Stock number: BGS 555
Locus name: Breviaristatum-n
Locus symbol: ari-n

Previous nomenclature and gene symbolization:

Breviaristatum-45 = ari-45 (3).

Inheritance:

Monofactorial recessive (3).
Located in chromosome 7H (1); ari-n.45 is associated with SNP markers 1_0721 to 1_0700 (positions 82.82 to 144.00 cM) in 7H bins 06 to 08 of the Bowman backcrossed-derived line BW052 (1).

Description:

Awns are 3/4 normal length and arise at an oblique angle, and they are drastically shortened towards the top of the spike (3). Plant height is normal, but spikes are short due to a reduced number of rachis internodes and apical abortion (3). Plants of the Bowman backcross-derived line for ari-n.45, BW052, varied in height over environments from 20% shorter to equal to Bowman. Awns extended in specific environments from 2 to 6 cm beyond the tip of the spike while those of Bowman extended about 11 cm. The kernels of BW052 were thinner, 3.5 vs.3.8 mm, than those of Bowman, slightly shorter and about 25% less, 4.4 vs. 5.9 mg. Grain yields of BW052 varied from 2/3 to 3/4 those of Bowman (2).

Origin of mutant:

A gamma-ray induced mutant in Bonus (NGB 14657, PI 189763) (3).
