Abstract

The present invention relates to the use of the ALS inhibitor herbicides for controlling unwanted vegetation in ALS inhibitor herbicide tolerant Brassica plants, more especially, the present invention relates to the use of ALS inhibitor herbicides for control of unwanted vegetation in Brassica growing areas which Brassica plants comprise non-transgenic mutations of their endogenous acetolactate synthase (ALS) genes I and III.

First claim

The invention claimed is:

1. An ALS inhibitor herbicide applied to Brassica growing area, comprising a Brassica plant comprising an altered ALS I Brassica polypeptide comprising an amino acid different from an amino acid corresponding to position alanine205 (A205) of SEQ ID NO: 10, wherein said amino acid different from alanine is valine; and an altered ALS III Brassica polypeptide comprising an amino acid different from an amino acid corresponding to position tryptophan574 (W574) of SEQ ID NO: 10, wherein said amino acid different from tryptophan is leucine, wherein said ALS inhibitor herbicide is effective in controlling unwanted vegetation in said Brassica growing area.
