| 0 | GSHO 1655 | ari-g.18 | Hordeum vulgare L. subsp. vulgare | Skåne län, Sweden | NSGC |  | | 1996 | DEVELOPED | | | 58.98333300, 13.50000000 | | | Genetic material | Plants are semidwarf and very weak. Awns are 1/4 to 1/3 normal and stiff, spikes are short and small, and seed set is low. Leaf blades are very narrow and often involuted. When grown in the field at Fargo, North Dakota, USA, plant development is very slow, the upper portion of the sheath is white as new leaves emerge, and spikes are seldom produced. Inheritance: Monofactorial recessive. Located in chromosome 2H; the linkage drag association with the Gth (toothed lemma) locus may be caused by poor expression of the Gth1.a allele in the Bowman backcross-derived line. Previous nomenclature and gene symbolization: Breviaristatum-18=ari-18. Short awn 10-lk10. Mutational events: ari-g.18 in Bonus; ari-g.24 in Bonus; ari-g.134, -g.138, -g.142, -g.158, -g.221, -g.234, -g.246 in Foma (CIho 11333), -g.267 in Kristina; ari-g.303 in Kristina.

| 1 | GSHO 1297 | lks5.f | Hordeum vulgare L. subsp. vulgare | Montana, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Awns on both central and lateral spikelets are reduced to 1/4 or less of normal length in six-rowed cultivars. Only the central spikelets exhibit reduced awn length in two-rowed cultivars. The rachilla is often modified, and in extreme cases the rachilla may develop as an malformed additional floret. Awns are thin and brittle. Inheritance: Monofactorial recessive. Located chromosome 4HL, about 6.9 cM distal from the Kap (hooded lemma) locus. Previous nomenclature and gene symbolization: Short awn 5=lk5. Breviaristatum-2=ari-2. Breviaristatum-c=ari-c.2.

Inheritance: Monofactorial recessive. Located in chromosome 5HL [7L], very close to the raw1 (smooth awn 1) locus based on linkage drag. Previous nomenclature and gene symbolization: Breviaristatum-127=ari-127. Short awn 11=lk11. Mutational events: ari-h.127 in Foma (GSHO 1656); ari-h.127 in Bowman (PI 483237)*7 (GSHO 2125).

| 3 | GSHO 25 | brh1.a | Hordeum vulgare L. subsp. vulgare | Missouri, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Plants have short leaves, culms, spikes, awns, and seeds. The seedling leaf is about 2/3 normal length, and a similar reduction in the size of other organs is observed, but the awns are less than 1/3 normal length. Seeds are small and yields are low. The mutant phenotype is easy to classify at all stages of growth. The brachytic or semidwarf mutant was selected by L.J. Stadler and the gene symbol br was given by Powers. Inheritance: Monofactorial recessive. Located in chromosome 7HS[1S] about 9.3 cM distal from the fch12 (chlorina seedling 12) locus. Previous nomenclature and gene symbolization: Brachytic=br.

| 4 | GSHO 567 | ubs4.d | Hordeum vulgare L. subsp. vulgare | Japan | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | The stigma has only a few very short branches. This prevents normal pollen reception and reduces seed set to 13 to 30% in uzu type plants. Both the uzu1.a and srh1.a (short rachilla hair) genes interact with ubs4.d to further reduce in seed set. Pollen fertility is normal. Awn length is about 1/4 normal. Seed set on plants of the Bowman backcross-derived line varies from about 10% for plants grown in greenhouses to nearly 50% for plants grown at Aberdeen, Idaho, USA. Inheritance: Monofactorial recessive. Located in chromosome 7HL [1L], about 8.0 cM distal from the nud (naked caryopsis) locus. Previous nomenclature and gene symbolization: Unbranched style 4. Breviaristatum-15=ari-15. Breviaristatum-d=ari-d. Short awn 8=lk8.
