BGS 435, Eceriferum-zr, cer-zr

BGN  44:155
Stock number: BGS 435
Locus name: Eceriferum-zr
Locus symbol: cer-zr

Previous nomenclature and gene symbolization:



Monofactorial recessive (4).
Located in chromosome 5HL (1); cer-zr.260 is associated with SNP markers 2_0134 to 1_1200 (positions 163.74 to 180.02 cM) in 5H bin 10 of the Bowman backcross-derived line BW173 (1), in 5H bin 10.


Surface wax coating on the spike appears reduced or absent (wax code +/ - ++ ++) (4). In the Bowman backcross-derived line for cer-zr.260, BW173, the wax coating appeared absent on the spike and nodes and may be reduced on stem and leaf sheath (wax code - +/++ ++) (2). Besides surface waxes, BW173 and Bowman were morphologically and agronomically for other traits similar (2).

Origin of mutant:

An ethylene imine induced mutant in Foma (NGB14659, CIho 11333) (4).

Mutational events:

cer-zr.260 (NGB 111147, GSHO 1525) in Foma (NGB14659, CIho 11333) (3, 4); cer-zr.528 (NGB 111416) in Foma (3).

Mutant used for description and seed stocks:

cer-zr.260 (NGB 111147, GSHO 1525) in Foma; cer-zr.260 in Bowman (PI 483237)*3 (GSHO 2203); cer-zr.260 in Bowman*6 (BW173, NGB 22005).
