摘要:

马铃薯是全球最重要的非谷物类粮食作物。杂交马铃薯育种,即将马铃薯由四倍体无性繁殖作物改造成二倍体种子作物,已经成为马铃薯领域的研究热点。过去十多年来,以二倍体为主要研究对象的马铃薯基因组学快速发展,进一步促进了马铃薯育种技术的变革。本文系统梳理了马铃薯基因组学发展的历程,以及基因组学研究如何助力解决杂交马铃薯育种的两个难题——自交不亲和与自交衰退,并推动马铃薯基因组设计育种体系的构建,使马铃薯育种迈向4.0时代。

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.
