体细胞无性系变异与作物改良

近些年来，植物体细胞无性系变异研究进展较快，在多种作物中由体细胞胚胎发生获得再生的例子很多．这篇综述简要地回顾了主要农作物体细胞无性系变异与植物改良的研究工作．并记叙了２０年来所取得的重要进展．包括水稻、玉米、大豆、甘蔗等作物的无性系变异结果．为进一步开展体细胞无性系变异研究提供了线索．

SOMACOLNAL VARIATION AND IMPROVEMET OF PLANT (REVIEW)

There is a noticeable advance in plant somaclonal variation research in recent years.The successful rugeneration from embryogenesis has been obtained in many species. This review provides a briet history of the early work on ma jar crops somaclonal variation and improvemet. And docunts the advances made during the past 20 year which have made it possible to noticeable results from somaclonal variation. in eluding rice,maize. soybean,Sugarcane. Beside some physiological results inroleved in somadonal variation research.
