed, purple pigmentation of the kernel is confined mainly to the lemma veins. The pigments are formed late during grain fill when the lemma is exposed to sunlight, and they tend to fade as the spike matures. Inheritance: Monofactorial dominant, but Buckley suggested that three pairs of genes controlled expression of purple pigmentation of lemma veins. Located in chromosome 2HL, about 22.2 cM distal from the vrs1 (six-rowed spike 1) locus. Previous nomenclature and gene symbolization: Purple veined lemma=C. Purple veined lemma=Pc. Mutational events: Pvc1.a in Buckley 2223-6. Mutant used for description and seed stocks: Pvc1.a in Buckley 2223-6 (GSHO 132); Pvc1.a from R.I. Wolfe's Multiple Dominant Stock in Bowman (PI 483237)*7 (GSHO 1929). | 1510814 | GSHO 132 |
| 1 | GSHO 185 | blx1.a | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DONATED | 05/1994 | | | | | Genetic material | Blue aleurone color is due to anthocyanin pigments which occur as lumps inside many aleurone granules in some or all aleurone cells. Variaiton in color expression from dark blue to an off-white 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. In heritance: Monofactorial recessive when complementary dominant alleles are present at the Blx2, Blx3, Blx4, and Blx5 loci. Located in chromosome 4HL, over 13.6 cM distal from the glf3 (glossy leaf 3) locus. Previous nomenclature and gene symbolization: Blue aleurone=Bl. Complementary factors for blue vs white aleurone=Bl1 and bl1. Complementary factors for blue vs white aleurone=Blx and blx. Mutational events: blx1.a in Goldfoil (CIho 1866). Mutant used for description and seed stocks: blx1.a in Goldfoil (GSHO 185). | 1510621 | GSHO 185 |
| 2 | GSHO 707 | rob1.a | Hordeum vulgare L. subsp. vulgare | California, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | The lemma, palea, and rachis have an orange pigmentation that is present in immature spikes, can be observed at heading, and is retained in mature grain and spikes. The orange pigmentation is visible at the base of sheath of seedlings and in exposed nodes after jointing. Internodes have a layer of orange tissue and stems have an orange color as the straw dries. The mutant stock for rob1.f (OUM189) has a lighter orange lemma color than that in other mutants at the rob locus. Inheritance: Monofactorial recessive. Located in chromosome 6HS, about 10.8 cM proximal from the msg36 (male sterile genetic 36) locus, and about 2.2 cM distal from the cul2 (uniculm 2) locus. Previous nomenclature and gene symbolization: Orange lemma=pl. Orange lemma=br. Orange lemma=o. Robiginosum-o=rob-o. Mutational events: rob1.a in CIho 5649 (GBC340); rob1.b (OUM185), rob1.c (OUM186), rob1.d (OUM187), rob1.e (OUM188), rob1.f (OUM189) in Akashinriki (OUJ659, PI 467400); rob1.1, rob1.2 in Bonus (PI 189763), rob1.3, rob1.4, rob1.5 in Foma (CIho 11333), rob1.6 in Kristina. Mutant used for description and seed stocks: rob1.a in CIho 5649 (GSHO 707); rob1.a in Bowman (PI 483237)*7 (GSHO 2069). | 1513863 | GSHO 707 |
