BGS 90, Erectoides-j, ert-j
Stock number: BGS 90
Locus name: Erectoides-j
Locus symbol: ert-j
Previous nomenclature and gene symbolization:
Erectoides-31 = ert-31 (4).
Inheritance:
Monofactorial recessive (4).
Located in chromosome 2H (3); ert-j.31 is based on linkage drag with the Gth1 (Toothed lemma 1) locus (3); ert-j.31 is associated with SNP markers 3_1205 to 1_1533 (positions 139.43 to 141.56 cM) in 2H bin 09 of the Bowman backcross-derived line BW313 (1), in 2H bin 09.

Description:
Spikes are semicompact with rachis internode length estimates of 2.4 and 2.6 mm, and culms are about 3/4 normal length (7). Compared to Bowman plants, the plants of the Bowman backcross-derived line for ert-j.31, BW313, were 10 to 20% shorter, peduncles were 20 to 25% shorter, the average rachis internode length was 3.4 vs. 4.6 mm, and kernels were 10% shorter. Spikes had 1 to 3 fewer kernels, kernels were 10 to 20% lighter, and grain yields were 10 to 20% lower than those of Bowman (2).
