Abstract: Genetic variation of 23 varieties of foxtail millet collected from spring millet region and summer millet regions was studied. The results showed that 23 varieties had certain degree of genetic variation in molecular level, but the degree of variation was not significant. 13 primers yielded 56 polymorphic bands from 23 varieties and the average of polymorphic bands was 4.31 yielded by each primer. The primers S30 and S45 yielded 7 polymorphic bands, respectively, and which could be used to distinguish 13 varieties. The cluster analysis of RAPD makers indicated that the cluster type of genetic variation of varieties was not consistent with ecological type. Varieties from different regions could be clustered in the same type, and varieties from same regions might be clustered in different types.

Key words: Foxtail millet (Setaria italica Beauv.), Genetic variation, RAPD marker
