BGS 724, Short awn 6, lks6

BGN  43:219
Stock number: BGS 724
Locus name: Short awn 6
Locus symbol: lks6

Previous nomenclature and gene symbolization:

Short awn q = lks.q (2).


Monofactorial recessive (2, 3).
Located most likely in chromosomes 1H, 5H, or 6H (1); lks6.q is associated with large groups of SNP markers in 1H [2_1134 to 2_1361 (positions 64.79 to 82.35 cM) in 1H bins 06 to 08], 5H [1_0621 to 2_1344 (positions 56.40 to 98.42 cM) in 5H bins 03 to 06], and 6H [1_0799 to 1_0239 (positions 50.33 to 180.69 cM) in 6H bins 04 to 11] of the Bowman backcross-derived line BW489 (1).


Awns of lks6.q plants are about one half normal length compared to the control. Otherwise the plants appear fairly normal (3). Under greenhouse conditions plants of the Bowman backcross-derived line for lks6.q, BW489, had reduced plant vigor, slightly reduced seed set, and awns that were about 1/3 normal length (2). Based on phenotypic expression and chromosome segments retained, the lks6.q mutant is unlikely to be allelic at previously described short awn (lks) loci or the breviaristatum (ari) loci.

Origin of mutant:

A fast neutron induced mutant in Morex (CIho 15773) (3).

Mutational events:

lks6.q (FN329, GSHO 3674) in Morex (CIho 15773) (3).

Mutant used for description and seed stocks:

lks6.q (FN329, GSHO 3674) in Morex; lks6.q in Bowman (PI 483237)*3 (BW489, NGB 20717).
