摘要： 以60Co-γ射线辐照处理切花百合‘科瓦拉’、‘不同凡响’、‘双重惊喜’鳞茎，开展辐射诱变育种试验。经0、3、6、9 Gy60Co-γ处理的成苗（株）率‘科瓦拉’分别为100%、37.5%、0和0；‘不同凡响’的成苗（株）率分别为100%、35%、7.5%、2.5%；‘双重惊喜’的成苗（株）率分别为100%、100%、66.7%、0。结果表明，各处理对百合植株的生长和发育出现较明显的辐射损伤，主要表现在植株变矮，单株叶片数减少，花蕾数减少，开花延迟。用60Co-γ射线辐射诱变切花百合有明显效果，适宜诱变剂量因品种不同而变化。

Abstract: 60Co-γ ray irradiation Lilium‘Corvara’,‘Extraordinary’,‘Double Surprise Bulbs’, to carried out radiation mutation breeding experiment. The 0, 3, 6, 9 Gy 60Co-γ treated seedling (strain) rate‘Corvara’were 100%, 37.5%, 0 and 0;‘Extraordinary’seedling (strains) were 100%, 35%, 7.5%, 2.5%;‘Double Surprise Bulbs’seedling (strains) were 100%, 100%, 66.7%, 0. The results showed that the treatment on the Lilium plant growth and development had obvious radiation damaged, mainly in the plants grew shorter, reduced the number of leaves per plant, bud reduced the number of delayed flowering. With 60Co-γ ray radiation mutagenesis Lilium had a demonstrable effect, suitable for mutagenesis dose due to different varieties have changed.
