用染色体常规压片法对‘红霸天’百合（L ilium hybrids‘Hongbatian’）的根尖进行核型分析，并对其染色体制片技术适宜的取样时间进行了探讨。研究发现：‘红霸天’百合根尖取样时间以上午10∶00～10∶30为宜；染色体核型公式：2n＝36＝6m＋24st（4SAT）＋6t；最长与最短染色体的长度比值2.59，臂比值大于2∶1的染色体占全部染色体的比例为83.33％，平均臂比值为4.97；核型不对称系数为77.80％。

Using the root of Lilium hybrids ‘Hongbatian’ as materials ,this study aims to uncover the chromosome karyotype and discuss the appreciate sampling time in the chromosome preparation method of L .hybrids ‘Hongbatian’ . The results shows are as follows :The best sampling time of L . hybrids‘Hongbatian’ root is from 10∶00 to 10∶30 in the morning ;Karyotype formulae is 2n=36=6m + 24st (4SAT )+6t ;The ratio of the longest chromosome to the shortest one was 2.59 ;Approximately 83.33%arm ratio of chromosome was more than 2∶ 1 ,and the average ratio of arm was 4.97 ;The asymmetrical karyotype coefficient was 77.80% .
