BGN  48:165
Stock number: BGS 565
Locus name: Erectoides-s
Locus symbol: ert-s

Previous nomenclature and gene symbolization:

Erectoides-50 = ert-50 (3).


Monofactorial recessive (3).
Located likely in chromosome 7H (1); ert-s.50 is associated with SNP markers from 2_0249 to 1_1521 (positions 69.65 to 174.96 cM) in 7H bins 05 to 10 and with SNP markers in small regions from 2_0715 to 2_0994 (positions 213.08 to 233.44 cM) in 2H bins 13 to 14 and from 1_1411 to 1_0283 (positions ≈249.0 to 25.13 cM) in 3H bins 15 to 16 of the Bowman backcross-derived line BW323 (1).


The rachis internode length of ert-s.50 spikes was reduced slightly to about 3.0 mm, and culm length was about 5/6 of normal (4). The ert-s.50 mutant was a very late segregate from the F2 progeny of the cross to Bowman. However, the Bowman backcross-derived line for ert-s.50 (BW323) only headed slightly later and had slightly shorter awns (2).

Origin of mutant:

An X-ray induced mutant in Bonus (NGB 14657, PI 189763) (3).

Mutational events:

ert-s.50 (NGB 112649, GSHO 493) in Bonus (NGB 14657, PI 189763) (3, 4).

Mutant used for description and seed stocks:

ert-s.50 (NGB 112649, GSHO 493) in Bonus; ert-s.50 in Bowman (PI 483237, NGB 22812)*2 (GSHO 2256); ert-s.50 in Bowman*3 (BW323, NGB 22118).
