  • Patent number: 6207367
    Abstract: The invention is in a process of genetic mapping for plant identification and breeding purposes. The process utilitzes restriction fragment technology and detection of polymorphisms to build up a genomic “fingerprint” for a variety or isolate. The “fingerprint” is then compared to “fingerprints” of other varieties or isolates to determine both the degree of relatedness and homozygosity for identification and breeding purposes.
