BGS 535, Eceriferum-yx, cer-yx
Stock number: BGS 535
Locus name: Eceriferum-yx
Locus symbol: cer-yx
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (4).
Located in chromosomes 1HL, 3HL, or 5H (1); cer-yx.421 is associated with SNP markers from 1_1198 to 2_0392 (positions 73.70 to 109.27 cM) and from 1_0783 to 1_1441 (positions 208.43 to 231.75 cM) in 5H bins 04 to 06 and 11 to 12, respectively, markers from 1_1241 to 2_0659 (positions 108.07 to 141.21 cM) in 3H bins 07 to 09, and markers from 2_0121 to 2_0921 (positions 112.25 to 155.95 cM) in 1H bins 10 to 12 of the Bowman backcross-derived line BW153 (1).

Description:
Surface wax coating on the spike, the leaf sheath, and stem appears reduced (wax code + + ++) (4). Plants of the Bowman backcross-derived line for cer-yx.421 (BW153) were slightly shorter than Bowman plants, and kernels were 10 to 15% lighter. Grain yields were similar (2).
