| 0 | GSHO 468 | ert-a.6 | Hordeum vulgare L. subsp. vulgare | Skåne län, Sweden | NSGC |  | | 1994 | DEVELOPED | | | 58.98333300, 13.50000000 | | | Genetic material | Spikes of all alleles have a compact appearance caused by a reduction in rachis internode length, estimated from length of ten rachis internodes. Among the alleles at the ert-a locus, rachis internode length ranged from 1.7 to 2.6 mm. The ert-a.6 allele produces plants with shorter internodes than most other ert-a alleles. Plants with an allele at the ert-a locus are 10 to 15 cm shorter than parental cultivars. The effects of the ert-a mutants on spike density are partially reversed by GA3 treatments. Plants of the Bowman backcross-derived line retained the above traits and headed 3 to 6 days earlier than Bowman. Inheritance: Monofactorial recessive. Located in chromosome 7HS [1S], about 11.4 cM distal from the cer-f (eceriferum-f) locus and about 11.7 cM distal from the nud (naked caryopsis) locus.

Among the alleles at the ert-b locus, rachis internode length varied from 1.9 to 2.3 mm. Culms are shorter than those of parental cultivars. Spike density is decreased by GA3 treatment of plants as the flag leaf emerges. Plants of the Bowman backcross-derived lines have relatively short peduncles and are about 3/4 normal height. Inheritance: Monofactorial recessive. Located in chromosome 1HL [5L], slightly distal from the cer-e (eceriferum-e) locus, and about 19.3 cM proximal from the nec1 (necrotic leaf spot 1) locus. Previous nomenclature and gene symbolization: Erectoides-2=ert-2.

| 2 | GSHO 471 | ert-c.1 | Hordeum vulgare L. subsp. vulgare | Skåne län, Sweden | NSGC |  | | 1994 | DEVELOPED | | | 58.98333300, 13.50000000 | | | Genetic material | Spikes have a compact or semicompact appearance caused by a reduction in rachis internode length. Among the alleles at the ert-c locus, rachis internode length had a continuous range from 1.7 to 2.9 mm. The spike has fusiform shape with shorter rachis internodes at the base and longer ones near the apex. The culm length is also highly variable among mutants at the ert-c locus. Mutants ert-c.66 and ert-c.153 are partially sterile, much shorter in culm length, and have a more bushy growth pattern than other mutants at this locus. Spike density is decreased by GA3 treatment of plants as the flag leaf emerges. The Bowman backcross-derived line for ert-c.1 is later and taller than Bowman. Inheritance: Monofactorial recessive. Located in chromosome 3HL, about 3.7 cM from the centromere, and about 2.9 cM proximal from the msg5 (male sterile genetic 5) locus. Previous nomenclature and gene symbolization: Erectoides-1=ert-1.

Among the alleles at the ert-d locus, rachis internode length ranged from 1.5 to 1.8 mm for mutants of group one and 2.1 to 2.7 mm for mutants in group two. The ert-d.7 allele is in the group two based on rachis internode lengthh and is closely linked to the translocation point. Plants with an allele at the ert-d locus were placed in two plant height groups, but mutants with compact spikes were not all in the short plant height group. Plants with alleles at the ert-d locus responded positively to GA3 in studies on internode length. Inheritance: Monofactorial recessive. Located in chromosome 7HS [1S], near the ert-a (erectoides-a) locus, and about 4.5 cM distal from the cer-f (eceriferum-f) locus. Previous nomenclature and gene symbolization: Erectoides-7=ert-7.
