BGS 531, Eceriferum-yr, cer-yr
Stock number: BGS 531
Locus name: Eceriferum-yr
Locus symbol: cer-yr
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (4).
Located in chromosome 5HL (1); cer-yr.492 is associated with SNP markers 1_0622 to 1_0477 (positions 158.46 to 173.49 cM) in 5H bins 09 to 10 of the Bowman backcross-derived line BW149 (1).

Description:
Surface wax coating on the spike appears greatly reduced or absent, and surface wax coating on the leaf sheath and stem is reduced (wax code -/+ + ++) (4). Nodes are glossy and appear to lack surface wax (2). Kernels of the Bowman backcross-derived line for cer-yr.492, BW149 were slightly smaller and lighter than those of Bowman. Except for surface waxes, BW149, and Bowman were agronomically and morphologically in other characters similar (2).
