摘要
中国是世界上薯类生产大国,马铃薯、甘薯和木薯等在农业产业发展中发挥着重要作用。薯类主粮化已成为保障我国粮食安全的新措施,但其基础研究相对于"大作物"如水稻、玉米等还存在较大距离。开展三大薯类(木薯、甘薯和马铃薯)种质创新和新品种培育对推动薯类产业化意义重大,其中分子育种是其遗传改良的生长点和动力。从深化利用种质资源和基于基因组信息的基因挖掘,以及薯类共性和个性生物学问题的联合攻关等重要方面进行综述,阐明了薯类研究现状和趋势,旨为促进薯类分子育种技术的提升提供参考。
China is the world’s biggest producer of root and tuber crops. Potato, sweet potato and cassava play important roles in promoting agriculture industrialization and food security, but their basic research, as compared to‘major crops’such as rice and maize, is much retarded due to difficulty in molecular study and breeding. Therefore, germplasm enhancement and new cultivar breeding are essential to promote utilization of root and tuber crops, in which molecular breeding is the trends and driving force. This review aims at briefly highlighting the advances of research on root and tuber crops in China through deepening their germplasm exploration and functional genomics as well as the joint efforts towards the common and special scientific questions they faced, which provides the reference for improved breeding technology in these crops.
