BGS 238, Breviaristatum-t, ari-t

BGN  47:104
Stock number: BGS 238
Locus name: Breviaristatum-t
Locus symbol: ari-t

Previous nomenclature and gene symbolization:

Breviaristatum-25 = ari-25 (3).

Inheritance:

Monofactorial recessive (2, 4).
Located in chromosome 1H (1); ari-t.25 is associated with SNP markers between 1_0744 to 1_1326 (positions 39.84 to 82.35 cM) in 1H of the Bowman backcross-derived line BW032 (1), in 1H bins 05 to 08).

Description:

The awns of ari-t plants are 2/3 of normal length and slightly curly. Peduncles are coiled and less than half normal length, and plants are 1/2 to 2/3 normal height (4, 5). In the Bowman backcross-derived line for ari-t.25, BW032, leaf blades were shorter and narrower than those of Bowman. Kernels of BW032 were shorter and narrower, seed weights were about 20% lower, and seed yields were about 1/4 of normal (2). A new locus name was assigned based on the unique phenotype and lack of other breviaristatum mutants located in 1H.

Origin of mutant:

An ethylene oxide induced mutant in Bonus (NGB 14657, PI 189763) (4, 5).

Mutational events:

ari-t.25 (NGB 115873) in Bonus (NGB 14657, PI 189763) (5).

Mutant used for description and seed stocks:

ari-t.25 (NGB 115873) in Bonus; ari-t.25 in Bowman (PI 483237)*5 (BW032, NGB 20440).
