鳞茎草花中最为著名的要数百合科郁金香属。它的栽培历史悠久,品种群的杂合性很大,自然突变也时有发生。荷兰De Mol等首先进行了郁金香辐射育种研究,这方面的工作做得最多。此外瑞典Carlsson、波兰Grabowska等、日本Matsubara、Matsuda、Myodo、Nezu等都报道了这一工作。供试品种的选择是一件不容易的事。据报道,似乎选用粉红色花的品种作试材可获得较理想的花色突变。其他花色也可产生突变,但黄花的突变极少。宜选用健壮而优质的新品种作为照射材料,老品种的诱变效果较差。如果想知道可否产生花色突变,最好在鳞茎收获后立即进行照射,第二年观察生长点是否产 Bulbous flowers in the most famous to hundreds of families Tulipa. It has a long history of cultivation, the heterozygosity of breeds is very large, and natural mutations occur from time to time. Netherlands De Mol first carried out a study of tulip radiation breeding, the most done in this area. In addition, Carlsson in Sweden, Grabowska in Poland, Matsubara in Japan, Matsuda, Myodo and Nezu all reported this work. The choice of test varieties is not easy. It is reported that it seems that the selection of varieties of pink flowers as the test material can be more desirable color mutations. Other colors can also produce mutations, but very few mutations in yellow flowers. Should choose robust and high quality new varieties as irradiation materials, the old varieties of mutagenic effect is poor. If you want to know whether color mutations can be made, it is best to shoot the bulbs immediately after irradiation, the second year to observe whether the growth point of production
