| 0 | GSHO 1065 | als1.a | Hordeum vulgare L. subsp. vulgare | Ontario, Canada | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Lateral spikelets at the base of the spike fail to develop or are partially developed. Tillers are large, coarse, and stiff, and only 1 or 2 tillers are produced in the six-rowed stock. The plant resembles the uniculm mutant. Plants of the Bowman backcross-derived line commonly produce 3 to 5 tillers. Inheritance: Monofactorial recessive. Located in chromosome 3HL, about 31.2 cM distal from the uzu (uzu) locus, and about 39.7 cM proximal from the cur2 (curly 2) locus. Previous nomenclature and gene symbolization: None. Mutational events: als1.a in Montcalm (Alb Acc 281). Mutant used for description and seed stocks: als1.a in Montcalm (GSHO 1065); als1.a in Bowman (PI 483237)*7 (GSHO 1990). | 1513839 | GSHO 1065 |
| 1 | GSHO 107 | fch2.c | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DONATED | 05/1994 | | | | | Genetic material | Seedlings have a pale yellow-green color, which persists until near maturity under greenhouse or field conditions. Development of homozygous is delayed, but the stunted plants survive to produce seed. A complete absence or greatly reduced levels of chlorophyll b were found in mutant plants. Respiratory and photosynthetic rates of detached leaves and intact plants were not significantly different from those of normal plants. However, the growth rate of mutant plants decreased after the endosperm was depleted. An absence of chlorophyll b-binding proteins in the photosynthetic membranes was found in fch2 mutants. Inheritance: Monofactorial recessive. Located in chromosome 3HL, about 7.7 cM distal from the cur2 (curly 2) locus. Previous nomenclature and gene symbolization: Chlorina seedling 2=f2. Light green 5=lg5. Chlorina seedling f2=clo-f2. Mutational events: fch2.c in 28-3398 Chlorina; fch2.y (lg5) in CIho 6151; clo-f2.2800, -f2.2807, -f2.3613 in Donaria (PI 209784), -f2.101, -f2.102, -f2.103, -f2.105, -f2.107, -f2.108, -f2.109 in Tron, -f2.122, -f2.123, -f2.133 in Bonus (PI 189763). Mutant used for description and seed stocks: fch2.c in 28-3398 (GSHO 107); fch2.c in Bowman (PI 483237)*7 (GSHO 1993). | 1510706 | GSHO 107 |
| 2 | GSHO 1140 | yst1.a | Hordeum vulgare L. subsp. vulgare | Ontario, Canada | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Longitudinal yellow stripes appear on seedling leaves and persist until the preripening stage. In some crosses and under certain environmental conditions, the most heavily striped F2 plants fail to reach maturity. There is no evidence for a cytoplasmic association in the inheritance patterns. Expression of the yst1.a allele in the Bowman backcross-derived line is reduced to very narrow streaks that occur infrequently. Inheritance: Monofactorial recessive. Located in chromosome 3HS, about 2.9 cM proximal from the zeb1 (zebra stripe 1) locus, and about 7.6 cM proximal from the uzu (uzu) locus. Previous nomenclature and gene symbolization: Yellow stripe=ys. Yellow streak=yst. Mutational events: yst1.a in Gateway. Mutant used for description and seed stocks: yst1.a in Gateway (GSHO 1140); yst1.a in Bowman (PI 483237)*7 (GSHO 1959). | 1514332 | GSHO 1140 |
| 3 | GSHO 1279 | zeb1.a | Hordeum vulgare L. subsp. vulgare | Minnesota, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Seedlings may have pale green to yellow bands across the leaves when germinated under cold conditions in the field. Cold room studies showed that development of a mutant phenotype in seedlings could be induced by 10 to 15 days of cold treatment (0 to 1 C) if initiated within one day after wetting of the seed. Alternating cold and warm temperatures in the field induced diagnostic symptoms. Inheritance: Monofactorial recessive. Located in chromosome 3HL, about 7.0 cM proximal from the uzu (uzu) locus. Previous nomenclature and gene symbolization: Zebra stripe=zb. Mutational events: zeb1.a in Mars (C3-1). Mutant used for description and seed stocks: zeb1.a in Mars (GSHO 1279); zeb1.a in Bowman (PI 483237)*3 (GSHO 1964). | 1513696 | GSHO 1279 |
| 4 | GSHO 568 | wst4.d | Hordeum vulgare L. subsp. vulgare | Japan | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Mutants grown at low temperatures exhibit numerous, wide, chlorotic (white) streaks on developing leaves. If termperatures are continuously low, plants appear highly chlorotic. As termperature rises, the white streaks gradually disappear. Exposure to 3 degrees Celius for two weeks after sowing is sufficient to induce distinct streaks in the first and second leaves. Inheritance: Monofactorial recessive. Located in chromosome 2HL, about 6.5 cM distal from the eog (elongation outer glume) locus. Previous nomenclature and gene symbolization: None. Mutational events: wst4.d in Kanyo 7 (OUL068). Mutant used for description and seed stocks: wst4.d in Kanyo (GSHO 568); wst4.d in Bowman (PI 483237)*4(GSHO 1905). | 1512373 | GSHO 568 |
| 5 | GSHO 681 | lgn4.d | Hordeum vulgare L. subsp. vulgare | Minnesota, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Seedlings are light green in color, and the light green color persists until near maturity. In the Bowman backcross-derived lines, the plants are weaker than normal sibs and produce thinner seeds. Inheritance: Monofactorial recessive. Located in chromosome 4HL, about 5.0 cM distal from the Kap (hooded lemma) locus and about 4.0 cM proximal from the glf1 (glossy leaf 1) locus. Previous nomenclature and gene symbolization: Light green 1=lg1. Light green 4=lg4. Light green 9=lg9. Mutational events: lgn4.d (lg1) in Himalaya X Ingrescens; lgn4.i (lg9) in No 156, an unknown cultivar (GSHO 1, GSHO 94).
