BGS 564, Erectoides-p, ert-p
Stock number: BGS 564
Locus name: Erectoides-p
Locus symbol: ert-p
Previous nomenclature and gene symbolization:
Erectoides-44 = ert-44 (3).
Inheritance:
Monofactorial recessive (3).
Located likely in chromosome 5HL (1); ert-p.44 is associated with SNP markers from 2_1480 to 2_1390 (positions 137.96 to ≈173.0 cM) in 5H bins 08 to 10 and with SNP markers in small regions from 2_1370 to 1_1486 (positions 199.54 to 202.70 cM) in 2H bin 13 and from 2_0607 to 1_0863 (positions 52.41 to 64.85 cM) in 3H bins 04 to 05 of the Bowman backcross-derived line BW320 (1).

Description:
Spikes are semicompact with an estimated rachis internode length of 2.7 mm, and the culm length is 5/6 of normal (5). Plants of the Bowman backcross-derived line for ert-p.44 (BW320) had shorter rachis internodes, 3.8 vs 4.6 mm, and were 10% shorter. Kernels of BW320 were slightly shorter and wider, however grain yields did not differ from those of Bowman (2).
