Stock number: BGS 451
Locus name: Eceriferum-yh
Locus symbol: cer-yh
Previous nomenclature and gene symbolization:
Inheritance:
Monofactorial recessive (3).
Located in chromosome 3HS, based on linkage drag with the Btr (brittle
rachis) locus (1).
Inheritance:
Surface wax coating on the spike appears absent (wax code - ++ ++) (3). Mutant
plants are semi-sterile, heading is delayed, and lateral spikelets have a
pointed apex. In the Bowman backcross-derived line, seed set is low because few
hairs develop on the stigma. Although the anthers are slightly malformed, male
fertility is good.
Origin of mutant:
An X-ray induced mutant in Bonus (PI 189763) (2).
Mutational events:
cer-yh.116, -yh.654 in Bonus (3).
Mutant used for description and seed stocks:
cer-yh.116 in Bonus (GSHO 1541); cer-yh.116 in Bowman (PI
483237)*5 (GSHO 1947).

Locus name: Non-blue aleurone xenia 5
Locus symbol: blx5
Previous nomenclature and gene symbolization:
Non-blue aleurone 5 = bl5 (1).
Inheritance:
Monofactorial recessive when complementary dominant alleles are present at the
Blx1, Blx2, Blx3, and Blx4 loci (1).
Located in chromosome 7HL [1L] (1, 5), associated with a red stem trait
controlled by the dominant allele at the ant5 (anthocyanin-less 5) locus
(1); linked to the blx2 (non-blue aleurone xenia 2) locus, but not to
the fch12 (chlorina seedling 12) locus (5).
Inheritance:
Blue aleurone color is due to anthocyanin pigments (4) which occur as lumps
inside many aleurone granules in some or all aleurone cells (1). Variation in
blue color expression from dark blue to an off-white is caused by environmental
factors and modifying genes (1, 2). Aleurone color is best observed in well
filled grain that is magnified to show individual aleurone cells, after more
superficial tissues have been peeled off (3).
Origin of mutant:
Natural occurrence in BGM 122 (1).
Mutational events:
Mutant used for description and seed stocks:
blx5.e in BGM 122 (GSHO 2509).

Locus name: Zebra stripe 2
Locus symbol: zeb2
Previous nomenclature and gene symbolization:
Zoned leaf = zd (2).
Zoned leaf = z (3, 5, 11).
Zoned leaf c = zbc (5, 10, 12).
Zebra leaf or zoned Colorado = zc (4, 11).
Zebra striped leaves = zd (6).
Zebra stripe 2 =zb2 (11).
Chlorina seedling 10 = f10 (1, 8).
Inheritance:
Monofactorial recessive (2, 3, 9).
Located in chromosome 4HL (1, 2), about 9.3 cM distal from the Kap
(hooded lemma) locus, and about 17.0 cM proximal from the glf3 (glossy
leaf 3) locus (1).
Inheritance:
Leaves are chlorina throughout the life cycle, independent of light and
temperature (2). Plants may be killed by low temperature during the winter when
normal plants are unaffected (2). A zonate pattern of different degrees of
chlorina is observed in seedling leaves. After much confusion about this gene,
the locus was named zebra stripe 2 = zb2 (11). Plants are very weak or
non-viable in the field in North Dakota, but only reduced vigor is noted when
grown in the greenhouse.

Mutational events:
zeb2.b in an unknown cultivar (2, 3, 9, 11); fch10.s in an
unknown cultivar (GSHO 1234) (7, 8); both stocks may have originated from the
same mutant used by Woodward (12) and first isolated by Immer and Henderson
(2).

Inheritance:
Monofactorial recessive (1, 2).
Located in chromosome 3HS, may be linked to the btr2 (non-brittle rachis
2) locus based on linkage drag (1); trisomic analyses of the yst3 locus
have not been successful (3, 4, 5).
Inheritance:
Yellow streaks of variable width and number develop in the leaves, stems, and
spikes of homozygous plants. Some plants are almost entirely yellow, similar to
chlorina plants. Penetrance is 100%, but expressivity is highly variable and
may require careful observation. Cold treatment increases the number and width
of the yellow streaks (1).

Inheritance:
Monofactorial recessive (2).
Location in chromosome 2H is possible (3, 4, 7, 8), and a possible linkage drag
association with the Gth (toothed lemma) locus in chromosome 2H is noted
(1).
Inheritance:
Culm length and diameter, leaves, spikes, and glumes are greater than the
control; awns are shorter than the control; leaves are dark green; spikes are
lax; spikes, culms, and leaf sheaths have a heavy wax coating (5). Anther
development is good, but the stigma has few hairs and seed set is poor (2, 5).
In the Bowman backcross-derived line, plant height is normal and plants appear
normal except spikelets are abnormal and the wax coating is heavy. The lemma is
large and long, awns are 1/2 normal length, stigma hairs are few, and selfed
seed set is 10 to 15%. Hand pollination can increase seed set.

Previous nomenclature and gene symbolization:
Male sterile av = msg,,av (2).
Male sterile = 63msy1 (2).
Inheritance:
Monofactorial recessive (2, 5).

Heterozygotes show reduced fertility (75 to 85% seed set), and male sterile
plants always have a long glume awn (Lga) trait from Paragon. Thus, the
msg34.av allele probably involves a translocation between chromosome 6HS
and an unknown chromosome.

Inheritance:
The spike is branched from the rachilla of the bottom 1 to 10 spikelets. Awns,
which vary from normal to thread-like, and protruding branches are bent in
various directions because of "packing" problems in the boot (4). More spike
branches develop under favorable environmental conditions.

ari-e (breviaristatum-e) locus (4, 12), and about 3.1 cM from the
ert-g (erectoides-g) locus (4, 11, 12).
Inheritance:
Florets have five anthers with two developing from transformed lodicules (2,
14). The grain is thin and angular and caryopses are exposed between the lemma
and palea. The awn has a very wide base, without a distinct notch in the lemma
attachment region. Rachis internodes are 13% longer than normal. Tillers arise
at oblique angles giving isolated plants an appearance of a tufty growth habit
(5). Treatment of leaves after tillering with GA3 increases rachis
internode length (13).

Male sterile bk = msg,,bk (5).
Male sterile = 867N-89 (5).
Inheritance:
Monofactorial recessive (5).
Located in chromosome 6HS (1), about 10.8 cM distal from the rob (orange
lemma) locus (1, 2, 8).
Inheritance:
Selfing - about 1.1% (5).
Outcrossing - complete female fertility (5).
Stamens - anthers nearly normal sized with stomium and filament elongation
(5).
Origin of mutant:
A spontaneous mutant in Betzes (PI 129430) (5).
Mutational events:
msg36.bk in Betzes (MSS325) (4, 5, 7); msg36.eg in Pavo P57
(MSS382) (3, 6).
Mutant used for description and seed stocks:
msg36.bk in Betzes (GSHO 2388); msg36.bk in Bowman (PI 483237)*7
(GSHO 2067).

Locus name: Male sterile genetic 37
Locus symbol: msg37
Previous nomenclature and gene symbolization:
Male sterile hl = msg,,hl (2).
Inheritance:
Monofactorial recessive (2, 3).
Location is unknown, but is not located in chromosome 2H (4).
Inheritance:
Selfing - none to 6% or more (2), the degree of selfing seems sensitive to
environmental conditions, favored by cool conditions.
Outcrossing - complete female fertility (2).
Stamens - anthers shrunken, no stomium or filament elongation (3) to nearly
normal (2).
Origin of mutant:
A spontaneous mutant in Clermont (PI 343724) (2).
Mutational events:
msg37.hl in Clermont (MSS465) (1, 2); msg37.jx (MSS529; GSHO
2389) in a dwarf mutant 17:17:2 (DWS1009) selected from Birgitta (NSGC 1870)
(1, 3).
Mutant used for description and seed stocks:
msg37.hl in Clermont; msg37.jx in Bowman (PI 483237)*7 (GSHO
2303).
