In some environments, secondary or tertiary tillers may show a drastic reduction in stem in stem internode, spike, and awn length. Awns are thin and brittle and may flare somewhat on later tillers. Kernels are thin with fine wrinkles on the lemma. Inheritance: Monofactorial recessive. Located in chromosome 3HS, probably less than 2.4 cM from the centromere.

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-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.

Spikes are relatively short and show a slight reduction in rachis internode length with a range of values from 2.7 to 3.0 mm. Inheritance: Monofactorial recessive. Located in chromosome 3HL, over 6.6 cM distal from the centromere. Previous nomenclature and gene symbolization: Erectoides-79=ert-79. Mutational events: ert-ii.79 in Bonus.

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.

| 7 | GSHO 572 | lbi2.b | Hordeum vulgare L. subsp. vulgare | Ontario, Canada | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | Mutant plants in the cultivar Montcalm have a marked elongation and weakness of the basal rachis internode of the spike. This region may be 10 to 13 cm long in some tillers. The spike hangs vertically downward from the collar on emergence from the sheath and is often broken off in this region by the wind. Even when not broken off, spikes have a high degree of sterility and contain poorly filled grain. Plants show delayed maturity. The ert-i mutants in Bonus have an erect, semicompact (rachis internode length ranging from 2.3 to 2.9 mm) spike, an elongated (2 to 4 cm) basal rachis internode, and reduced plant height (3/4 normal). Removal of modifiers in the Montcalm and Bonus mutant stocks by backcrossing resulted in Bowman backcross- derived lines having similar phenotypes. Inheritance: Monofactorial recessive. Located in chromosome 4HL, less than 12.8 cM proximal from the Kap (hooded lemma) locus, about 2.4 cM proximal from the Kap locus, and about 18.5 cM proximal from the glf1 (glossy leaf 1) locus.
