BGS 558, Breviaristatum-q, ari-q
Stock number: BGS 558
Locus name: Breviaristatum-q
Locus symbol: ari-q
Previous nomenclature and gene symbolization:
Breviaristatum-271 = ari-271 (3).
Inheritance:
Monofactorial recessive (3).
Location in chromosome 4H (1); ari-q.280 is associated with SNP markers 2_0289 to 1_0588 (positions 69.62 to 130.65 cM) in 4H bins 05 to 09 of the Bowman backcrossed-derived line BW055 (1).
Location in chromosome 4H (1); ari-q.280 is associated with SNP markers 2_0289 to 1_0588 (positions 69.62 to 130.65 cM) in 4H bins 05 to 09 of the Bowman backcrossed-derived line BW055 (1).
Description:
The spike is short with irregular placement of spikelets. Awns are about 3/4 normal length. Lateral spikelets are missing from a few basal rachis nodes and two awns occur occasionally on the terminal spikelet (3). Compared to Bowman, plants of the Bowman backcross-derived line for ari-q.280, BW055, headed 3 to 4 days later, were 15 to 20% shorter, and had 2 to 4 fewer kernels per spike. Kernels of BW055 weighed less, 52 vs. 59 mg, than those of Bowman, the grain yields of BW055 were about 25% lower (2).
