摘　　要：对百合属（Ｌｉｌｉｕｍ）１０种植物的自花传粉和种间传粉进行了初步观察分析，结果为：轮叶百合、有斑渥丹、王百合及毛百合自花不孕。川百合和条叶百合同株异花授粉的亲和性好于同花授粉的亲和性。在常规授粉条件下，种间授粉亲和性与形态学亲缘关系不完全一致。在１３组杂交组合中，同是卷瓣组的细叶百合和垂花百合，正反交分别得到１６％和２５％的有胚种子；同为钟花组的毛百合和有斑渥丹，正反交均不座果；卷瓣组的条叶百合×百合组的王百合得到１２％的有胚种子，种子发芽率６４％；轮叶百合（轮叶组）×王百合得到８２％的有胚种子，种子发芽率８５％。Self-pollination and interspecific-pollination were studied in 10 species of Lilium.The result shows that in L.d istichum,L.concolor var.pulchellum,L.dauricum and L.regale self-pollination is sterility.Affinity of cross-pollination in one plant is better than self-pollination in L.davidii and L.callosum.Affinity in interspecific-pollination is different sith norphology with convention.Thirteen crossing groups were researched.In same group,after reciprocal crosses of L.pumilum and L.cernum,we can get 16% and 25% albuminous seed,L.callosum ×L.regale,we can get 12% albuminous seed,that it germination rate is 64%.In another group,reciprocal crosses of L.dauricum and L.concolor var.pulchellum,had not seed.In L.distichum ×L.regale,we can get 82% albuminous seed,that it germination rate is 85%.
