Patent ID: 7977087

Claim:
A gene detection instrument for detecting expression or polymorphism of genes existing in a genome of Triticeae species, said gene detection instrument comprising a support on which are immobilized at least 50 polynucleotides selected from the group consisting of: (a) polynucleotides with partial base sequences of chromosomal DNA of barley and (b) polynucleotides in which a base sequence constituting part of entire base sequences of chromosomal DNA of barley is joined to non-continuous base sequences constituting other parts of the entire base sequences of chromosomal DNA of barley wherein the polynucleotide immobilized on the support comprises; at least one kind of polynucleotide is selected from the group consisting of: (1) polynucleotides with the base sequences of SEQ ID NO: 1 through 5780; (2) a polynucleotide whose partial sequence comprises all of any one of the polynucleotides set forth in (1); and (3) a polynucleotide whose partial sequence comprises: all of a base sequence of SEQ ID NO: n (where n is an odd number), or in the polynucleotides set forth in (1), and all of a base sequence of SEQ ID NO: n+1, or in the polynucleotides set forth in (1); the polynucleotides being mapped on barley chromosomes for an entire genome of barley, and the polynucleotides being mapped on the support at an average density of no greater than 30 cM; regions on the support in which said at least 50 polynucleotides are respectively immobilized being arranged in the same order as a chromosomal order of said at least 50 polynucleotides immobilized on the support, or information indicative of a chromosomal order of said at least 50 polynucleotides immobilized on the support being appended to regions on the support in which said at least 50 polynucleotides are respectively immobilized.
