Plants are 3/4 normal height, maturity is delayed, and seedlings are very responsive to gibberellic acid. In the Bowman backcross-derived line, leaves are wider and shorter than in the recurrent parent. Inheritance: Monofactorial recessive. Located in chromosome 3HS, over 16.3 cM distal from the alm (albino lemma) locus. Previous nomenclature and gene symbolization: Dwarf 4=dw4. Mutational events: lzd1.a in Akashinriki (OUM005).

| 1 | GSHO 2488 | sld1.a | Hordeum vulgare L. subsp. vulgare | Japan | NSGC |  | | 1996 | DEVELOPED | | | | | | Genetic material | Plant height is reduced to about 1/2 to 2/3 of normal, plant development is delayed, and plants are slightly yellow green in color. The normal distribution of leaves is altered because the peduncle is relatively long in proportion to the other i internodes. Plants homozygous for the sld1.c allele are slightly weaker and shorter than sld1.a plants in their respective Bowman backcross-derived lines. Inheritance: Monofactorial recessive. Located in chromosome 3HL, over 6.3 cM distal from the uzu (uzu) locus, and about 20.5 cM distal from the uzu locus. Previous nomenclature and gene symbolization: Dwarf 1=dw1. Light green dwarf=dw-1. Mutational events: sld1.a in Akashinriki (OUM148); sld1.c (862PK, GSHO 2489) in Plena (PI 321822). Mutant used for description and seed stocks: sld1.a in Akashinriki (GSHO 2488); sld1.a in Bowman (PI 483237)*7 (GSHO 1970); sld1.c in Bowman*7 (GSHO 1972). | 1545058 | GSHO 2488 |
| 2 | GSHO 2499 | wnd1.a | Hordeum vulgare L. subsp. vulgare | Japan | NSGC |  | Not Available | 1996 | DEVELOPED | | | | | | Genetic material | Plants are semidwarf (15 cm shorter than the original cultivar) and have a pronounced coiling or winding of the upper portion of peduncle. In the Bowman backcross-derived line, which lacks the gene for dense spike (dsp1.a), very little reduction in plant height is observed. However, plants have a distinct coiling of the upper portion of the peduncle. Inheritance: Monofactorial recessive. Located in chromosome 7HS [1S], over 25.4 cM distal from the dsp1 (desnse spike 1) locus. Previous nomenclature and gene symbolization: None. Mutational events: wnd1.a in Kogen-mugi (G754). Mutant used for description and seed stocks: wnd1.a in Kogen-mugi (OUM309, GSHO 2499); wnd1.a in Bowman (PI 483237)*7 (GSHO 1832). | 1545055 | GSHO 2499 |
| 3 | 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).

The naked caryopsis trait is expressed in all environments. Inheritance: Monofactorial recessive. Located in chromosome 7HL{1L]; near the centromere, about 9.6 cM proximal from the lks2 (short awn 2) locus, and about 10.5 cM proximal from the dsp1 (dense spike 1) locus. Previous nomenclature and gene symbolization: Naked caryopsis=k. Naked caryopsis=s. Naked caryopsis=n. Hulless=h. Mutational events: nud1.a in Himalaya (CIho 1312); nud1.b in Haisa (Mut 4129), nud1.c (Mut 3041/62) in Ackermann's Donaria (PI 161974).

| 5 | GSHO 1232 | dsp1.a | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DONATED | 05/1994 | | | | | Genetic material | Spike length is reduced because rachis internode length is reduced to about 2/3 normal. The reduction in rachis internode length caused by the dsp1.a and uzu1.a (uzu) alleles is similar and additive. In F2 progenies, the dsp1.a gene has pleiotropic effects on coleoptile length, culm length, and grain size. Inheritance: Monofactorial recessive. Located in chromosome 7HS [1S], about 10.5 cM distal from the nud (naked caryopsis) locus. Previous nomenclature and gene symbolization: Dense spike=l. Lax spike=L1. Short spike=e. Mutational events: dsp1.a in many cultivars of Oriental origin, often associated with the short awn gene. Mutant used for description and seed stocks: dsp1.a in Honen 6 (OUJ469, PI 307495, GSHO 1232); dsp1.a from DWS 1081 in Bowman (PI 483237)*7 (GSHO 1833). | 1513803 | GSHO 1232 |
