摘要
百合是著名的花卉，在国际切花生产中占有重要地位。切花百合又以花朵向上开放的钟形花为佳。文章利用东北产钟花组的毛百合（Ｌｉｌｉｕｍｄａｕｒｉｃｕｍ）和花色鲜红的细叶百合（Ｌ．ｐｕｍｉｌｕｍ）为亲本，进行百合种间杂交，试图培育出适合东北室外栽培的，且花形、花色优良的百合新品种。试验所得杂种种子在２０℃恒温箱内的培养皿中发芽率为５４％，成苗率为发芽种子的２７％。胚培养的杂种种子发芽率为７３．２％，明显高于培养皿条件下的发芽率。通过种子形态、幼苗分化及子叶、真叶特征比较，发现杂种的特征基本介于亲本之间。
Lily is famous for its important standing in international cutting flower production. In the cutting lily, the bell flowers which the bloom is upward are welcome. In order to cultivate new wilily variety which flower shape, colour are fine and adaptable for outdoor cultivation, we carried out the study of hybrid between species. Lilim dauricum of bell flower section which is native in Northeast of China and L.pumilum which flower is bright red were taken as parents. Experimental results showed that germination percentage of hybrid seed in 20℃ thermostat is 54%, and seedling rate takes up 27% of germination seeds. Germination rate of hybrid seeds by embryo cultivation is 73.2%, greatly higher than that of cultivating in culture utensils. By comparison of classification characteristies in seed shape, seedlig differentiation, cotyledon and leaf, It is concluded that characteristics of hybrid are situated between parents, and hybrid chromosome displays some parent's peculiar features.
