BGS 257, Smooth awn 5, raw5
Stock number: BGS 257
Locus name: Smooth awn 5
Locus symbol: raw5
Previous nomenclature and gene symbolization:
Smooth awn e = r,,e (3).
Smooth awn 2 = r2 (3).
Smooth awn 5 = r5 (4).
Smooth awn 2 = r2 (3).
Smooth awn 5 = r5 (4).
Inheritance:
Monofactorial recessive (3).
Located in chromosome 6HL (3, 4); raw5.e is over 31.5 cM distal from the rob1 (orange lemma 1) locus (3); raw5.e is associated with SNP markers 2_0651 to 1_0377 (positions 89.76 to 91.91 cM) in 6H bin 06 of the Bowman backcross-derived line BW664 (1), likely in 6H bin 06.

Description:
Plants have fewer stigma hairs and seed set is reduced, but more barbs developed on the central vein of the awn than in raw1.a plants (4). The Bowman backcross-derived line contains both of raw1.a and raw5.e genes for smooth awn. It has very smooth awns and very few stigma hairs, and seed set is often less than 10%. Compared to Bowman, plants of the Bowman backcross-derived line for raw5.e, BW664, were about 15% shorter. Selfed seed set was very low in field plots and rare in the greenhouse (2).

Origin of mutant:
An ethyl methanesulfonate induced mutant in Akashinriki (OUJ659, PI 467400) (3).
Mutational events:
raw5.e (OUM195, GSHO 771) in Akashinriki (OUJ659, PI 467400) (3, 4); raw5.e plus rob1.a in GSHO 785 (from T. Konishi).
Mutant used for description and seed stocks:
raw5.e (GSHO 771) in Akashinriki; raw5.e in Bowman (PI 483237)*6 (GSHO 2085, BW664, NGB 22472).
