BGS 557, Breviaristatum-p, ari-p

BGN  46:120
Stock number: BGS 557
Locus name: Breviaristatum-p
Locus symbol: ari-p

Previous nomenclature and gene symbolization:

Breviaristatum-27 = ari-27 (3).


Monofactorial recessive (3).
Location is unknown, no SNP markers were retained in the Bowman backcross-derived line BW054 for ari-p.27 (1); the late heading trait observed in early backcrosses to Bowman might have reflected a repulsion linkage to the Early maturity 6 (Eam6.h) gene of Bowman (2).


Awns are about 3/4 normal length, and sterile spikelets occur at random in the original stocks (3). Initially during backcrossing to Bowman, short awned plants headed later than Bowman. In the Bowman backcross-derived line for ari-p.27, BW054, plants head about one day later than Bowman and have awn length from the tip of the spike of 6 vs. 11 cm. No other morphological differences were observed (2).

Origin of mutant:

An X-ray induced mutant in Bonus (NGB 14657, PI 189763) (4).

Mutational events:

ari-p.27 (NGB 115875, GSHO 1664) in Bonus (NGB 14657, PI 189763) (4); ari-p.108 (NGB 115928), -p.172 (NGB 115982), -p.208 (NGB 116016), -p.209 (NGB 116017), -p.223 (NGB 116032) in Foma (NGB 14659, CIho 11333) (3); ari-p.278 (NGB 116091) in Kristina (NGB 14661, NGB 1500) (4).

Mutant used for description and seed stocks:
