BGS 441, Eceriferum-zx, cer-zx

BGN  46:111
Stock number: BGS 441
Locus name: Eceriferum-zx
Locus symbol: cer-zx

Previous nomenclature and gene symbolization:



Monofactorial recessive (4).
Located in chromosome 3H (1); cer-zx.100 is associated largely with SNP markers 1_0728 to 2_0523 (positions 96.85 to 173.82 cM) in 3H bins 06 to 11 of the Bowman backcross-derived line BW179 (1).


Surface wax coating on the spike, leaf sheath, and stem appears reduced (wax code + + ++) (4). The noted difference between the Bowman backcross-derived line for cer-zx.100, BW179, were the reduction in surface waxes on the spike and leaf sheath and the strong presence of wax on the nodes (2)..

Origin of mutant:

An ethyl methanesulfonate induced mutant in Bonus (NGB14657, PI 189763) (3).

Mutational events:

cer-zx.100 (NGB 110984, GSHO 1531) in Bonus (NGB14657, PI 189763) (4).

Mutant used for description and seed stocks:

cer-zx.100 (NGB 110984, GSHO 1531) in Bonus; cer-zx.100 in Bowman (PI 483237)*2 (GSHO 2209); cer-zx.100 in Bowman*5 (BW179, NGB 22011).
