BGS 409, Eceriferum-o, cer-o
Stock number: BGS 409
Locus name: Eceriferum-o
Locus symbol: cer-o
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (3).
Located in chromosome 1HL (1); cer-o.28 is associated with SNP markers 2_0229 to 1_0006 (positions 106.61 to 110.10 cM) in 1H bin 10 of the Bowman backcrossed-derived line BW119 (1), in 1H bin 10.

Description:
Surface wax coating on the spike appears absent or reduced (wax code -/+ ++ ++) (3). All cer-o mutants have pointed lateral spikelets and semi-sterility (50 to 75% seed set). Mutant segregates in the Bowman backcross-derived progenies were about 3/4 of normal height and had spikes with about 20% fewer fertile rachis nodes. Plants of Bowman backcross-derived line BW119 headed about two days later than Bowman and were about 15% shorter. Kernel weights were 10-15% lower and grain yields were about half those of Bowman (2).
