BGS 442, Eceriferum-zy, cer-zy

BGN  40:116
Stock number: BGS 442
Locus name: Eceriferum-zy
Locus symbol: cer-zy

Previous nomenclature and gene symbolization:



Monofactorial recessive (4).
Located in chromosome 1HS (1); cer-zy.118 is associated with SNP markers 2_0479 to 2_0502 (positions 0.0 to 3.18 cM) in 1H bin 01 of the Bowman backcross-derived line BW180 (1), in 1H bin 01.


Surface wax coating on the leaf blade appears slightly reduced on the upper three leaves (wax code ++ ++ +) (4). Seedling leaves have a slightly yellow green color similar to that found in some chlorina mutants. Other morphological traits and plant vigor appeared normal in Bowman backcross-derived line BW180 (2).

Origin of mutant:

An X-ray induced mutant in Bonus (NGB 14657, PI 189763) (3).

Mutational events:

cer-zy.118 (NGB 111103, GSHO 1532) in Bonus (NGB 14657, PI 189763) (4); cer-zy.136 (NGB 111021) in Bonus (5).

Mutant used for description and seed stocks:

cer-zy.118 (NGB 111003, GSHO 1532) in Bonus; cer-zy.118 in Bowman (PI 483237)*5 (BW180, NGB 22012).
