BGS 527, Eceriferum-yn, cer-yn

BGN  40:125
Stock number: BGS 527
Locus name: Eceriferum-yn
Locus symbol: cer-yn

Previous nomenclature and gene symbolization:



Monofactorial recessive (4).
Probably located in chromosome 1H (1); cer-yn.1112 is associated with SNP markers between 2_0479 to 2_0095 (positions 0.0 to 89.85 cM) in 1H bins 01 to 08 of the Bowman backcross-derived line BW145 and also with SNP markers between 2_1187 and 2_1338 (positions 51.62 and 74.97) in 2H bins 05 to 06 (1).


Surface wax coating on the spike, leaf sheath, and stem is reduced (wax code + + ++) (4). In the Bowman backcross-derived line, the wax coating is only slightly reduced, but nodes are glossy. Grain weight was slightly reduced in Bowman backcross-derived line BW145 and grain yield was 2/3 to 3/4 of normal (2).

Origin of mutant:

An ethylene imine induced mutant in Kristina (NGB 14661, NGB 1500) (3).

Mutational events:

cer-yn.1112 (NGB 112000, GSHO 1547) in Kristina (NGB 14661, NGB 1500) (4).

Mutant used for description and seed stocks:

cer-yn.1112 (NGB112000, GSHO 1547) in Kristina; cer-yn.1112 in Bowman (PI 483237)*2 (GSHO 2218); cer-yn.1112 in Bowman*4 (BW145, NGB 20551).
