Anthocyanin pigments in an acid cell solution produce the red to violet color observed in the pericarp and lemma. Inheritance: Two dominant complementary genes (Pre1 and Pre2) control purple or red pigmentation of the lemma, palea, and pericarp. Located in chromosome 2HL, about 17.1 cM distal from the vrs1 (six-rowed spike 1) locus, and over 11.2 cM proximal fro the ant2 (anthocyanin-less2) locus. Previous nomenclature and gene symbolization: Purple chaff color=P. Purple chaff color=P1. Purple pericarp=P. Purple lemma =P. Red pericarp=R. Red pericarp 2=Re2.

| 4 | GSHO 27 | smooth awn 1 | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DONATED | 05/1994 | | | | | Genetic material | Barbs or teeth on the margins of the awn are absent and the size and number of barbs on the central vein are reduced. Plants homozygous for the raw1.a allele have a semi-smooth awn when other recessive genes reducing the number and/or size of the barbs are absent. The presence of these other genes may cause a complete absence of barbs on the awn. The number of stigma hairs is decreased greatly in plants homozygous for raw1.a, and reduced seed set may occur in some genotype-environment combinations. Inheritance: Monofactorial recessive. Located in chromosome 5HL [7L], about 26.8 cM distal from the srh (short rachilla hair) locus. Previous nomenclature and gene symbolization: Smooth awn=r. Smooth awn=a. Mutational events: raw1.a in Lion (CIho 923). Mutant used for description and seed stocks: raw1.a in Lion (GSHO 27); raw1.a in Bowman (PI 483237), probably from Lion via Midwestern six-rowed cultivars; Raw1 from CIho 2376 in Bowman*8 (GSHO 2124). | 1510653 | GSHO 27 |

| 8 | GSHO 51 | abo1.a | 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 abo1.a gene must be maintained as a heterozygous stock. The albino seedling mutant (line B17) studied by Daane originated in the cultivar Trebi at the University of Minnesota while Robertson reported that the abo1.a (at) stock was obtained from the University of Minnesota and is in Trebi. Although some phenotypic differences and different map positions were reported, it is possible that both authors studied the same mutant. The mutant studied by Daane has not been found in barley collections; thus, allelism tests are not possible. Inheritance: Monofactorial recessive. Located in chromosome 1HL [5L], over 22.3 cM proximal from the Blp (black lemma and pericarp) locus, and over 36.7 cM proximal from the Blp locus.

| 10 | GSHO 57 | abo10.j | Hordeum vulgare L. subsp. vulgare | Colorado, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Seedlings are very weak and white in color. 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. Previous nomenclature and gene symbolization: White seedling t2=at2. Albino seedling t2=at2. Mutational events: abo10.j in Canadian Thorpe (Canadian Thorpe 1).
