Claim 0:
1. A method for identifying a sorghum herbicide-resistant plant, comprising:
a) providing a nucleic acid sample from a non-transgenic sorghum plant;
b) amplifying a region corresponding to the AHAS gene present in said nucleic acid sample from a sorghum plant;
c) identifying a herbicide-resistant sorghum plant based on the presence of one mutation in the amplified nucleic acid sample, where said mutation confers resistance to herbicides from the imidazolinone group, wherein said one mutation comprises an Ala93Thr substitution in an encoded polypeptide, wherein said polypeptide has acetohydroxyacid synthase activity, and wherein the nucleic acid sample comprises SEQ ID No. 1; and
d) applying one or more imidazolinone herbicides to the identified herbicide-resistant sorghum plant, wherein the sorghum plant has increased resistance to one or more imidazolinone herbicides as compared to wild-type sorghum plants.
