A chemical hybridization agent having the formula
wherein X represents hydrogen or one to three groups, identical or different, selected from halogen, CF3, C1-C3 alkyl, C,-C3 alkoxy or C1-C4 alkanoyl, Y represents hydrogen or one to three halogens, Z represents OR (wherein R represents H, a metal or ammonium cation, a C1-C4 alkyl group, a C1-C4 alkenyl group or a C1-C4 alkynyl group) or NR1R2 in which R, and R2 are independently H, C1-C4 alkyl, C1-C4 alkenyl or C1-C4 alkynyl and agronomically acceptable salts thereof.
Method of sterilizing self-pollenizing plant, such as cereals, with said compounds and of producing hybrid seed of such plants.
