Abstract
The genetics of a virescent mutant was investigated in Bromus inermis Leyss. The trait was inherited as a single, tetrasomic recessive. Selfing the original mutant resulted in 4755 virescent:21 green seedlings when grown at 15 °C. From the data it was concluded that the mutant was homozygous for the virescent gene and that the occasional green, selfed seedlings probably arose by outcrossing.
