BGS 200, Breviaristatum-z, ari-z
Stock number: BGS 200
Locus name: Breviaristatum-z
Locus symbol: ari-z
Previous nomenclature and gene symbolization:
Breviaristatum-189 = ari-189 (3).
Inheritance:
Monofactorial recessive (2).
Located in chromosome 4HS (1, 2); ari-z.189 is associated with SNP markers 2_1228 to 2_1374 (positions 5.42 to 41.13 cM) in 4H bins 01 to 04 and a small segment from markers 2_0972 to 1_0015 (positions 156.09 to 160.38 cM) in 6H bin 10 of the Bowman backcross-derived line BW029 (1).
Description:
The ari-z.189 mutant showed awn abortion on several apical spikelets (3). In the original stock for ari-z.189, the auricles were purple (4). In the Bowman backcross-derived line for ari-z.189 (BW029), awns were about 3/4 normal length. Kernel sizes and shapes and grain yields for BW029 and Bowman were similar (2). A new locus symbol ari-z is suggested for mutant ari.189 because none of the other named breviaristatum (ari) or short awn (lks) loci are associated with the terminal region of the short arm of chromosome 4H.

Origin of mutant:
A propyl methanesulfonate induced mutant in Foma (NGB 14659, CIho 11333) (3, 4).
Mutational events:

Mutant used for description and seed stocks:
ari-z.189 (NGB 115999) in Foma; ari-z.189 in Bowman (PI 483237, NGB 22812)*4 (BW029, NGB 20437).
