BGN  40:136 Export to PDF
Stock number: BGS 568
Locus name: Erectoides-x
Locus symbol: ert-x

Previous nomenclature and gene symbolization:

Erectoides-58 = ert-58 (3).

Inheritance:

Monofactorial recessive (3).
Location in chromosomes 1H or 7H (1); ert-x.58 is associated with SNP markers 2_0617 to 2_1126 (positions 50.96 to 110.10 cM) in 1H bins 05 to 10 and markers 1_1028 to 2_0230 (positions 97.66 to 118.80 cM) in 7H bin 07 of the Bowman backcrossed-derived line BW327 (1).

Description:

Spikes are semi-compact with a rachis internode length value of 2.7 mm. Culm length is about 3/4 of normal (4). Compared to Bowman, the backcross-derived line BW327 had internode lengths of 3.5 vs. 4.6 mm, awn lengths were 7 vs. 11 cm, and plants headed 3 to 4 days later. Other morphological traits and yields of BW327 were similar to those of Bowman (2).

Origin of mutant:

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

Mutational events:

ert-x.58 (NGB 112657, GSHO 498) in Bonus (NGB 14657, PI 189763) (3, 4).

Mutant used for description and seed stocks:

ert-x.58 (NGB 112657, GSHO 498) in Bonus; ert-x.58 in Bowman (PI 483237)*5 (GSHO 2259); ert-x.58 in Bowman*7 (BW327, NGB 22122).
