BGS 616, Uniculme 3, cul3
Stock number: BGS 616
Locus name: Uniculme 3
Locus symbol: cul3
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (5).
Located in chromosome 3HL (1); cul3.c is associated with SNP markers 2_0023 to 2_0168 (positions 169.94 to 173.82 cM) in 3H bin 11 of the Bowman backcross-derived line BW207 (1), likely in 3H bin 11.

Description:
Plants have only one tiller, which is taller and thicker than those of normal sibs. Spikes are lax and malformed with extra lateral spikelets at some rachis nodes and none at others. The first basal rachis internode is sometimes curved (5). Seed set is very low in the Bowman backcross-derived line, which causes a problem with maintenance of the line (2).
)
Origin of mutant:
An X-ray induced mutant in Donaria (PI 161974) (5).
Mutational events:
cul3.c (Mut. 3170, DWS 1343, GSHO 2494) in Donaria (PI 161974) (3, 5); cul3.m (FN498, GSHO 3677) in Steptoe (CIho 15229) may be an allele based on phenotypic similarity (4).
Mutant used for description and seed stocks:
cul3.c (GSHO 2494) in Donaria; cul3.c in Bowman (PI 483237)*7 (BW207, NGB 22035).
