Class Level 1 Glume Colour and Awn Colour
Level 2 Red (brown/bronze/black) glumes
Level 3
Level 4
Symbol Wild Type Rg-A1
Allele Rg-A1aRg-A1bRg-A1c Rg-A1d
Synonyms Bg(b)
Germplasms dv:G3116{282}
Comment At the diploid level Rg-A1c (Bga) and Rg-A1d (Bgb) were determinant and caused a solid black glume and a black line at the margins of the glume, respectively {282}.
A single factor for black glumes was reported in diploid, tetraploid and hexaploid wheats {1347}. Linkage with Hg was demonstrated at all levels of ploidy, indicating a common gene on chromosome 1A; Bg is epistatic to Rg.
