BGS 534, Eceriferum-yu, cer-yu
Stock number: BGS 534
Locus name: Eceriferum-yu
Locus symbol: cer-yu
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (4).
Located probably in chromosome 1H (1); cer-yu.159 is associated in centromeric region with SNP markers between 1_0275 to 2_1126 (positions 63.72 to 110.10 cM) in 1H bins 06 to 10 of the Bowman backcross-derived line BW152 (1), but small donor parent segments are also retained in 3HL (SNP markers 2_0523 to 1_0754 at positions 173.82 to 190.87) and in 4HL (SNP markers 2_0765 to 2_0384 at positions127.80 to 133.98) of the Bowman backcross-derived line BW152 (1).

Description:
Surface wax coating on the leaf blade appears absent only on upper leaves (wax code
++ ++ -) (3). Mutant plants have slightly coiled awns. The Bowman backcross-derived line for cer-yu.159 (BS152) is weak in the field and has short leaves, but these traits were not as obvious in greenhouse grown plants. The peduncles of BW152 were about 2/3 of normal length, and rachis internodes were slightly shorter. Kernels of BW152 were slightly shorter and thinner, and their weights were about 1/4 lower. Grain yields of BW152 were less than half those of Bowman (2).
