BGS 449, Eceriferum-yf, cer-yf
Stock number: BGS 449
Locus name: Eceriferum-yf
Locus symbol: cer-yf
Previous nomenclature and gene symbolization:
Monofactorial recessive (4).
Located in chromosome 7H (1); cer-yf.652 is associated with SNP markers 1_0394 to 1_0531 (positions 107.44 to 116.68 cM) in 7H bin 07 of the Bowman backcross-derived line BW137 (1), near the centromere in 7H bin 07.
Surface wax coating on the leaf blade is reduced (wax code ++ ++ +) (4). Plants of the Bowman backcross-derived line for cer-yf.652, BW137, had slightly pale green leaf blades, headed 3 to 5 days later, and had 2 to 5 more kernels per spike (2). BW137 plants were slightly shorter than Bowman. Kernels of BW137 were 10 to 20% lighter, and grain yields were 1/2 to 2/3 of those for Bowman (2).
Origin of mutant:
A neutron induced mutant in Bonus (NGB14657, PI 189763) (3).
cer-yf.652 (NGB 111540, GSHO 1539), -yf.804 (NGB 111692) in Bonus (NGB 14657, PI 189763) (4).
Mutant used for description and seed stocks:
cer-yf.652 (NGB 111540, GSHO 1539) in Bonus; cer-yf.652 in Bowman (PI 483237)*3 (GSHO 2212); cer-yf.652 in Bowman*5 (BW137, NGB 20543).
