BGS 530, Eceriferum-yq, cer-yq
Stock number: BGS 530
Locus name: Eceriferum-yq
Locus symbol: cer-yq
Previous nomenclature and gene symbolization:
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).
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).
Origin of mutant:
An ethyl methanesulfonate induced mutant in Kristina (NGB 14661, NGB 1500) (3).
cer-yq.1246 (NGB 112134, GSHO 1550) in Kristina (NGB 14661, NGB 1500) (4).
Mutant used for description and seed stocks:
cer-yq.1246 (NGB 112134, GSHO 1550) in Kristina; cer-yq.1246 in Bowman (PI 483237)*3 (GSHO 2221); cer-yq.1246 in Bowman*2 (BW148, NGB 20554).
