BGS 721, Breviaristatum-w, ari-w
Stock number: BGS 721
Locus name: Breviaristatum-w
Locus symbol: ari-w
Previous nomenclature and gene symbolization:
Breviaristatum-153 = ari-153 (3).
Monofactorial recessive (2).
Located in chromosome 7H (1); ari-w.153 is associated with SNP markers 1_0721 to 1_0563 (positions 82.82 to 154.35 cM) in 7H bins 06 to 09 of the Bowman backcross-derived line BW027 (1).
Awns of ari-w.153 plants about 1/2 normal length (3) and mature late (4). Compared to Bowman, plants of the Bowman backcross-derived line for ari-w.153, BW027, were slightly taller and had awns that were thin and 1/3 to 1/2 normal length. Kernels of BW027 were slightly longer and thinner than those of Bowman and weighted slightly more. Grain yields and test weights of BW027 were equal to or slightly higher than those of Bowman (2).
Origin of mutant:
An ethyl methanesulfonate induced mutant in Foma (NGB 14659, CIho 11333) (3, 4).
ari-w.153 (NGB 115962) in Foma (NGB 14659, CIho 11333) (4).
Mutant used for description and seed stocks:
ari-w.153 (NGB 115962) in Foma; ari-w.153 in Bowman (PI 483237)*6 (BW027, NGB 20435).
