Locus name: Breviaristatum-f
Locus symbol: ari-f
Previous nomenclature and gene symbolization:
Breviaristatum-21 = ari-21 (1, 2).
Inheritance:
Monofactorial recessive (2).
Location is unknown.
Description:
Awns are thin and often 1/2 to 3/4 normal length, and awn length decreases
toward the top of the spike. Spikes are more lax and have fewer rachis
internodes than those of parental cultivars. Deformation of the lemma apex
causes apical kernels to be naked (2).

Description:
Plants are semidwarf (3/4 of normal culm length) and awns are about 5/6 normal
length. The peduncle is short and coiled or kinked, and as a result the spike
rarely emerges above the flag leaf (2).

maturity. Variability in awn length is observed over environments and awns seem
thinner than normal (2). Awns of plants grown in fall greenhouse nurseries at
Fargo, North Dakota, USA, are very short and thread-like.

Location is unknown.
Description:
Awns are 3/4 normal length and arise at an oblique angle, and they are
drastically shortened towards the top of the spike. Plant height is normal, but

Locus name: Erectoides-f
Locus symbol: ert-f
Previous nomenclature and gene symbolization:
Erectoides-18 = ert-18 (2).
Inheritance:
Monofactorial recessive, but some partial dominance is expressed (2, 5).
Located in chromosome 4HS?, an association with the int-c (intermedium
spike-c) locus is reported (1), but the association could be caused by a
pleiotropic effect of the ert-f gene and not linkage.
Description:
Spikes are semicompact with average rachis internode length values from 2.2 to
2.6 mm. Culm length is about 5/6 of normal (5). Sterile lateral spikelets are
larger than those of normal sibs, but apices are rounded.

Description:
Plants are semidwarf (about 3/4 normal height), and spike density is increased
only slightly (3). Maturity may be somewhat delayed. Because selection of
ert-h plants is difficult in crosses to Bowman, and the identity of the
gene in the Bowman backcross-derived line needs to be rechecked.

Previous nomenclature and gene symbolization:

Inheritance:
Monofactorial recessive (3, 4).

Description:
Early heading mutants at the mat-b locus show a rather drastic increase
in earliness (heading 7 days earlier than the parents) under field cultivation
in Sweden (3). When grown under controlled environmental conditions, mutants
are photo- and thermoperiod sensitive and are classified as a pronounced
long-day type (1, 2, 5). Early heading is also associated with decreased culm
length, kernels per spike, and grain yield. Mutant plants are generally more
productive in field trials than mat-a (eam8) mutants, but less
resistant to lodging, partially caused by a modified culm structure. Compared
with the original cultivars, they have one internode less per culm, a longer
first internode, and a short basal rachis internode (3). At an early stage of
development, mat-b mutants are characterized by pale green color when
grown at 15 to 20oC, but they are bright green in color at lower
temperatures (1, 2, 5).

long-day type (2). Early heading is also associated with increased culm length
and grain yield. The length of the peduncle is increased and mutants have
longer spikes. Compared with the drastic maturity mutants at eam8
(mat-a), mat-b, and mat-c loci, mutants at the
mat-d locus have a normal number of the culm internodes (1, 3). Plants
with narrow leaves are observed in progenies from crosses to Bowman.
Origin of mutant:
An X-ray induced mutant in Bonus (PI 189763) (3).
Mutational events:
mat-d.14 in Bonus (3); mat-d.124 in Foma (CIho 11333) (5, 6,
7).
Mutant used for description and seed stocks:
mat-d.14 in Bonus (GSHO 1790).

Locus name: Praematurum-e
Locus symbol: mat-e
Previous nomenclature and gene symbolization:
Praematurum-18 = mat-18 (3).
Inheritance:
Monofactorial recessive (2).
Location is unknown.
Description:
Early heading mutants at the mat-e locus show a rather drastic increase
in earliness (heading 6 days earlier than the parents) under field cultivation
in Sweden (1, 4, 5). When grown under controlled environmental conditions, the
mutant mat-e.18 is photo- and thermoperiod insensitive (1). Mutants have
a pronounced short-day type of photoperiod response (1, 3, 6). A slight delay
in heading and less photoperiod neutrality is associated with other alleles at
this locus (4).

A neutron induced mutant in Bonus (PI 189763) (6).

subtending the lowest spikelet is always the largest, embracing in some cases
about one-half the spike. Bracts become progressively smaller toward the tip of
the spike. Mutants have elongated basal rachis internodes (2, 3).

Locus name: Albino seedling 10
Locus symbol: abo10
Previous nomenclature and gene symbolization:
White seedling t2 = at2 (1).
Albino seedling t2 = at2 (2).
Inheritance:
Monofactorial recessive and expressed in the endosperm as a xenia effect (1).
Location is unknown.
Description:
Seedlings are very weak and white in color (1). A xenia effect of the
abo10.j gene on seed size is described in Robertson (1). 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 (1).
Plants with this phenotype are classified as albino mutants (2). The
abo10.j gene must be maintained as a heterozygous stock.
Origin of mutant:
A spontaneous mutant in Canadian Thorpe (PI 2710) (1).
Mutational events:
abo10.j in Canadian Thorpe (Canadian Thorpe I) (1).
Mutant used for description and seed stocks:
abo10.j in Canadian Thorpe (GSHO 57).
