摘要: 由于复杂的遗传背景、较低的可育性和缺乏优异种质资源等因素给甘蔗品种改良带来了很大的困难,而通过转基因技术为甘蔗品种改良提供了有效的途径。甘蔗通过转基因,不仅在其抗虫性(螟虫和蚜虫)、抗病性(白条病、花叶病和黑穗病)、 蔗糖改良(蔗糖产量、蔗糖纯度和色泽)、抗除草剂、抗旱性等方面已经取得了很大的进展,而且转基因甘蔗作为生物反应器生产重组蛋白(GM-CSF 等)和生物塑料聚羟基丁酸酯(PHB)也取得了很好的成果。综述甘蔗主要性状遗传改良研究进展、转基因存 在的问题以及转基因安全性研究状况,并对今后的甘蔗转基因育种前景和研究方向进行分析。

Abstract: The genetic complexity of sugarcane coupled with the nonavailability of fertility and excellent resource in the germplasm bring has made conventional breeding in sugarcane difficult. Alternatively, transgenic technology has become a handy tool for imparting objective traits to an elite variety which is otherwise superior for most other agronomic traits. A number of transgenic sugarcane lines have been developed with genes expressing insect resistance, disease resistance, sugar improvement, herbicide resistance, recombination protein. In this review, genetic improvement for important agronomic traits, transgenic problem and biosafety were highlighted. Also, perspectives were discussed to analyze the research direction of transgenic breeding in sugarcane.
