BGS 539, Eceriferum-xb, cer-xb
Stock number: BGS 539
Locus name: Eceriferum-xb
Locus symbol: cer-xb
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (2).
Located in chromosome 4H (1); cer-xb.943 is associated with SNP markers 1_0394 to 1_0531 (positions 107.44 to 116.68 cM) in 4H bin 07 of the Bowman backcross-derived line BW128 (1), in 4H bin 07.
Description:
Surface wax coating on the spike appears absent (wax code - ++ ++) (4). In the Bowman backcross-derived line for cer-xb.943, BW128, peduncles appeared to lack surface wax (2). Compared to Bowman, BW128 plants were slightly shorter and had slightly shorter rachis internodes. Kernels of BW128 were about 5% lighter and test weights were nearly 10% lower. Grain yields of BW128 were about 3/4 those for Bowman (2).
Origin of mutant:
An isopropyl methanesulfonate induced mutant in Bonus (NGB14657, PI 189763) (3).
Mutational events:
cer-xb.943 (NGB 111831, GSHO 1559) in Bonus (NGB14657, PI 189763), -xb.1166 (NGB 112054) in Kristina (NGB14661, NGB 1500) (4).
Mutant used for description and seed stocks:
cer-xb.943 (NGB 111831, GSHO 1559) in Bonus; cer-xb.943 in Bowman (PI 483237)*4 (GSHO 2228); cer-xb.943 in Bowman*6 (BW128, NGB 20534).
