Development of InDel Markers for Brassica rapa Based on a High-resolution Melting Curve

Brassica rapa is one of the most important leafy vegetable crops with large cultivated area in China. To increase the availability of DNA markers in B. rapa, we developed insertion-deletion (InDel) markers utilizing high-resolution melting (HRM) curve analysis. We designed primers for 252 InDels (≥ 3 bp) evenly distributed in the genome and tested gene polymorphisms with eight accessions. In total, 208 markers were specifically amplified, and...
