BGS 574, Erectoides-ze, ert-ze

BGN  45:207
Stock number: BGS 574
Locus name: Erectoides-ze
Locus symbol: ert-ze

Previous nomenclature and gene symbolization:

Erectoides-105 = ert-105 (3).

Inheritance:

Monofactorial recessive (3).
Located probably in chromosome 5HS (1); ert-ze.105 is associated with SNP markers 1_0974 to 2_1244 (positions 41.99 to 91.0 cM) in 5H bins 2 to 5 and with SNP markers 2_1374 to 2_1122 (positions 192.0 to 198.33 cM) in 4H bin 5 of the Bowman backcross-derived line BW334 (1).

Description:

Spikes are semicompact, but other phenotypic traits appear normal (3). Compared to Bowman, plants of the backcross-derived line for ert-ze.105, BW334, headed 2 days later and were up to 20 cm shorter. The Bowman stocks for ert-ze.105 and ert-za.102 might have been mixed during the backcrossing process (2).

Origin of mutant:

A spontaneous mutant in Bonus (NGB 14657, PI 189763) (3).

Mutational events:

ert-ze.105 (NGB 112704, GSHO 505) in Bonus (NGB 14657, PI 189763) (3).

Mutant used for description and seed stocks:

ert-ze.105 (NGB 112704, GSHO 505) in Bonus; ert-ze.105 in Bowman (PI 483237)*5 (GSHO 2264); ert-ze.105 in Bowman*6 (BW334, NGB 22129).
