摘要:
The ideal marker system for tetraploid potato would be dosage-sensitive and have the ability to distinguish heterozygous genotypes with multiple haplotypes within the genomic region targeted by the marker. The objective of this study was to evaluate the utility of high-resolution DNA melting (HRM) for genotyping and polymorphism detection in diploid and tetraploid potato. Amplicon scanning, unlabelled probe, and short amplicon assays were developed for four candidate genes affecting tuber skin and flesh colour, and starch, and a marker linked to nematode resistance. Genotyping a set of 95 pota...
