摘　　要：通过综述国内外杜鹃花自然杂交与远缘杂交的研究,归纳了前人在杜鹃花自然杂交以及远缘杂交取得的成果,杜鹃花自然杂交现象较为频繁,自然杂交后代的发现能大大缩短杜鹃花育种进程.远缘杂交主要存在花粉管生长异常、胚败育、杂交苗白化三个问题,通过一定技术手段可以解决.尽管杜鹃花远缘杂交整体成功率较低,亲本间可配性差异大,然而远缘杂交能够创造新种质、转移目标性状,同时有助于研究种间亲缘和进化关系.The results of domestic and international research about natural hybridization and distant hybridization of Rhododendron were summarized.The natural hybridization of Rhododendron was relatively frequent in the wild,and the process of Rhododendron breeding could be greatly shortened by this phenomenon.There existed three problems in distant hybridization primarily,such as abnormal growth of pollen tube,embryo abortion and albino hybridization,which could be solved by some technical means.Although the overall success rate of distant Rhododendron hybridization was relatively low,there was a great difference between different crosses.However,distant hybridization could create a new germplasm,transfer target traits,and meanwhile could help to study the relationship between species and phylogenetic relationships.
