BGS 538, Eceriferum-xa, cer-xa
Stock number: BGS 538
Locus name: Eceriferum-xa
Locus symbol: cer-xa
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (4).
Located in chromosomes 2HL, 4H, or 5HL (1); cer-xa.585 is associated with SNP markers 1_0786 to 2_0182 (positions 133.59 to 185.53 cM) in 2H bins 09 to 12, with SNP markers 1_0221 to 1_0829 (positions 29.67 to 107.76 cM) in 4H bins 02 to 07, and with SNP markers 1_0845 to 1_0869 (positions 217.82 to 264.33 cM) in 5H bins 11 to 13 of the Bowman backcross-derived line BW127 (1).

Description:
Surface wax coating on the leaf blade appears absent only on upper leaves (wax code ++ ++ -) (4). The Bowman backcross-derived line for cer-xa.585, BW127, appeared to have more surface on the leaf blades (wax code ++ ++ +) than the original mutant. Plants of line BW127 and Bowman were similar in other agronomic and morphological traits, except BW127 had slightly lighter kernels and yielded slightly more grain (2).
