| 0 | GSHO 216 | rtt1.a | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Spikes are highly modified with numerous immature spikelets and complete sterility. The arrangement of bracts in the spikelets suggests that they contain numerous florets. Because the homozygous recessive is completely sterile, the stock must be maintained in the heterozygous condition. A semidominant interaction between rtt1.a and the Rtt1.b (normal) allele in Okaiku 3 was reported by Takahashi et al. Inheritance: Monofactorial recessive. Located in chromosome 2HS, about 6.0 cM distal from the fch15 (chlorina seedling 15) locus. Previous nomenclature and gene symbolization: Rattail spike=rt. Mutational events: rtt1.a in Goldfoil, Rtt1.b in Okaiku 3 (OUL011). Mutant used for description and seed stocks: rtt1.a in Goldfoil (GSHO 216). | 1510821 | GSHO 216 |
| 1 | GSHO 49 | fch15.x | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | The normal color of seedlings is altered to "apricot yellow" when plants are grown in the field under low temperature. Plants respond to higher temperatures and may be grown to maturity in suitable environments. The yellow plant color is stable neartly to maturity. Inheritance: Monofactorial recessive. Located in chromosome 2HS, about 18.5 cM distal from the fch1 (chlorina seedling 1) locus. Previous nomenclature and gene symbolization: Orange seedling=or. Mutantional events: fch15.x or or1.a in Trebi. Mutant used for description and seed stocks: fch15.x in Trebi (GSHO 49). | 1510650 | GSHO 49 |
| 2 | GSHO 61 | abo8.h | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Seedlings are white in color and devoid of normal pigments. Later, plants with this phenotype were classified as albino mutants. The abo8.h gene must be maintatined as a heterozygous stock. Inheritance: Monofactorial recessive. Located in chromosome 7HS[1S], about 27.2 cM distal from the nud (naked caryopsis) locus, over 11.3 cM distal from the nud locus, and about 18.0 cM distal from the fch8 (chlorina seedling 8) locus. Previous nomenclature and gene symbolization: White seedling c2=ac2. Albino seedling c2=ac2. Albino seedling-m=alb-m. Mutational events: abo8.h in Coast (Coast II); alb-m.27 in Bonus (PI 539132). Mutant used for description and seed stocks: abo8.h in Coast (GSHO 61). | 1510684 | GSHO 61 |
| 3 | GSHO 70 | abo2.b | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DONATED | 05/1994 | | | | | Genetic material | Seedlings lack normal pigmentation; they are white and die at a two or three leaf stage. Robertson suggested that an albino 3 stock [abo4 9a30] may have been used in his linkage studies instead of albino 1 (a1). The abo2.b gene must be maintained as a heterozygous stock. Inheritance: Monofactorial recessive. Located in chromosome 2HS, about 13.0 cM distal from the fch1 (chlorina seedling 1) locus, about 5.5 cM proximal from the fch15 (chlorina seedling 15) locus, and over 9.4 cM distal from the msg2 (male sterile genetic 2) locus. Previous nomenclature and gene symbolization: Albino 1=a1. Albino seedling 2=a2. Mutational events abo2.b in Nilsson-Ehle No 2. Mutant used for description and seed stocks: abo2.b in Nilsson-Ehle No 2 (GSHO 70). | 1510824 | GSHO 70 |
