| 摘 要： | 以马铃薯根尖为材料，用对二氯苯饱和溶液、1％秋水仙碱以及冰水混合物进行顸处理，醋酸洋红和卡宝品红染色，比较不同预处理方法和染色液对制片效果的影响，结果表明，预处理采用1％秋水仙碱中期分裂相多，染色体分散，而染色液采用卡宝品红着色效果好；鉴定了从CIP引进的马铃薯材料60份，其中二倍体材料10份，三倍体材料7份，四倍体材料43份。

| Abstract: | To compare the infltmce of different pretreatment and coloration, the root tips of potato were pretreated with saturated paracide, 1% colchicines and glaciofluvial mixtute colouted with carbolic acid rubin and acetate rubin. The results showed that chromosome scattered relatively with 1% colchicines , coloration was distinct with carbolic acid rubin; 60 potato materials introduced from CIP was identified, which include 10 dipliod, 7 triploid and 43 tetralont. |
