BGS 437, Eceriferum-zt, cer-zt

BGN  44:157
Stock number: BGS 437
Locus name: Eceriferum-zt
Locus symbol: cer-zt

Previous nomenclature and gene symbolization:



Monofactorial recessive (5).
Location in chromosome 2HS (1); cer-zt.389 is about 16.8 distal from SSR marker Bmac0134 in 2H bin 01 (1); cer-zt.389 is associated with SNP markers 1_0326 to 1_0399 (positions 16.91 to 66.78 cM) in 2H bins 02 to 05 of the Bowman backcross-derived line BW175 (2), likely in 2H bin 02.


Surface wax coating on the spike appears slightly reduced (wax code + ++ ++) (5). The reduction in the surface wax seemed greater in plants selected from backcrosses to Bowman (wax code +/- ++ ++) (3). Except for the difference in surface waxes, plants of the Bowman backcross-derived line for cer-zt.389, BW175, and Bowman were similar (3).

Origin of mutant:

An ethyl methanesulfonate and neutron induced mutant in Foma (NGB 14659, CIho 11333) (4).

Mutational events:

cer-zt.389 (NGB 111276, GSHO 1527), -zt.479 (NGB 111367) in Foma (NGB 14659, CIho 11333) (4).

Mutant used for description and seed stocks:

cer-zt.389 (NGB 111276, GSHO 1527) in Foma; cer-zt.389 in Bowman (PI 483237)*2 (GSHO 2205); cer-zt.389 in Bowman*5 (BW175, NGB 22007).
