摘　　要：主要李生产国通过有性杂交育种已经成功地选育出一批具有早中晚熟,丰产,果肉硬,中大果型,抗寒和耐低温的中国李(Prunus salicina)优良品种。欧洲李(P.domestica)的品种选育倍受欧美一些国家的重视,先后选育出果皮蓝、紫、黄、红色,含糖量高,抗寒,自花结实和极丰产的品种。除中国李与中国李和欧洲李与欧洲李的种内杂交外,中国李、樱桃李、杏李、比西砂樱李、美洲李、狭叶李、果酱李、雁李和加拿大李之间已经杂交成功,并获得杂种单株。已经从樱桃李、中国李、杏李和比西樱李与杏和梅杂交后代中选育出一些较好的种间杂交栽培品种。还介绍了国内外目前新品种的育种目标。The progress of plum breeding in the world and the promising new varieties bred by the different countries are introduced in this article.The plum industry in different countries is also mentioned. At present the leading plum grown species are Chinese plum (Prunus salisina Lindl.) and European plum (Prunus domestica L.). Many countries have bred a series of plum new varieties,including early,mid and late seasons,which generally are good cropping, resistant to coldness, and have large fruit size with good eating quality. Some of the new European plum varieties have high sugar content with blue .purple, yellow or red skin color, not only suitable to be used for fresh consumption but also for processing.Besides the interspecific crossing used for breeding new variety between Chinese plum and European plum varieties, the interspcific crosses between the other species are also conducted and some distinguished new varieties have been received.
