The invention relates to a high-oleic acid peanut mutant gene AhFAD2B-814 and application thereof and belongs to the field of plant molecular breeding. A nucleotide sequence of the mutant gene AhFAD2B-814 is shown as SEQ ID NO.: 1 and consists of 1140 bases. The high-oleic acid peanut mutant gene AhFAD2B-814 and the application thereof provided by the invention have the benefits that a mutant nucleotide sequence of a peanut high-oleic acid mutant oleic acid dehydrogenase gene can be introduced into other peanut varieties or strains with common oleic acid contents by applying conventional breeding methods such as hybridization, backcrossing and the like, the oleic acid content of a target variety or strain introduced with the mutant nucleotide sequence of the gene AhFAD2B-814 is improved, the genetic diversity of a high-oleic acid peanut variety (strain) is significantly increased, and the genetic basis of a high-oleic acid peanut is widened; during high-oleic acid peanut breeding, by selecting a peanut materi
