Abstract

Abstract:

Potatoes are the most important non-grain food crop in the world. Hybrid potato breeding, that is, transforming potato from tetraploid asexual crop to diploid seed crop, has become a research hotspot in potato field. In the past decade, the rapid development of potato genomics with diploid as the main research object has further promoted the change of potato breeding technology. This paper systematically reviews the development process of potato genomics, and how genomics research can help solve the two difficult issues of hybrid potato breeding, self-incompatibility and inbreeding depression, and promote the construction of potato genome design breeding system, so that potato breeding will move towards the 4.0 era.

Key words: potato, genome, self-incompatibility, deleterious mutation, hybrid breeding
