In the present thesis,Zunyi population and Mouding population of Lilium sargenttiae Wilson was studied.The nested analysis of variance,based on the investigations of morphology and karyotype, was carried out.More than 20 morphological characters and karyotype were observed.The results are as follow: 1.Genetic variation exists in population extremely.About 21.16% variability is attributed to the differentiation among populations and the remaining 78.84% resided in this population.The variation of character generally comes from individuals.2.The karyotypical formulae of Zunyi population is 2?n=2?x=24=4?m(2?SAT)+4?st(4?SAT)+16?t,The karyotypical formulae of Mouding population is 2?n=24=4?m(4?SAT)+8?st(4?SAT)+12?t.The variation of chromosome generally comes from individuals,about 91.49%.Only 8.51% comes from the differentiation among populations.
