BGS 570, Erectoides-z, ert-z
Stock number: BGS 570
Locus name: Erectoides-z
Locus symbol: ert-z
Previous nomenclature and gene symbolization:
Erectoides-71 = ert-71 (3).
Inheritance:
Monofactorial recessive (3).
Located likely in chromosome 5H (1); ert-z.71 is associated with SNP markers from 2_1253 to 2_1341 (positions 65.06 to 98.42 cM) in 5H bins 04 to 06 of the Bowman backcross-derived line BW329 (1); also retained in BW329 were small groups of parental markers in 1HL from 2_1446 to 2_1373 (positions 136.36 to 141.35 cM) in 1H bin 11, and 7HL 1_1243 to 1_0861 (positions 167.56 to 183.90 cM) in 7H bins 10 to 11 (1).

Description:
Plants of the ert-z.71 mutant had slightly denser spikes than their parent; with a rachis internode length value of 2.8 mm. Culm length was about 3/4 of normal (4). In the Bowman backcross-derived line for ert-z.71 (BW329), variability in the rachis internode length observed, and average internode lengths were 3.8 vs. 4.5 mm for Bowman. BW329 plants were 10 to 15% shorter and their spikes had about two fewer kernels. Kernels of BW329 were 10 to 15% shorter and slightly wider and weighed 10% less, 52 vs 58 mg. The leaf blades of BW329 were slightly wider, and awns were slightly shorter. Grain yields of BW329 were about 15% lower than those of Bowman (2).
