摘要:

作为人口和农业大国,我国政府历来重视农业问题和粮食安全。基于人口众多、耕地资源有限的国情限制,我国把依靠科技发展提升单产水平作为保证我国粮食安全的主要手段。在国家的积极布局和大力支持下,近年来我国在作物育种理论和技术上不断突破和创新。作物重要农艺性状的解析和具有育种价值的等位基因利用、基因编辑技术的创新和应用、基因组育种和从头驯化策略以及转基因大豆和玉米产业化试点等为我国作物新种质的创制提供了新思路和新策略。梳理和回顾了我国在此领域取得的一些具有代表性的成果,并对发展前景进行了总结和展望。

Abstract:

As a country with a large population and agriculture, our government has always attached great importance to agricultural issues and food security. Based on the national conditions of large population and limited arable land resources, China tolces relying on scientific and technological development to improve the yield level as the main means to ensure the food security. With the active deployment and strong support on agricultural development, China has made continuous breakthroughs and innovations in crop breeding theory and technology in recent years. The genetic dissection of important agronomic traits of crops, the utilization of gene alleles with high breeding value, the innovation and application of gene editing technology, genomic breeding and de novo domestication strategies, industrialization pilot of transgenic soybean and maize provide new ideas and strategies for the creation of new crop germplasm in China. This paper sorted out and reviewed some representative achievements made by China in this field, and briefly summarized and looked forward to the development prospects.

Key words: biological breeding, gene editing, de novo domestication, transgenics, germplasm enhancement
