用电子束辐射对菊花组培苗、唐菖蒲及百合种球进行诱变育种研究 ,旨在探索新的高效诱变育种途径。

STUDIES ON IRRADIATION BREEDING BY ELECTRON BEAM IN FLOWERS AND PLANTS

Electron beam was used to irradiate different flowers and plants.The results showed that the suitable doses were 30～50Gy for the young plant from cultured tissue of chrysanthemum,60～80Gy for gladiolus and 15～60Gy for lily.In these dose range,the posterity had higher variation and wider mutation range,and mutation characters were stable.The mutation rates were 18^2%～30^8% for chrysanthemum,8^7%～30^8% for gladiolus and more than 35% for lily.The blossom were 60,21,10 days earlier than the check for chrysanthemum,gladiolus and lily respectively.But the mutation rate of color varied greatly with different varieties.
