Abstract

Abstract: The genetic structure of seven Ambrosia trifida population from northeast China were investigated using horizontal starch gel electrophoresis ten putative loci from ten enzyme systems were statistics analysis. The result showed very high genetic variability in population of A. trifida, with a percentage of polymorphic loci of 80.00%, an average number of alleles per locus of 1.80. The expected heterozygote was 0.375, the means of genetic identity and genetic distance were 0.959 and 0.042.

Key words: Ambrosia trifida, Allezyme, Genetic variability, Genetic structure
