BGS 528, Eceriferum-yo, cer-yo

BGN  44:168
Stock number: BGS 528
Locus name: Eceriferum-yo
Locus symbol: cer-yo

Previous nomenclature and gene symbolization:



Monofactorial recessive (3).
Located in chromosome 4HS most likely (1); the largest donor parent chromosomal segment associated with cer-yo.647 has SNP markers 2_0145 to 2_0210 (positions 26.58 to 38.91 cM) in 4H bins 02 to 04 of the Bowman backcross-derived line BW146 (1).


Surface wax coating on the leaf blade is reduced (wax code ++ ++ +) (4). The original stock in Bonus exhibited a high level of sterility. Seedlings of the original stock and the Bowman backcross-derived line have slightly pale green color (2). Bowman and the Bowman backcross-derived line for cer-yo.647, BW146, were agronomically similar except the BW146 kernels were slightly lighter (2).

Origin of mutant:

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

Mutational events:

cer-yo.647 (NGB 111535, GSHO 1548) in Bonus (NGB 14657, PI 189763) (4).

Mutant used for description and seed stocks:

cer-yo.647 (NGB 111535, GSHO 1548) in Bonus; cer-yo.647 in Bowman (PI 483237)*3 (GSHO 2219); cer-yo.647 in Bowman*4 (BW146, NGB 20552).
