BGS 185, Brachytic 5, brh5
Stock number: BGS 185
Locus name: Brachytic 5
Locus symbol: brh5
Previous nomenclature and gene symbolization:
Brachytic-m = brh.m (4).
Inheritance:
Monofactorial recessive (4, 6).
Located in chromosome 4HS (5); brh5.m is near the int-c (intermedium spike-c) locus (5); brh5.m is about 13.0 cM proximal from SSR marker Bmac0310 near the boundary between 4H bins 06 and 07 (1); brh5.m is associated with SNP markers 2_0145 to 1_1500 (positions 2.58 to 115.9 cM) in 4H bins 01 to 08 of the Bowman backcross-derived line BW096 (2), likely in 4H bin 06.

Description:
Plants of the Bowman backcross-derived line for brh5.m, BW096, were about 3/4 normal height and their awns were about 3/4 of normal length. Peduncles were less than 2/3 normal length. Seedling leaves of brh5 plants were relatively short. The kernels of brh5 plants were shorter than those of Bowman and weighed about 30% less. BW096 plants lodged easily and the grain yields were about 1/2 those of Bowman (1, 3).
