| 0 | 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 |
| 1 | GSHO 209 | blx2.b | 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. Variation in color expression from dark to 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. Inheritance: Monofactorial recessive when complementary dominant alleles are present at the Blx1, Blx3, Blx4, and Blx5 loci. Located in chromosome 7HL [1L], approximately 9.9 cM distal from the nud (naked caryopsis) locus. Previous nomenclature and gene symbolization: Blue aleurone 1=Bl1 a second factor for blure aleurone. Non-blue aleurone 2=bl2. Mutational events: blx2.b in Nepal (CIho 595). Mutant used for description and seed stocks: blx2.b in Nepal (GSHO 209); also blx2.b in Bowman (PI 483237). | 1510682 | GSHO 209 |
| 2 | GSHO 234 | Pre2.a | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DONATED | 05/1994 | | | | | Genetic material | Purple or red coloration of the hull (chaff) and pericarp develops during the soft dough stage of grain fill, and fades as the grain matures. Anthocyanin pigments in an acid cell solution produce the red to violet color observed in the pericarp and lemma. Inheritance: Two dominant complementary genes (Pre1 and Pre2) control purple or red pigmentation of the lemma, palea, and pericarp. Located in chromosome 2HL, about 17.1 cM distal from the vrs1 (six-rowed spike 1) locus, and over 11.2 cM proximal fro the ant2 (anthocyanin-less2) locus. Previous nomenclature and gene symbolization: Purple chaff color=P. Purple chaff color=P1. Purple pericarp=P. Purple lemma =P. Red pericarp=R. Red pericarp 2=Re2. Mutational events: Pre2.a in Buckley (NSL 32606). Mutant used for description and seed stock: Pre2.a in Buckley 3277 (GSHO 234); Pre2.b from R.I. Wolfe's Multiple Dominant Marker Stock in Bowman (PI 483237)*9 (GSHO 1926). | 1510594 | GSHO 234 |
| 3 | 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 |
