分子标记技术在大麻育种中的发展和应用是最近的，仅可追溯到20世纪90年代中期。综述了该领域的主要研究成果。讨论了利用RAPD、AFLP和微卫星技术对大麻种质资源的分析，以及其对大麻物种概念仍有争议的影响。基于DNA的标记也被应用于法医学领域，试图区分合法作物和非法作物。然而，分子标记在育种中的主要应用是随着与雄性和一些最相关的化学型密切相关的标记的发展而实现的。几个研究小组在鉴定和表征与纤维质量和数量有关的基因以及确定大麻育种的另一个非常重要的目标--单纤维素方面进行了积极的研究。此外，正在开发与新的、潜在有用的化学型相关的标记，用于药用大麻的标记辅助育种。
The development and applications of molecular markers to hemp breeding are recent, dating back only to the mid-1990s. The main achievements in this field are reviewed. The analysis of Cannabis germplasm by RAPD, AFLP and microsatellites is discussed, with its consequence for the still debated species concept in Cannabis. DNA-based markers have also been exploited in the field of forensic science, in an attempt to discriminate licit from illicit crop. The main applications of the molecular markers to the breeding, however, have been achieved with the development of markers closely linked to the male sex and to some of the most relevant chemotypes. Active research is carried out by several groups in the field of identification and characterization of the genes involved in fiber quality and quantity, and in the determination of monoecy, another very important target of hemp breeding. Besides, markers associated to new, potentially useful chemotypes are being developed, for the marker-assisted breeding of pharmaceutical Cannabis.
