Abstract:

Potato is one of the main food crops in China, and research on potato molecular breeding research is of great significance. In the diploid potato, QTL mapping and cloning of important genes has been reported extensively; The development of tetraploid linked analysis software, genetic map construction in tetraploid potato and QTL mapping have also made breakthrough progress in recent years. Meanwhile, molecular markers are an important supplement method for potato breeding and it can quickly and accurately screen out multiple good traits. In this paper, the progress of the QTL mapping, cloning of important agronomic traits in potato and 3 resistance traits linkage markers breeding were summarized, to provid a reference and practical basis for accelerating potato molecular breeding.

Key words: Potato, QTL, Molecular marker, Breeding
