This paper described methods analysing variation in neutral molecular and fitnese-related quantita-tive traits.In the first part of paper we distinguished between genotypic and genetic variation,and discussed the problems of inferring allele frequencies from samples of ramet that may or may not belong to different genets.In addition,in the second part of paper,we reviewed spatial and temporal variability in genotypic variation in clonal population of Leymus chinensis and others as inferred from direct observation of individual genets in the field or form indircct determinations of multilocus genotypes using molecular techniques.We also discussed how seeding recruitment,environmental disturbancc,or the growth from of genets may influence genet population dynanics.We dealt with clonal population structure,population sulxilivision,and gene folw all of which can be estimated from the pattern of genetic variation at presumably neutral loci.$$$$
