Abstract: The application discloses non-naturally occurring barley plants with increased resistance to herbicides, particularly imidazolinone herbicides. Also disclosed are the barley seeds per se, an isolated nucleic acid incorporating the nucleic acid sequence conferring imidazolinone resistance, a method of inhibiting weed growth in the vicinity of a barley plant, an a method of growing a barley crop. Seeds have been deposited at NCIMB.

Abstract: The application discloses non-naturally occurring barley plants with increased resistance to herbicides, particularly imidazolinone herbicides. The imidazolinone resistance is conferred by mutant acetohydroxy acid synthase (AHAS), more particularly by AHAS with a SER653 mutation. Also disclosed are the barley seeds per se, an isolated nucleic acid incorporating the nucleic acid sequence conferring imidazolinone resistance, a method of inhibiting weed growth in the vicinity of a barley plant, an a method of growing a barley crop. Seeds have been deposited at NCIMB.
