摘要:
优异种质资源的开发利用是作物育种取得突破的关键。甘蔗(Saccharum spp.)是世界主要糖料作物,但长期以来遗传改良进展缓慢,制约了甘蔗品种选育取得进一步的突破。甘蔗野生种割手密(Saccharum spontaneum L.)是甘蔗属中利用最成功的野生种,如何进一步开发利用其育种潜力无疑是破解这一现状的积极选择。本文简要概述了割手密在遗传多样性及创新利用方式等方面的研究现状,重点分析了割手密创新利用中存在的不足,并探讨了进一步开发利用割手密育种潜力的新思路。

Abstract:
The significant advance on crop breeding largely relies on exploration and utilization of excellent germplasm resources. Sugarcane (Saccharum spp.) is the major sugar crop in the world, but for a long time limited progress in sugarcane breeding has been made. Saccharum Spontaneum L. is a wild species in Saccharum L, and this species as the most successful example has been used in sugarcane breeding. Optimal use of this wild species Saccharum Spontaneum L. in sugarcane breeding is of interest to overcome this limitation. In this review, we summarized the progress on the genetic diversity analysis and innovative utilization of Saccharum Spontaneum L, analyzed the limitations restricting its innovative utilization, and ultimately raised prospective for future innovation and utilization in sugarcane breeding.
Key words:  Sugarcane germplasm resources  Innovative utilization  Saccharum spontaneum L.  Genetic improvement
