摘　　要：巴西橡胶树早在20世纪70年代就已实现通过体细胞胚状体发生途径再生植株,但到目前为止,植株再生频率仍然较低,且只有少数无性系能够实现体外形态发生。橡胶树的离体培养难度大,是进行基因工程育种的主要障碍,本文对巴西橡胶树遗传转化技术研究进展进行综述,并讨论影响转化成败的关键因素与技术改进方向。The technique of somatic embryogenesis in Hevea brasiliensis was developed in 1970s. But only a few Hevea clones can now produce somatic embryogenesis through this technique, and the frequency of somatic plantlet regeneration in vitro is still low up to now. It is difficult to establish a high genetic transformation system for reconstructing the inheritance of Hevea at the molecular level. The general principles and possible problems in transformation are analyzed, and the progress and achievements in Hevea genetic transformation are reviewed.
