In order to reveal the cytogenetic diversity of Lilium L. on chromosome, thestudy on chromosome number and karymorphology of 8 species and 2 variaties inNortheast China were carried out. It was found that the chromosome numberhad aneuploidal variation in both intraspecific and interspecific taxa. Frequencyand number of B-chromosomes could be related to the mode and ability ofasexual reprodution. Karyotypes of L. megalantum, L. amabile and L. cernum arereported for the first time. Tle seed set of triploid L....
