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).
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).
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).
Origin of mutant:
A neutron induced mutant in Bonus (NGB 14657, PI 189763) (3).
ert-v.57 (NGB 112656, GSHO 497) in Bonus (NGB 14657, PI 189763) (3); ert-v.172 (NGB 112772) in Bonus, -v.313 in Foma (NGB 14659, CIho 11333) (4).
Mutant used for description and seed stocks:
ert-v.57 (NGB 112656, GSHO 497) in Bonus; ert-v.57 in Bowman (PI 483237)*6 (GSHO 2258); ert-v.57 in Bowman*7 (BW326, NGB 22121).
