BGS 434, Eceriferum-zq, cer-zq

BGN  48:146
Stock number: BGS 434
Locus name: Eceriferum-zq
Locus symbol: cer-zq

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (7).
Location is unknown. The one donor parent SNP marker retained in the Bowman backcross-derived line for cer-zq.248 (BW172) was not mapped (1).

Description:

Surface wax coating on the leaf blades appears absent, but only on the three upper leaf blades (wax code ++ ++ -) (7). Plants of the original stock remain as a vegetative tuft for a long time before heading (7). Plants of the Bowman backcross-derived line for cer-zq.248 (BW172) had thin, short culms, about 70% of normal. Comparing BW172 plants to Bowman plants, awns were 2/3 normal, leaf blades were shorter and narrower, and spikes had few kernels, 16 vs. 22. BW172 plants headed about 3 days later and were very susceptible to lodging at maturity. Kernels of BW172 were thinner, 3.6 vs. 3.9 mm, and about 25% lighter. Average grain yield was less than 50% of that for Bowman (2).

Origin of mutant:

A diethyl sulfate induced mutant in Foma (NGB 14657, CIho 11333) (7).

Mutational events:

cer-zq.248 (NGB 111135, GSHO 1524) in Foma (NGB 14659, CIho 11333) (3, 7); cer-zq.761 (NGB 111649) in Bonus (NGB 14657, PI 189763) (4); cer-zq.1343 (NGB 111231) in Bonus (3); cer-zq.1378 (NGB 112266) in Bonus (6).

Mutant used for description and seed stocks:

cer-zq.248 (GSHO 1524, NGB 111135) in Foma; cer-zq.248 in Bowman (PI 483237, NGB 22812)*5 (GSHO 2202); cer-zq.248 in Bowman*7 (BW172, NGB 22004).
