BGS 529, Eceriferum-yp, cer-yp
Stock number: BGS 529
Locus name: Eceriferum-yp
Locus symbol: cer-yp
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (4).
Located in chromosome 5HS most likely (1); cer-yp.949 is associated with SNP markers 1_0974 to 2_0392 (positions 41.29 to 109.27 cM) in 5H bins 03 to 06 and with SNP markers 2_1398 to 2_0742 (positions 13.67 to 29.05 cM) in 3H bins 01 to 02 of the Bowman backcross-derived line BW147 (1).

Description:
Surface wax coating on the leaf blade is reduced (wax code ++ ++ +) (4). Leaf blades have a pale green color similar to that of some chlorina mutants (2). Compared to Bowman, the Bowman backcross-derived line for cer-yp.949, BW147, was 10 to 15% shorter and had 3 to 5 fewer kernels per spike. Kernels weighed about 10% less and grain yields averaged about 1/3 of those for Bowman (2).
