BGS 405, Eceriferum-k, cer-k
Stock number: BGS 405
Locus name: Eceriferum-k
Locus symbol: cer-k
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (4).
Located in chromosome 4HL (1); cer-k.39 is associated with SNP markers 1_0387 to 1_1019 (positions 179.78 to 183.54 cM) in 4H bins 12 to 13 of the Bowman backcross-derived line BW115 (1). cer-k.39 is previously located in 7HS, based on a linkage drag association with the ant1 (anthocyanin-less 1) locus (3).
Description:
Surface wax coating on the spike is slightly reduced compared to the parent (wax code + ++ ++) (4). In the Bowman backcross-derived line for cer-k.39, BW115, leaf blades and kernels appeared slightly thinner compared to those of Bowman (2). BW115 plants headed 5 to 10 days later than Bowman and were slightly shorter, but they had up to 5 more kernels per spike. Kernel weights of BW115 were 10 to 15% lower and grain yields were about 75% of the Bowman yields (2).
Origin of mutant:
An X-ray induced mutant in Bonus (NGB 14657, PI 189763) (4).
Mutational events:
cer-k.39 (NGB 110923, GSHO 432) in Bonus (NGB 14657, PI 189763) (4, 5).
Mutant used for description and seed stocks:
cer-k.39 (NGB 110923, GSHO 432) in Bonus; cer-k.39 in Bowman (PI 483237)*6 (GSHO 1837); cer-k.39 in Bowman*7 (BW115, NGB 20521).
