BGS 444, Eceriferum-ya, cer-ya
Stock number: BGS 444
Locus name: Eceriferum-ya
Locus symbol: cer-ya
Previous nomenclature and gene symbolization:
Monofactorial recessive (3).
Located in chromosome 3HS (1); cer-ya.180 is probably linked to the btr1 (non-brittle rachis 1) locus based on linkage drag (1).
Surface wax coating on the leaf blade appears absent (wax code ++ ++ -) (3). Leaves have a light green color that persists from the seedling stage until maturity. Heading and maturity are delayed in plants homozygous for the cer-ya.180 gene.
Origin of mutant:
A propane disulfonic acid diethyl ester induced mutant in Bonus (NGB 14657, PI 189763) (2).
cer-ya.180 (NGB 111066, GSHO 1534) in Bonus (NGB 14657, PI 189763) (3).
Mutant used for description and seed stocks:
cer-ya.180 (NGB 111066, GSHO 1534) in Bonus; cer-ya.180 in Bowman (PI 483237)*3; cer-ya.180 in Bowman*7 (BW132, NGB 20538).
