Abstract
Polymorphic corn DNA loci useful for genotyping between at least two varieties of corn. Sequences of the loci are useful for designing primers and probe oligonucleotides for detecting polymorphisms in corn DNA. Polymorphisms are useful for genotyping applications in corn. The polymorphic markers are useful to establish marker/trait associations, e.g. in linkage disequilibrium mapping and association studies, positional cloning and transgenic applications, marker-aided breeding and marker-assisted selection, and identity by descent studies. The polymorphic markers are also useful in mapping libraries of DNA clones, e.g. for corn QTLs and genes linked to polymorphisms.
Claims2
1-18. (canceled)
A set of four oligonucleotides useful for identifying a polymorphism in corn DNA identified in Table 1 comprising
- (a) a pair of isolated nucleic acid molecules according to claim 16 which can hybridize to DNA which flanks a polymorphism identified in Table 1;
- (b) a pair of detector nucleic acid molecules which are useful for detecting each nucleotide in a single nucleotide polymorphism in a segment of DNA amplified by said pair of nucleic acid molecule primers of (a), wherein said detector nucleic acid molecules comprise
- (1) at least 12 nucleotide bases and a detectable label, or
- (2) at least 15 nucleotide bases, and wherein the sequence of said detector nucleic acid molecules is identical except for said nucleotide polymorphism and is at least 95 percent identical to a sequence of the same number of consecutive nucleotides in either strand of said segment of polymorphic corn DNA locus said polymorphism.
