SOYBEAN ANTI-POD-SHATTERING MAJOR QTLqPD05, AND MAPPING METHOD AND APPLICATION THEREOF

摘要

The present invention provides a soybean anti-pod-shattering major QTLqPD05, and a mapping method and application thereof, and belongs to the field of QTL mapping. The soybean anti-pod-shattering major QTL is mapped on the chromosome 5 of soybean at a physical position between 40448596-40703417. For the method for mapping the soybean anti-pod-shattering major QTL, a SLAF marker is screened at the whole genome level of the soybean by utilizing a SLAF-seq sequencing technology, so as to explore the QTLs related to pod shattering from this population. By using a material of a RIL7 population which has pod-shattering soybean and anti-pod-shattering soybean as the parents, a high-density genetic linkage map covering the whole genome of soybean is constructed, and QTL mapping of the anti-pod-shattering trait is carried out on this population to obtain QTLs related to anti-pod-shattering. In addition to this, the construction of the high-density genetic linkage map and the identification of the novel QTLs related to anti-pod-shattering specific to this population provide a reference for efficient QTL mapping of soybean.
