BGS 567, Erectoides-v, ert-v
Stock number: BGS 567
Locus name: Erectoides-v
Locus symbol: ert-v
Previous nomenclature and gene symbolization:
Erectoides-57 = ert-57 (3).
Inheritance:
Monofactorial recessive (3).
Located in chromosome 6H (1); ert-v.57 is associated with SNP markers 1_0061 to 1_1261 (positions 70.15 to 107.26 cM) in 6H bins 05 to 07 of the Bowman backcross-derived line BW326 (1).
Located in chromosome 6H (1); ert-v.57 is associated with SNP markers 1_0061 to 1_1261 (positions 70.15 to 107.26 cM) in 6H bins 05 to 07 of the Bowman backcross-derived line BW326 (1).
Description:
Spikes appear abnormal with irregular placement of kernels. Rachis internode length is reduced with average values from 1.7 to 3.1 mm. Plants are weak and semi-sterile, anthers are often whitish, and culm length is about 3/4 of normal (4). Phenotypically the ert-v.57 mutant could be classified as an opposite spikelet type. Plants of the Bowman backcross-derived line for ert-v.57, BW326, have relatively low vigor with grain yield about 1/3 those of Bowman. BW326 headed 3 days later than Bowman, was 15 to 20% shorter, and had 3 to 6 fewer kernels per spike. Rachis internode lengths averaged 3.2 vs. 4.6 mm for Bowman. Kernel weights for BW326 were 20 to 25% lower and test weights were very low (2).
