| 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-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.

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. Located in chromosome 7HS [1S], about 14.7 cM distal from the cer-f (eceriferum-f) locus, and near the ant1 (anthocyanin-less 1) locus.
