BGS 573, Erectoides-zc, ert-zc
Stock number: BGS 573
Locus name: Erectoides-zc
Locus symbol: ert-zc
Previous nomenclature and gene symbolization:
Erectoides-149 = ert-149 (3).
Monofactorial recessive (3).
Located probably in chromosome 7HS (1); ert-zc.149 is associated with SNP markers 2_0722 to 1_0056 (positions 23.45 to 51.93 cM) in 7H bins 2 to 4 and with SNP markers 1_1497 to 2_0545 (positions 237.41 to 244.39 cM) in 5H bin 12 of the Bowman backcross-derived line BW332 (1).
Spikes are semicompact and plants are semidwarf (3/4 normal height). The basal rachis internode is slightly elongated (3). Compared to Bowman, plants of the backcross-derived line for ert-zc.149, BW332, were about 10 cm shorter, peduncles were 4 to 8 cm shorter, and rachis internodes were 10 to 20% shorter. BW332 plants headed 2 to 3 days later than Bowman plants. Kernels of BW332 weighed 5 to 10% less than those of Bowman, but both lines had similar grain yields (2).
Origin of mutant:
An ethylene oxide induced mutant in Bonus (NGB 14657, PI 189763) (3).
ert-zc.149 (NGB 112748, GSHO 503) in Bonus (NGB 14657, PI 189763) (3).
Mutant used for description and seed stocks:
ert-zc.149 (NGB 112748, GSHO 503) in Bonus; ert-zc.149 in Bowman (PI 483237)*3 (GSHO 2263); ert-zc.149 in Bowman*4 (BW332, NGB 22127).
