AB  - In this study, 49 samples of 43 <I>Rhododendron</I> sp. were studied by using RAPD to analyze their genetic diversity, relative ship and phylogeny. Four hundred and seven DNA fragments were amplified by 24 primers, the polymorphic rate was up to 98.03%. Their coefficient of Genetic Similarity (GS) was ranging from 0.2623~0.9059, which indicated rich genetic diversity in <I>Rhododendron</I>. The results showed that: 43 <I>Rhododendron</I> sp. were divided into 3 groups by RAPD, which was consistent with the division based on morphological characters, subgenus<I> Hymenanthes</I> had a closer relationship with subgenus <I>Rhododendron</I> than subgenus <I>Pseudorhodorastrum</I> and subgenus<I> Hymenanthes</I> was more primitive in phylogeny, subgenus<I> Pseudorhodorastrum</I> was the evolutive group in morphological characters, while subgenus<I> Rhododendron</I> was the transition one.
