BGS 436, Eceriferum-zs, cer-zs

BGN  44:156
Stock number: BGS 436
Locus name: Eceriferum-zs
Locus symbol: cer-zs

Previous nomenclature and gene symbolization:



Monofactorial recessive (4).
Location is unknown; large chromosomal segments from the donor parent were retained in chromosomes 2H, 3H, and 5H in the Bowman backcross-derived line for cer-zs.467, BW174 (1).


Surface wax coating on the spike is reduced (wax code + ++ ++), maturity is delayed, and vigor is somewhat reduced (4). Compared to Bowman, plants of the Bowman backcross-derived line for cer-zs.467, BW174, headed about three days later and had 2 to 5 more kernels per spike. Kernel weights for BW174 averaged 10% less than those for Bowman. The grain yields for BW174 were about 2/3 of those for Bowman (2).

Origin of mutant:

An ethyl methanesulfonate induced mutant in Foma (NGB 14659, CIho 11333) (3).

Mutational events:

cer-zs.467 (NGB 111355, GSHO 1526), -zs.474 (NGB 111362), -zs.475 (NGB 111363) in Foma (CIho 11333, NGB 14659) (4); cer-zs.594 (NGB 111482) in Foma (5).

Mutant used for description and seed stocks:

cer-zs.467 (NGB 111355, GSHO 1526) in Foma; cer-zs.467 in Bowman (PI 483237)*3 (GSHO 2204, BW174, NGB 22006).
