BGS 446, Eceriferum-yc, cer-yc
Stock number: BGS 446
Locus name: Eceriferum-yc
Locus symbol: cer-yc
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (4).
Location in chromosome 6H or 7HS (1); cer-yc.135 is associated with SNP markers 1_0061 to 1_1261 (positions 70.15 to 107.26 cM) in 6H bins 05 to 07 and SNP markers 2_1419 to 1_0838 (positions 0.0 to 49.53 cM) in 7H bins 01 to 04 of the Bowman backcross-derived line BW134 (2);

Description:
Surface wax coating on the spike appears absent (wax code - ++ ++) (3). Surface wax on the leaf sheath appears reduced in the Bowman backcross-derived line (wax code - + ++). The long-chain n-alkanes on the spike were reduced without greatly altering the chain-length distributions of the minor hydrocarbons (7). Compared to Bowman, the Bowman backcross-derived line for cer-yc.135, BW134, had kernels that were slightly smaller with weights about 10% less. Grain yields for BW134 were about 3/4 those for Bowman. Other morphological differs from Bowman were not observed (2).
