中文摘要：

介绍了内部简单重复序列多态性（Inter-simplesequencerepeat，ISSR）分子标记技术的原理及特点，综述了ISSR技术在研究遗传多样性、亲缘关系及系谱分析、鉴定优良种质资源及构建遗传连锁图谱等应用进展，指出了目前ISSR分子标记在蓖麻种质改良和辅助育种等应用研究领域存在的问题，并提出今后的研究趋向。

英文摘要：

The principle and characteristics of the molecular marker techniques of inter-simple sequence repeat （ISSR）were described. The research of the ISSR molecule markers in the fields such as the research on genetic polymorphism,the analysis of genetic relationships and pedigrees, the identification of excellent germ plasms, the construction of genetic chain spectrums of a graph were summarized and the problems of the ISSR molecule markers that lied in the improvement of castor genes and auxiliary breeding at present were pointed out and the trend of future research was put forward.
