BGS 569, Erectoides-y, ert-y

BGN  48:166
Stock number: BGS 569
Locus name: Erectoides-y
Locus symbol: ert-y

Previous nomenclature and gene symbolization:

Erectoides-69 = ert-69 (2).


Monofactorial recessive (1).
Location is unknown.


Plants of ert-y.69 had slightly denser spikes than the parent with an average rachis internode length value of 2.8 mm. Culm length is about 5/6 of normal (2). The mutant phenotype was not observed in crosses to Bowman (1).

Origin of mutant:

A neutron induced mutant in Bonus (NGB 14657, PI 189763) (2, 3).

Mutational events:

ert-y.69 (NGB 112668, GSHO 499) in Bonus (NGB 14657, PI 189763) (2).

Mutant used for description and seed stocks:

ert-y.69 (NGB 112668, GSHO 499) in Bonus; ert-y.69 in Bowman (PI 483237, NGB 22812)*1 (BW328, NGB 22123).
