BGS 561, Erectoides-h, ert-h
Stock number: BGS 561
Locus name: Erectoides-h
Locus symbol: ert-h
Previous nomenclature and gene symbolization:
Erectoides-25 = ert-25 (3).
Inheritance:
Monofactorial recessive (3).
Located likely in chromosome 5HL (1); ert-h.25 is associated with a large number of donor parent SNP markers in 5H bins 11 to 14, markers 1_1090 to 2_0536 (positions 203.85 to 271.24 cM), of the Bowman backcross-derived line BW310 (1).

Description:
Plants are semidwarf (about 3/4 normal height), and spike density is increased only slightly (5). Plants of the Bowman backcross-derived line for ert-h.25, BW310, headed 5 to 7 days later than Bowman. The number of kernels per spike for BW310 increased by 3 to 5, but rachis internodes were slightly shorter, 3.9 vs. 4.4 mm. Grain yields for BW310 were up to 20% lower than the Bowman yields (2).
