BGS 23, Winding dwarf 1, wnd1
Stock number: BGS 23
Locus name: Winding dwarf 1
Locus symbol: wnd1
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (1).
Located in chromosome 4HL (1); wnd1.a is associated with SNP markers 1_1398 to 2_0384 (positions 127.80 to 133.98 cM) in 4H bins 09 to 10 of the Bowman backcross-derived line BW906 (1). Previously located in chromosome 7HS (3); over 25.4 cM distal from the dsp1 (dense spike 1) locus (3).

Description:
Plants are semidwarf (15 cm shorter than the original cultivar) and have a pronounced coiling or winding of the upper portion of peduncle (3). The original stock for the wnd1.a gene also contained the dense spike (dsp1.a) gene, but the Bowman backcross-derived line, BW906, does not (2). Only a slight and inconsistent reduction in plant height was observed in BW906 compared to Bowman. However, the BW906 plants had a distinct coiling of the upper portion of the peduncle. No other morphological differences compared to Bowman were observed (2).
