BGS 524, Eceriferum-yk, cer-yk
Stock number: BGS 524
Locus name: Eceriferum-yk
Locus symbol: cer-yk
Previous nomenclature and gene symbolization:
Monofactorial recessive (4).
Located in chromosome 7HL (1); cer-yk.627 is associated with SNP markers 2_0385 to 1_0861 (positions 152.29 to 183.9 cM) in 7H bins 09 to 11 of the Bowman backcross-derived line BW142 (1).
Surface wax coating on the spike, leaf sheath, and stem appears reduced (wax code + + ++) (4). The original stock has narrow leaves, a lax spike, and extra wax coating on the kernels. Plants of the Bowman backcross-derived line BW142 seemed to lack surface wax on the nodes (glossy node) (2). Compared to Bowman, plants of the Bowman backcross-derived line for cer-yk.627, BW142, are 10 to 15% shorter and rachis internodes were slightly longer. BW142 had slightly narrower leaf blades and kernels. Kernel weights were 10 to 15% less and grain yields were 30 to 50% lower than those for Bowman (2).
Origin of mutant:
A neutron induced mutant in Bonus ( NGB 14657, PI 189763) (3).
cer-yk.627 (NGB 111515, GSHO 1544) in Bonus (NGB 14657, PI 189763) (4).
Mutant used for description and seed stocks:
cer-yk.627 (NGB 111515, GSHO 1544) in Bonus; cer-yk.627 in Bowman (PI 483237)*4 (GSHO 2215); cer-yk.627 in Bowman*7 (BW142, NGB 20548).
