“甘蔗复合群”能源植物遗传育种研究进展

“甘蔗复合群”是一类极具生物能源开发潜力的禾本科C4植物。近年来由于世界能源危机的影响和植物遗传育种研究的发展，国内外学者对“甘蔗复合群”植物资源评价和能源育种研究越来越重视。本文介绍了“甘蔗复合群”的基本概念、属种分类及核心类群等研究背景。同时以甘蔗属和芒属核心资源为例，从“甘蔗复合群”能源植物遗传育种的角度综述了国内外相关研究进展。旨在总结前人的理论研究成果和杂交育种实践经验，探讨相关类群在植物系统分类和种质资源利用中存在问题与对策，为我国“甘蔗复合群”能源植物的应用基础研究和产业化开发利用提出建议。

Progress on the Breeding of Energy Plants Comprisingthe “Saccharum Complex”

The “Saccharum complex” (Gramineae) is composed of C4 plants with high bioenergy potential. In recent years, because of the world energy crisis and developments in plant genetics and breeding, researchers at home and abroad have paid more attention to resource evaluation and bioenergy breeding of the “Saccharum complex”. This paper provides background to the taxonomy and key members of the “Saccharum complex” and reviews domestic and foreign progress on breeding the “Saccharum complex” using the core species, Saccharum and Miscanthus, as examples. The major purpose is to summarize previous research on breeding the “Saccharum complex”, and to highlight problems and solutions regarding phyletic classification and germplasm resource utilization of related taxa. Some suggestions are also given on future basic research and industrial exploitation.
