摘 要 ：通过对杜鹃花属十余年来所做的59对杂交组合的实验发现：（1）二倍体与二倍体的杜鹃花种间杂交亲和力强，座果率为37.5％～100％；（2）二倍体与多倍体的杜鹃花杂交无亲和力，座果率为0；（3）同亚属不同亚组之间二倍体种的杜鹃花杂交亲和力强；（4）不同亚属之间的杜鹃花种间杂交不育。

Abstract:Over the past ten years, 59 pair different combination of the genus Rhododendron were studied in Kunming Botanical Garden. The result shows that (1) diploid species x diploid species shows good affinity, the rate of fruit is 37.5%--100%, (2) it has not affinity if diploid species x polyploid species, (3) it shows good affinity if the parents from same subgenus and same group even the parents belong to different subsection, (4) they are markedly sterile if the parents belong to different subgenus.
