[The allozyme analysis of the genetic differentiation in self-inbred early generations of Lilium formolongi Hort].

The genetic diversity and differentiation of Lilium formolongi Hort. lines in self-inbred early generations were studied by allozyme electrophoresis. The results showed that mean allele number/locus, percentage of polymorphic loci, average observed heterozygosity and average expected heterozygosity were decreased with the increment of self-inbred generations. The purified loci, purified speed, fixed alleles and increment of genetic differentiation were different among lines because of selection and self-inbred. The mean genetic distances among F4 lines were larger than that of F3 lines, serving as another evidence to prove the differentiation among lines.
