BGS 303, Variegated 3, var3
Stock number: BGS 303
Locus name: Variegated 3
Locus symbol: var3
Previous nomenclature and gene symbolization:
Variegated 3 = va3 (4).
Inheritance:
Monofactorial recessive (4).
Located in chromosome 5HL (4); var3.c is about 29.7 cM distal from the raw1 (smooth awn 1) locus (4); Karlsson was unable to confirm the presence of var3 in chromosome 5H (3); var3.c is associated with SNP markers 2_1421 to 1_0477 (positions 159.51 to 173.49 cM) in 5H bins 09 to 10 of the Bowman backcross-derived line BW888 (1).

Description:
Narrow white stripes appear on the foliage and stems, but they are less extensive than the white streak 7 (wst7) type of streaks (4). Expression of var3.c is poor in the Bowman backcross-derived line (2). Compared to Bowman, plants of the Bowman backcross-derived line for var3.c, BW888, had 2 to 4 fewer kernels per spike than Bowman. Kernels of BW888 weighed less than those of Bowman, 52 vs. 58 mg, and test weight was about 10% lower. Grain yields of BW888 were about half those of Bowman (2).

Origin of mutant:
An X-ray induced mutant in Montcalm (CIho 7149) (4).
Mutational events:
var3.c (Alb Acc 306, GSHO 1277) in Montcalm (CIho 7149) (4).
Mutant used for description and seed stocks:
var3.c (GSHO 1277) in Montcalm; var3.c in Bowman (PI 483237)*5 (GSHO 2143); var3.c in Bowman*7 (BW888, NGB 22321).
