BGS 560, Erectoides-f, ert-f
Stock number: BGS 560
Locus name: Erectoides-f
Locus symbol: ert-f
Previous nomenclature and gene symbolization:
Erectoides-18 = ert-18 (3).
Inheritance:
Monofactorial recessive, but some partial dominance is expressed (3, 6).
Located in chromosome 1H (1); ert-f.18 is associated with SNP markers 2_0617 to 2_1361 (positions 50.96 to 82.35 cM) in 1H bins 05 to 08 of the Bowman backcross-derived line BW308 (1).
Located in chromosome 1H (1); ert-f.18 is associated with SNP markers 2_0617 to 2_1361 (positions 50.96 to 82.35 cM) in 1H bins 05 to 08 of the Bowman backcross-derived line BW308 (1).
Description:
Spikes are semicompact with average rachis internode length values from 2.2 to 2.6 mm. Culm length is about 5/6 of normal (6). Sterile lateral spikelets of ert-f plants are larger than those of normal sibs, but apices are rounded. Plants of the Bowman backcross-derived line gfor ertt-f.18 (BW308) had an average rachis internode length of 3.4 vs. 4.4 mm for Bowman. Kernels of BW308 were slightly wider and shorter than those of Bowman, and grain yields were slightly lower (2).
