BGS 530, Eceriferum-yq, cer-yq
Stock number: BGS 530
Locus name: Eceriferum-yq
Locus symbol: cer-yq
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (4).
Located in chromosome 5H probably (1); the Bowman backcross-derived line for cer-yq.1246, BW148, retained two large donor parent segments of chromosome 5H, one in each arm, based on SNP markers, and small segments in other chromosomes (1).

Description:
Surface wax coating on the leaf blade appears absent (wax code ++ ++ -) (4). In the Bowman backcross-derived line for cer-yq.1246, BW148, the wax coating is reduced only on upper leaf blades (wax code ++ ++ +) (2). The phenotype associated with the cer-yq.1246 was difficult to observe in progeny from crosses to Bowman; thus, BW148 represents only two crosses to Bowman (2).
