BGS 538, Eceriferum-xa, cer-xa
Stock number: BGS 538
Locus name: Eceriferum-xa
Locus symbol: cer-xa
Previous nomenclature and gene symbolization:
Monofactorial recessive (4).
Located in chromosomes 2HL, 4H, or 5HL (1); cer-xa.585 is associated with SNP markers 1_0786 to 2_0182 (positions 133.59 to 185.53 cM) in 2H bins 09 to 12, with SNP markers 1_0221 to 1_0829 (positions 29.67 to 107.76 cM) in 4H bins 02 to 07, and with SNP markers 1_0845 to 1_0869 (positions 217.82 to 264.33 cM) in 5H bins 11 to 13 of the Bowman backcross-derived line BW127 (1).
Surface wax coating on the leaf blade appears absent only on upper leaves (wax code ++ ++ -) (4). The Bowman backcross-derived line for cer-xa.585, BW127, appeared to have more surface on the leaf blades (wax code ++ ++ +) than the original mutant. Plants of line BW127 and Bowman were similar in other agronomic and morphological traits, except BW127 had slightly lighter kernels and yielded slightly more grain (2).
Origin of mutant:
A gamma-ray induced mutant in Foma (NGB 14659, CIho 11333) (3).
cer-xa.585 (NGB 111473, GSHO 1558) in Foma (NGB 14659, CIho 11333), -xa.838 (NGB 111726) in Bonus (NGB14657, PI 189763), -xa.1113 (NGB 112001) in Kristina (NGB 14661, NGB 1500) (4).
Mutant used for description and seed stocks:
cer-xa.585 (NGB 111473, GSHO 1558) in Foma; cer-xa.585 in Bowman (PI 483237)*2 (GSHO 2227); cer-xa.585 in Bowman*3 (BW127, NGB 20533).
