BGS 572, Erectoides-zb, ert-zb
Stock number: BGS 572
Locus name: Erectoides-zb
Locus symbol: ert-zb
Previous nomenclature and gene symbolization:
Erectoides-132 = ert-132 (3).
Monofactorial recessive (3).
Located in chromosome 7HL (1); ert-zb.132 is associated with SNP markers 2_0824 to 2_1363 (positions 146.97 to 198.70 cM) in 7H bins 9 to 12 of the Bowman backcross-derived line BW331 (1).
Plants are 3/4 normal height and spikes tend to emerge prematurely (3). Compared to Bowman, plants of the backcross-derived line for ert-zb.132, BW331, headed 2 to 4 days later and were 15 to 20% shorter. Peduncles were 2/3 normal length and rachis internodes were about 10% shorter. Kernel weights for BW331 averaged 15% less than those of Bowman, 5.1 vs.5.8 mg, and grain yields were about 25% lower (2).
Origin of mutant:
A diepoxybutane induced mutant in Bonus (NGB 14657, PI 189763) (3).
ert-zb.132 (NGB 112731, GSHO 502) in Bonus (NGB 14657, PI 189763) (3).
Mutant used for description and seed stocks:
ert-zb.132 (NGB 112731, GSHO 502) in Bonus; ert-zb.132 in Bowman (PI 483237)*5 (GSHO 2262, BW331, NGB 22126).
