140	GSHO 2475	Lys4.d	Hordeum vulgare L. subsp. vulgare	Denmark	NSGC		1996	DEVELOPED			Genetic material	At the hard dough stage, kernels homozygous for the Lys4.d gene develop a depression near the center of the lemma, which becomes progressively more distinct as the kernels mature. Grain produced by mutant plants has a 9% increase in lysine content. Shrunken endosperm has a pleiotropic association with the high lysine gene Lys4.d. Kernels heterozygous at the Lys4 locus may develop a slightly less distinct depression on the dorsal side. Maintenance of Lys4.d stocks may be difficultu because outcrosses are not recognized easily. Inheritance: Monofactorial incomplete dominant. Located in chromosome 1HS [5S], over 35.1 cM distal from the ert-b (erectoides-b) locus.

The depression is similar in size to that produced by sex1 (shrunken endosperm xenia 1) mutants. The mutant expresses xenia permitting classification of kernels from heterozygous plants as normal or shrunken with an expected 3:1 ratio. Field establishment and growth of mutant plants is normal. Inheritance: Monofactorial recessive. Located in chromosome 7HS [1S], about 2.8 cM distal from the seg2 (shrunken endosperm 2) locus, about 3.1 cM from the centromere, and over 45.8 cM proximal from the Est5 (esterase 5) locus.

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.

When grown at Langdon, North Dakota, USA, dwarf plants are difficult to identify in progenies from crosses between OUM142 and two-rowed spring barley. The frequency of dwarf, late maturing plants is low because sld2.b is linked to an Eam1 (early maturity 1) allele in the repulsion phase. Inheritance: Monofactorial recessive.

145	GSHO 2492	sls1.a	Hordeum vulgare L. subsp. vulgare	North Dakota, United States	NSGC		1996	DONATED	04/1996		Genetic material	Sterile lateral spikelets become progressively smaller toward the tip of two-rowed spikes in plants, which express the Vrs1.b and int-c.b alleles at the six-rowed spike 1 and intermedium spike-c loci, respectively. The terminal rachis nodes generally have rudimentary lateral spikelets. Expression of the sls is affected by genetic background, but often is stronger in late tillers. The trait can be observed only in some two-rowed segregates from crosses between six- and two-rowed cultivars. The sls phenotype can be observed in plants of the Bowman backcross-derived line for the msg1.ca gene. Two-rowed segregates in the Harrington/Morex doubled haploid population show the typical range of expressions associated various combinations of sls and int-c alleles.	1545056	GSHO 2492

In meristematic tissues of root tips and young shoots, polyploid nuclei consisting of 4x, 8x, and sometimes many more chromosomes are gound together with normal diploid cells. Epridermal cells of the leaves are sometimes irregular and variable in shape and size. The mixoploid condition of tissues is believed to result from incomplete cytokinesis following nuclear division. Plant vigor in the Bowman backcross-derived line is very sensitive to environmental stress. When grown in the greenhouse, the plants are 2/3 normal height, spike size and length are reduced, and leaves are narrow.

208	GSHO 988	Blp1.b	Hordeum vulgare L. subsp. vulgare	Utah, United States	NSGC		1995	DEVELOPED			Genetic material	Black pigmentation of the lemma and pericarp develops slightly before maturation of the spike. Pigmented organs may include all parts of the spike, awns, the upper portion of the stem, and upper leaves. The intensity of pigmentation associated with each of the dominant alleles at the Blp locus is characteristic of that allele, and is relatively stable over environments. Black seed is produced by melanin-like pigment in the pericarp. Woodward reports that the dominance ranking of alleles at the Blp locus is related to the intensity of black pigmentation they confer with the Blp.1.b (B) allele conferring extreme black pigmentation. The Blp1.mb (Bmb) allele is associated with medium black and a reduced distribution pattern; and the Blp1.g (Bg) allele is associated with light black or gray coloration.

237	GSHO 1316	Early maturity	Hordeum vulgare L. subsp. vulgare	Colorado, United States	NSGC		1994	DONATED	05/1994		Genetic material	This gene controls the strong response of some cultivars to photoperiod. The Eam1 gene is described as a simply inherited dominant and the main factor for early maturity. Under long-day condition, a near-isogenic line with Eam1 is reported to be 7 to 8 days earlier than the eam1 line 'ea1'. The early maturity gene is weakly linked to the vrs1 (six-rowed spike 1) locus. In North Dakota, USA, progenies from crosses of Bowman to Hordeum vulgare subsp spontaneum and Coast, facultative winter, northern spring (from Finland and Alaska), and winter types of barley, extremely early segregates are found. A linkage between early maturity and malformed spikes (com2) is observed when an accession from the ICARDA-CIMMYT collection of barley freaks is backcrossed to Bowman. Positive linkage data are found also in progenies from some crosses between a line having the com2 - eam1 recombinant and early segregates from the above crosses. The Eam1 locus in barley is likely homoeologous to the Ppd1, Ppd2, and Ppd3 loci in wheat, which control strong photoperiod response.	1513721	GSHO 1316

The character shows variable expression in some crosses, and is seen in only a few spikes of affected F2 plants. The trait isolated in the Bowman backcross-derived line is expressed in six-rowed progeny as a malformed rachilla in some lateral spikelets. The rachilla malformation is most pronounced in the middle of the spike and ranges from formation of a fertile floret to slight elongation of the rachilla. However, confirmation that this trait is the same gene as in the original stock has not been completed. Inheritance: Monofactorial recessive.

Affected tillers are weaker and often abort under moderate to severe heat and moisture stress. In some environments, the whole plant becomes a golden yellow prior to maturation. Inheritance: Monofactorial recessive, the deviation from 3:1 reported by Walker et al. may be caused by genotype-environment interactions. Located in chromosome 2H, about 19.9 cM distal (probably) from the vrs1 (six-rowed spike 1) locus. Previous nomenclature and gene symbolization: None.

Later leaves have patches of bright yellow. Cool temperatures enhance the yellow banding while warm temperatures increase green pigments. Under very cold conditions, leaves become yellowish white and deteriorate. Heterozygotes have slightly pale green color compared to normal plants. The zeb3.c gene must be maintained as a heterozygous stock. Mutational events: zeb3.c in an unknown cultivar (Utah 41, Alb Acc 43).

Lateral spikelets have perfect flowers and complete fertility. The lr trait is expressed only in six-rowed barley, and heterozygotes have a short awn on the lemma of lateral spikelets. Since recombination with neither vrs1.a(v) nor Vrs1.b (V) alleles was observed, the lr or vrs1.c phenotype is likely controlled by an allele at the vrs1 locus. The Bowman backcross- derived line for the vrs1.c gene has short, stiff awns on the central spikelets (about 1/3 normal length) and no awns on the lateral spikelets.Inheritance: An incomplete dominant in the multiple allelic series at the vrs1 (six-rowed spike 1) locus.

262	GSHO 196	vrs1.a	Hordeum vulgare L. subsp. vulgare	Colorado, United States	NSGC		1994	DONATED	05/1994		Genetic material	Alleles at this complex locus modify development of the lateral spikelets and the associated lemma awn. The vrs1.a allele (v gene) is present in most six-rowed cultivars and produces well-developed lateral spikelets. The lemma awn of lateral spikelets will vary from 3/4 to nearly as long as those of central spikelets, depending upon alleles present at other loci. The Vrs1.b allele (V gene, distichon) is present in many two-rowed cultivars and reduces lateral spikelets to sterile bracts with a rounded tip. The Vrs1.t allele (Vt gene, deficiens) causes an extreme reduction in the size of lateral spikelets. The lr or vlr (vrs1.c) gene in Nudihaxtoni and Bozu types will not recombine with the vrs1.a allele and produces phenotypes similar to the Vrs1.d allele (Vd gene) of Svanhals. The series of induced mutants in two-rowed barley called hex-v and Int-d mutants differ in the size of lateral spikelets, but they interact with the vrs1.a allele as incomplete dominants. Many heterozygous combinations with vrs1.a have a pointed tip on the lemma of sterile lateral spikelets. Alleles at the int-c (intermedium spike-c) locus modify lateral size in the presence of vrs1.a, Vrs1.b, and Vrs1.d, but not when Vrs1.t is present.

Homozygosity for the Vrs1.d allele and the int-c.b (formally i) allele at the int-c (intermedium-c) locus prevents the development of ovules and awns in lateral spikelets. The Vrs1.d allele interacts with the Int-c.a (formally l) allele to cause development of a few fertile lateral spikelets. Presence of the Int-c.h (formally lh) allele contributes to a greater number of lateral kernels than Int-c.a.

285	GSHO 35	ddt1.a	Hordeum vulgare L. subsp. vulgare	Idaho, United States	NSGC		1994	DEVELOPED			Genetic material	The recessive allele, ddt1.a confers resistance to the insecticide DDT. Susceptible plants show severe chlorosis followed by yellowing and death about 10 days after spraying seedlings at the 2- to 3- leaf stage with a concentration of 1 part per 500 in water. A second application about 7 days after the first will insure complete kill of susceptible seedlings. The DDT solution affects only the leaf it comes in contact with it; thus, plants can be classified for reaction to DDT about anthesis by dipping a single leaf into the DDT solution. The part of the leaf blade covered by solution on susceptible plants will turn yellow and die, whereas it will remain green on resistant plants. The frequency DDT susceptibility in collections is about 10%, nearly 40% in two-rowed entries and 1% in six-rowed ones. Inheritance: Monofactorial recessive.

Rachis internode length averaged from 2.0 to 2.8 mm among the alleles at the ert-m locus. However, the rachis internodes within each spike are often variable in length and the spike appears irregular similar to those of opposite spikelet mutants. Plants with an allele at the ert-m locus are often 10 to 15 cm shorter than parental cultivars, and some tillers of most plants have one or more extremely shortened upper internodes. Alleles at the ert-m locus responded positively to GA3 treatments designed to increase internode length. Some alleles at the ert-m locus lack normal anthocyanin pigmentation. This trait could not be separated from the ert-m allele and was shown to be allele at the ant1 locus. Inheritance: Monofactorial recessive.

Most mutants at this locus had a similar decrease in rachis internode length, which varied from 1.9 to 2.4 mm. Mutant lines are about 3/4 normal height. The spike has enlarged lateral spikelets that have a pointed or awnletted tip and plants show partial sterility not associated with a translocation. Spikes tend to have a whitish color at maturity. Spike density is decreased by GA3 treatment of plants as the flag leaf emerges. In the Bowman backcross-derived stock, plants homozygous for the ert-n.51 gene produce few tillers and mature later than normal sibs. Inheritance: Monofactorial recessive.

When grown in the fall at Kurashiki, Japan, plants head about 20 days earlier than the standard mid-season cultivar, Akashinriki, because they are day-length neutral or photoperiod insensitive. Day-length neutrality is observed in the Swedish early heading mutants, which were induced in spring barley. under controlled environmental conditions, number of days to heading does not change as photoperiod is altered. Plants become yellow green in response to specific growing conditions, 8 to 12 hours of illumination at low temperatures (below 10 degrees C) plus high temperature (20 degrees C or higher) during the dark period. All the mat-a induced mutants are characterized by yellowish-green seedlings at an early stage of development under controlled environmental conditions. The color change is caused by photothermal stress, which increases the zeaxanthin content at the expense of chlorophyll and other pigments. The mutant stock mat-a.8 was released as the cultivar Mari.

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.

The xenia effect of the abo10.j gene on seed size was described in Robertson. Seeds, which are homozygous for this seedling lethal gene, are shriveled with a 1000-kernel weight of 23.4 g compared with 46.5 g for normal kernels. After germination, the endosperm turns watery instead of pasty as found with normal seeds. Later, plants with this phenotype were classified as albino mutants. The abo10.j gene must be maintained as a heterozygous stock. Inheritance: Monofactorial recessive and expressed in the endosperm as a xenia effect. Location is unknown.

362	GSHO 575	sgh1.a	Hordeum vulgare L. subsp. vulgare	Colorado, United States	NSGC		1994	DONATED	05/1994		Genetic material	The sh1.a allele conditions a highly spring habit (grade 1) and plants readily form ear primordia under long-day conditions without prior cold treatment. However, the type cultivar, Iwate Mensury C, and some other cultivars, which are homozygous for the sgh1.a allele, behave as a winter type when sown in the fall (short-day condition). When near-isogenic lines for growth habit were grown at Kurashiki, Japan, the sgh1.a allele had little influence maturity of phenotype in the presence of the other spring habit growth genes. Cultivars having only the sgh1.a allele for spring habit are rare. The sgh1.a allele is found rarely in spring barley cultivars from Tibet. Inheritance: Monofactorial recessive.

385	GSHO 701	Rpg1.a	Hordeum vulgare L. subsp. vulgare	Wisconsin, United States	NSGC		1994	DEVELOPED			Genetic material	The dominant allele at the Rpg1 locus confers moderate resistance to most races of Puccinia graminis f sp tritici. Lesion size and percent stem and leaf sheath infection in adult plants is reduced compared with susceptible plants under field conditions. At high temperatures (greater than 20 degrees C), differentiation of seedling reaction types is observed with race 56 (10). These differences correlate with adult plant reactions better than at lower temperatures. Differences among cultivars indicate that a modifier of the Rpg1.e allele exists. Plants with Rpg1 gene show a susceptible reaction to pathotype QCC of Puccinia graminis f sp tritici and to Puccinia graminis f sp secalis. Molecular markers closely linked to the three different sources of the Rpg1 region gene suggest that they originated independently.

Stand establishment is poor under field conditions. Xenia effects were not observed in the original study, but the stock presently held as GSHO 753 and the Bowman backcross-derived line show xenia effects in hybrid plants. The lemma side of the kernel has a very distinct depression in mature seed. Inheritance: Monofactorial recessive. Located in chromosome 7HL [1L], over 34.0 cM from the centromere.

403	GSHO 764	Sgh3.c	Hordeum vulgare L. subsp. vulgare	Japan	NSGC		1994	DEVELOPED			Genetic material	Cultivars with the Sgh3.c allele exhibit a highly spring habit (grade 1) and plants form ear primordia under long-day conditions without prior cold treatment. When near-isogenic lines for growth habit were grown at Kurashiki, Japan, the Sgh3.c allele had major influence on maturity and phenotype in the absence or presence of the other spring habit of growth genes. Plants were 10 days or more earlier, tillers per plant were 30% less or more, kernel number was reduced by about 20%, and spike length was reduced. Spring cultivars having only the Sgh3.c gene have never been found. Spring cultivars with the Sgh2.b Sgh3.c genotype occur most frequently in North Pakistan, North India, Tibet, Ethiopia, and Northern Europe. The Sgh3.c allele is always accompanied by the Sgh2.b or sgh1.a and Sgh2.b alleles in cultivars. Inheritance: Monofactorial dominant. Located in chromosome 1HL [5L], over 35.4 cM proximal from the Blp (black lemma and pericarp) locus. Previous nomenclature and gene symbolization: Spring habit of growth 3=Sh3.

Plants with the Sgh2.ll gene (grade II type) are 10 days or more later than those with Sgh2.l, and require about 10 days of pre-chilling to make up the difference in heading time. Complex interactions with genotype and other spring growth havits have been reported. The Sgh2.ll allele is prevalent in the Oriental region, while the Sgh2.l allele is confined to the Occidental region. Inheritance: Monofactorial dominant, but a multiple allelic series exists with the alleles for the highest grade of spring habit dominant over those for less spring-like habit. The dominant alleles are epistatic to the winter habit alleles at the sgh1 and Sgh3 loci. Located in chromosome 5HL [7L], over 15.1 cM distal from the raw1 (smooth awn 1) locus.

409	GSHO 775	vrs4.k	Hordeum vulgare L. subsp. vulgare	Japan		Historic	1994	DEVELOPED			Genetic material	Alleles at this locus enhance the development of lateral spikelets and formation of additonal spikelets to various degrees. The int-e mutants, which were isolated in two-rowed cultivars, have enlarged lateral spikelets that may set seed in the upper two-thirds of the spike. Kernels in lateral spikelets are smaller than those from central spikelets in int-e mutants. The rachilla may be deformed by partial formation of an extra spikelet. The awn size on lateral spikelets range from a pointed apex to 3/4 normal length. The mul1.a and vrs4.k alleles, which were isolated in six-rowed cultivars, may produce numerous extra spikelets at the base of the lateral spikelets and on the rachilla. Phenotypic differences among alleles are retained in the Bowman backcross-derived lines. Inheritance: Monofactorial recessive. Located in chromosome 3HL, about 27.5 cM distal from the uzu (uzu) locus. Previous nomenclature and gene symbolization: Multiflorus=mul. Intermedium spike-e=int-e. Six-rowed spike 4=v4.

410	GSHO 776	vrs5.n	Hordeum vulgare L. subsp. vulgare	Colorado, United States		Historic	1994	DONATED	05/1994		Genetic material	Alleles at the int-c (vrs5) locus alter the size of lateral spikelets. The lemma apex of lateral kernels is rounded or weakly pointed, awnless or short-awned. Lower lateral spikelets may develop poorly in some int-c mutants, while seed development may occur in all lateral spikelets of others. Variability in lateral spikelet development among the int-c mutants is responsive, also, to environmental conditions. The Int-c.a (formally l) allele in six-rowed barley increases the size of lateral spikelets, while the int-c.b (formally i) allele in two-rowed barley prevents anther development in lateral spikelets. The int-c.5 mutant n Bonus produces fertile stamens in lateral spikelets. in the presence of the Int-c.h (formally lh) allele of Mortoni, lateral spikelets are male fertile and may occasionally set seed. Spikes of vrs5.n plants appear similar to the six-rowed spike, but lateral spikelets are smaller (less than half the size of the central spikelets) and broader. Inheritance: Monofactorial recessive. Located in chromosome 4HS, about 13.1 cM proximal from the fch9 (chlorina seedling 9) locus, and about 14.5 cM distal from the Kap (hooded lemma) locus.

411	GSHO 833	lnt1.a	Hordeum vulgare L. subsp. vulgare	Japan	NSGC		1994	DEVELOPED			Genetic material	The tiller number is reduced to 2 to 4 per plant. These tillers are formed soon after seedling emergence; hence, no late-emerging tillers are observed. Culms are thick and stiff and leaves are dark green. Spike malformations occur in most environments. The spike may have irregular rachis internode lengths and is relatively short. The lower portion of the spike appears more dense. Lateral spikelets in two-rowed cultivars are enlarged and have a pointed apex. Plants homozygous for a recessive allele at the lnt1 locus head slightly earlier than normal sibs. Inheritance: Monofactorial recessive. Located in chromosome 3HL, about 30.5 cM distal from the uzu (uzu) locus. Previous nomenclature and gene symbolization: Reduced number of tillers=rnt.

412	GSHO 835	Lga1.a	Hordeum vulgare L. subsp. vulgare	Alberta, Canada		Historic	1994	DEVELOPED			Genetic material	In spikelets of plants with the dominant allele (Lga1.a), the glume (outer) plus its awn is much longer than the kernel. Heterozygotes have a glume awn of intermediate length. In the short glume awn phenotype (lga1.b), the glume length and width are unaltered, but the glume awn is 4 to 6 mm for the short type and 11 to 13 mm for the long type. Recessive alleles at the eog locus (GSHO 1592) produce an array of glume sizes, some of which have glumes phenotypically similar to those associated with the dominant allele at the Lga locus. However, all eog alleles have wider than normal glumes and show a recessive inheritance pattern. Inheritance: Monofactorial dominant. Location is unknown. Previous nomenclature and gene symbolization: Long glume awn=L. Long outer glume=Log; Helgason used the gene symbol log for the short glume awn type, but this symbol is also used for the elongated outer glume (eog) gene.

413	GSHO 842	btr2.b	Hordeum vulgare L. subsp. vulgare	Japan	NSGC		1994	DEVELOPED			Genetic material	Joints at the rachis nodes are tough or non-britle, which prevents segmentation or disarticulation of the rachis prior to maturity. Plants homozygous for the btr2.b allele do not shatter prior to harvest in contrast to wild barley (Hordeum vulgare subsp spontaneum). All cultivars with the btr2.b allele have a dominant allele at the Btr1 locus. When crossed to cultivars with the btr1.a allele at the Btr1 locus (genotype btr1btr1Btr2Btr2), F1 plants have a brittle rachis. The segregation ratio in the F2 generation is 1 brittle: 1 tough rachis. The majority of the cultivars (mostly six-rowed) distributed in Oriental region of the Old World have the btr2.b allele. Inheritance: Monofactorial recessive in crosses to Hordeum vulgare subsp spontaneum.
