| 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.
