A circular DNA is provided comprising endogenous DNA common to both genetically modified wheat and non-genetically modified wheat along with one or more pieces of DNA each having a sequence present specifically in a strain of genetically modified wheat. Also provided is a method for determining a mix rate of genetically modified wheat in a test sample.

Method for detecting and quantifying endogenous wheat DNA sequence

A method of testing the presence/absence of wheat in a food by performing PCR with the use of primers which have been designed on the basis of data obtained from a part of a gene of wheat. This method is highly useful in detecting a trace component contained in a food or identifying a harmful allergen of wheat.

Method of testing wheat

The invention provides a means for estimating the end use qualities of wheat flour that will be obtained in the future from the harvested wheat at an early stage before maturation of the wheat seeds. The invention relates to a method for estimating the end use qualities of a matured wheat seed, comprising measuring the expression level of at least 1 gene selected from genes, each of which is defined by any one of the nucleotide sequences of SEQ ID NOS: 1 to 121 in immature wheat.

Method for estimating end use qualities of wheat at growth stage

A method for detecting the presence/absence of a specific substance in foods by performing PCR using primers which are designed on the basis of data obtained from a part of a gene of the specific substance. This method is highly useful in detecting a trace component contained in a food or identifying a specific harmful allergen.
