摘要
将二倍体黄花菜诱变成同源四倍体黄花菜，一般表现花蕾增大、增重，品质提高．本试验用秋水仙碱处理黄花菜“长嘴子花”组培中所形成的球状体，诱导成变异试管苗．经鉴定和选育，首次获得食用黄花菜同源四倍体新品系．该四倍体与二倍体在外部形态、产量性状、品质特性、细胞学及细胞遗传学特征上明显不同．
The autotetraploid daylily modificated from diploid showed larger and weighter flower bud than the diploid,and better quality.In our study,the variant plantletes were ob-tained from the globulas treated with colchicine,these globulas were induced from callus of daylily in vitro.The new strain,autotetraploid daylily,was obtained for the first time by iden-tifying and breeding these variant plantletes.The autotetraploids were obviously different from the diploid in morphology,yield quality,cytology and cell genetics.
